I replied to this your claim and I have noticed that my response has been taken down from the thread. It's fine. I guess Nigerians knows better anyways.

Many of our people will make you believe anything but the truth remains that SMS IS NOT A DEYE DISTRIBUTOR, THEY SIMPLY RESELL.

I posted the proof here and you guys took it down, I pity those who will get caught up i warranty issues.

GloryJoyeux:


You are wrong and I really don’t like to argue. They are authorised/official DEYE distributors.

Am looking at those battery cables, they don't seem to be above 16mm? I will suggest you do 35mm or at least 25mm considering the load as I assume you will be doing up 10kw average? I can even see from the image that you are already discharging at above 11kw

They are actually 35mm x 2 on each pole. I used single 35mm initially but they were heating up while charging at 240A.
So instead of linking the 2 batteries, I let each battery travel to the inverter on its own. Now the heating is gone.

I have the breakers to worry about now. It's rated 125A and I'm pumping 240A through it. Instead of it to trip, it's just there heating up.

Juror:

How is it able to read individual batteries? did you use a switch?

Batteries are connected in Parallel, RS485 Cable between Batteries (Using DIP switch for Battery 1: 10000 and Battery 2: 01001, and I made a special cable to link the Inverter and the Batteries.

Deye Inverters doesn't read Felicity Batteries out of box you will have to crimp a cable for CAN communication.

This image you posted - I am struggling to see the relevance to PV protective earthing.

As for the NEC expose on youtube, I am fairly sure responses to youtube comments as the authority for best practice will be dimly regarded by home insurance and the code compliance inspector. If you could reference the actual NEC codes you are referring to as for your position that would be nice - the ones you have paraphrased here are almost exactly the best practice I have been preaching.

The codes are not nice to haves but actually mandatory compliance requirements for a facility to inspection and qualify for insurance - try claiming insurance when lightning has damaged your property and you are unable to demonstrate code compliance and watch the claim thrown out. Here in Nigeria we do whatever we like, get lucky because we did not suffer an actual hit and call ourselves experts on doing it right.

Please read the things I said and see if you have issue with any particular one then we can discuss that very one in detail - to my mind it appears there is some conflation between connecting the designated earth point and chassis of equipment and frames of exposed outdoor objects to protective earth (Earthing) vs connecting the AC neutrals and DC negatives together or to thesame earth point (Grounding) and sadly these are also used loosely and interchangeably.

There is a limited number of cases where one may setup his PV protective earth and keep it isolated from the main facility earth and the codes cover these as well - these are more exceptions than the norm.

Again, let us leave quoting arcane references to code and pick one actual scenario or problem and we can work out the merits of various approaches strictly based on the risk vs protection trade offs the alternative approaches offer.

I think enough is been said on this topic already let's drop it.
At least people have gotten the message in relation to many different scenarios and they can decide exactly what to follow.

Electrical Codes are there in the open. People should go scroll through most of them that have covered Earthing or Grounding and deduct their methods accordingly.

For me whenever I acquire any electrical gadget I always look at the conformities first before installing them and if there are modifications I need to make to my existing installations, I make them. And then I will compare what changed from the prior conformities.
Some people might be stuck in the past with a certain information on their minds without knowing that things have changed a bit from what it used to be.

Enough on this topic bros. Except someone asks for recommendations or directions.

I bow out. We move,

NiyiOmoIyunade:
Zeal for the Lord's work ni o.

And the very faint hope that someone somewhere will benefit and all the sermonizing will help them do things right or avoid disaster.

Honestly oh, hehehehe

NEC has a YouTube handle where they constantly review codes with practical illustrations. Don't forget to search for them and see things for yourself. Some of sub codes of Code 250 illustrates grounding for transformers this code was in 2013/2013 thereabout revised in Code 690.70 with the evolution of Inverters and PVs. It became an issue for code 250s and 690s because the countered each other.

You will find out that Codes of PV groundings are constantly being reviewed after some lightening related incidents had already done damages. they will speak all the grammars to defend the former code and also issue a revised code countering the former.

Someone asked in one of the videos:
" that Codes about Earthing has been written a long time ago when we didn't have PV s, even if they existed it was not like what we have in the present scale, Are you saying we should just put our PV up the roof and hook the grounds to our house ground?"

The answer to that was:
"While research has continued in this topic, Yes you can hook them to your house ground but best practice is to rather hook them to you arrestor's earth pole which is not the same as your electrical appliances earth. Anything mounted high up on your is considered as a lightening receptor but if their Earth electrodes are less than 6feets apart, then there is no need for a second earth electrode and all Bonding must happen deep under the ground."

For those of us who have access to NEC codes articles, do yourself a favour by understanding how stuff works from your findings. So that you will not base your knowledge on personal assumptions.

FOR MY PERSONAL EXPERIENCE, I think I will follow the millions in the crowd who says while i have the CODES, I will take things a bit farther to protect my stuff. you can do your findings from videos and articles to see what people are doing in real life and not base on theories.

The image below was from one of NECs presentations. Since I have Zero Reference to my claims.

NiyiOmoIyunade:
We should stick to what is science backed fact and accepted best practice.

DO NOT GROUND YOUR HOME APPLIANCES AND YOUR PV TO THE SAME GROUND, WEATHER DIRECTLY OR INDIRECTLY. THOSE IN LIGHTNING PRONE AREAS CAN TELL YOU MORE ABOUT THIS MY "PERSONAL OPINION" Those in North America can give s of their experiences. >>>> In North America, a facility must inspection per NEC and/or applicable local codes before it is put to use and before it can qualify for insurance. NEC and local codes invariably require an equipotential bond of all Earth electrodes in a facility. The overriding goal is personnel safety and secondarily equipment safety. To alleviate some of your fears, an equipotential bond creates resistances in parallel which reduces the overall system resistance. If you had 3 rods for your main Earth and 1 extra rod for your PV - connecting all 4 rods together externally with a suitable conductor will give an overall lower system resistance than either 3 rods alone or the 1 rod for your PV - the combined system is a far more effective fault sink when all Earth electrodes are bonded together. It is not that you cannot have an isolated/standalone Earth for PV systems situated some distance from the main facility - just that you expose personnel caught between the two isolated systems to harm and the electrical code always prioritizes personnel safety over equipment.

If you have an opportunity to visit a Data Center please find out how the Earth System in the facility is built. They have Different Earths for Server Arrays, Network Arrays, Power Backup Arrays, PV Arrays, ETC I happen to have some expertise and business experience setting up backup systems, UPSs and enhanced protection for data centers - the reason why the Earth systems are separate is not for safety but rather to achieve isolation and eliminate electrical 'noise' and loops from interfering with [sensitive] equipment - the rest of the facility must still implement an equipotential bond of the lightning protection system and general protective earth.

In all forums, the subject of Earthing, Grounding, Lightning and Surge Protection is oft misunderstood, mis-implemented and the subject of much controversy. Even the electrical code sometimes seems to give obtuse or confusing or contradictory recos but there is always a way to do it right for the use case. Every facility should have a risk assessment and decide how best to implement a suitable protection scheme that mitigates the specific risks that facility is exposed to.

I happen to live seaside and very near the Lagos Lagoon - we are prone to lightning hits yet I have had an equipotential bond in place for 8 years now - at current location, I setup a Lightning Protection System using Indelec Prevectron Early Streamer 2 meters above the highest point of my house and this is bonded to the rest of the facility's protective Earth - 3 sets of 6 foot rods spaced 18 feet apart for the LPS and 3 sets of 6 foot rods spaced 18 feet apart for the general Earth - all the rods and mats are bonded together by 25mm2 stranded cable and the rods are all encased in suitable permanent Ground Enhancement Material - the PV racks and frame are connected directly to one of the rods - this is the same scheme I implement at most customer installs and with access to a surge/strike counter, I can see how many times the LPS took and safely diverted a hit into the Earth with no residual faults getting into any protected equipment - I have SPDs scattered about but not installed in my power room - my power equipment are UL listed so a bit robust for handling voltage rise

Hmmmmmm, While I might consider that you are misunderstanding my point, I stand to be corrected. However since we are talking about SCIENCE, Technically, yes they can be grounded together, But Practically, No, based on personal experiences.

It has been recently adviced that you should not combine PV/DC & AC grounds through the same earthing conductors. There are several articles covering this AC & DC Erthing Topic.

I will leave everyone to do their research about combining DC Earth and AC Earth together. While we all tend to play by the books and abey the rule of thumb, you can only improvise after learning our lessons the hard way.
We might have our individual understanding of the Electrical Erthing Rules. I recommend to the general public that
Google might be your best friend to find topics covering grounding ac and dc together.
Or you can read it up from fellow experts with sciencific backings.
https://www.google.com/search?q=grounding+ac+and+dc+together
https://www./advisable-combine-dc-ac-earthing-v-r-v/
https://samlexamerica.com/wp-content/s/2020/01/Inverters_Grounding_and_Neutral_Bonding.pdf


I rest my case. Peace

NiyiOmoIyunade:
You may want to qualify that most of these are your opinions based perhaps on personal experience as they do not conform to electrical code.

The NEC and UK codes specify a single equipotential earth bond per facility - connect all earth rods and earth sinks/sources together externally. The single combined earth enhances personnel safety (check out 'step and fall potential') and a properly bonded system prevents loops and creates one large massive fault sink per facility where the whole is more effective than the sum of its parts.

Perhaps what you meant to say is that the PV earth cable should not be connected to the main DB but rather directly to the earth rod or busbar.

A proper inverter will make a neutral to earth bond whenever mains or Gen is not available, the code requirement is to have this neutral to earth bond in only 1 single place in the electrical system at any given time hence neutral is jumpered to earth at the service entrance or supply distribution - when the mains or Gen supply fails, the inverter will immediately make the bond and guarantee that earth leakage and residual current devices will trip quickly - again these are targeted more at personnel safety than anything else and need to be used in a compatible electrical system.

I am laboring a bit to explain the backend workings here because the UPS will never make the neutral to earth bond while powered from mains or inverter and as soon as supply is restored the UPS will break the bond. I advise people to not use a UPS unless uninterrupted supply is mission critical more because it is a waste of energy to keep the UPS battery topped off and also the losses within the equipment itself.

Take it or leave it Boss, DO NOT GROUND YOUR HOME APPLIANCES AND YOUR PV TO THE SAME GROUND, WEATHER DIRECTLY OR INDIRECTLY. THOSE IN LIGHTNING PRONE AREAS CAN TELL YOU MORE ABOUT THIS MY "PERSONAL OPINION" Those in North America can give s of their experiences.

Will you spend Millions of naira in setting up a Facility only to endanger it?
While you can avoid had I known by spending less than 200K more for a proper Earth for your PV Arrays.

If you have an opportunity to visit a Data Center please find out how the Earth System in the facility is built. They have Different Earths for Server Arrays, Network Arrays, Power Backup Arrays, PV Arrays, ETC

If you are in lightening prone areas please be warned once again.

NEC and UK codes are subject to be rewritten and you will be readvised as an their earlier claim after you have fallen victim already, Check the Evolution of SPDs you will understand better.

demandtruth:

Hello guys,

Please, advise on the reliability of the following. I'm thinking of getting the system and haul into a container to Nigeria.

Description
A complete 8.4kW grid-tie solar system. We just removed this from a rooftop in Milton. We originally installed this about 10 years ago. Everything works and is fully warrantied for the next 8 years!

The cost of this equipment new would be around $15,000.

It comes with everything you need including the following;

35 Sharp 240W NDL240Q2 solar s
35 Enphase micro-inverters
Racking and flashed mounting components to install on a asphalt shingle roof.
Grounding components and wiring
Trunk cable and home run wiring.
Squirrel Guard

Install it yourself or we can quote installation also.

Complete 8.4kW Solar System - s, Inverter, Mounting
$5,500

If I understood you. Did you say $15,000 + $5,500?

Sounds penny wise, pounds foolish to me for a fairly used system. I didn't see anything about the battery ooo. Is the battery included in this package?

Source your gadgets locally and have peace.

I feel I should say something about this earthing thing.

Most people make the mistake of connecting their PV earth to the existing house earth. THIS IS SO WRONG. DO NOT EARTH YOUR PV TO YOUR HOUSE EARTH, Do a separate earth installation for your PV.

For the people frying inverters due to earth related problems. Please make sure you are not making this mistake ooo.

Finally, Before installing any inverter, make sure you take readings or the Load L/N/PE Poles there should be no continuity between any combination of these poles. If you get a reading, look for the culprit and eliminate it before powering anything up from the inverter.
If you have a UPS, eliminate it. Reason is because most UPS has a Neutral to Earth Relay that closes anytime the AC input cuts off and this is very bad for an inverter. In other words, DO NOT USE ANY UPS IF YOU HAVE INVERTER

Your earth construction must not be less than 8 feet deep also in addition to the list published above.

FEGEITOK:
So I have decided to make all my outdoor lighting smart by installing photocell sensors, so there is no need to turn them off and on, they should turn on and off automatically.

If anyone has done this before, which I believe someone has, please let me know what brand you recommend.

As for the indoor lighting, I which to install motion sensors, so if there is no one in the room, the lights should go off. So same question again, please let me know what brand you recommend.

It will make my alternative power setup last longer.

Thanks in advance.

I have visited a facility that does this, and they said that it made a world of difference to their electricity bills.

Just beginning my research on this, and I will share my findings

I actually had this running in my house, 1 Photocell powering 8x 30w VellMax Flood lights. they go on at dark and go off on day break.
I then did a little it by adding Solar Street Lights, they go on at dark and go off at daybreak too, but during rain season when the solar street lights don't get enough charge, they would turn off on or before midnight, So I changed my Photocell to a programmable timer that turns on the 30W flood lights by midnight and turn them off by 6AM..

Peace.

Elcapitan0:
Good morning guys. Great job youre doing here and thanks for all your efforts. I read almost everything here(though I don't understand all).
Please i want to ask, is felicity a good brand as i'm considering buying a 5kw lithium ion and a 5kva inverter of felicity soon. Is there another better alternative to felicity around the same price range?
And i don't know if i can get any advice if those 5kw and 5kva are too much because what i mostly want is my game console and tv with fridge and a couple perimeter lights to run for cumulative of say 6hrs. Those total load is like 1100w thoughit is only 600w (tv and game) that will take the bulk time. Lights are only on at night and fridge only during the day.
Is hybrid inverter better or shouldi go for inverter and charge controller separately?
Thanks for your anticipated response.
PS: We do have PHCN for around 6hr/day

I'm still looking for 5kw 48v inverter with the following parameters:
1. Zero load power/idle power consumption <60w.
2. Mppt operating voltage range 60v to 150v.
Multiplus Victron 5kw 48v (zero load consumption 30w/35w, zero load power in search mode 10w/15w. 30kg) with its Mppt 150/60A has all that I need but I may need up to about 2m to acquire them.
Growatt has 5kw 48v spf hvm model with built in pure copper low frequency transformer/in build Mppt with operating voltage range 60v to 145v and 150v max open circuit voltage (41kg net weight) that suit my demand as well but I'm afraid of idle power consumption as it wasn't stated in its data sheet.
Please, let me know if anyone knows any inverter that will meet the above requirements.

Please guys I will like to know or be enlightens why people the dislike of hydrib inverters (with solar charger controller and battery) don't know why most folks prefer to get individual pieces rather than going to all in one


Could it be there are not durable or what

For me I felt there are cheaper and take little space

That just my beginner option what do local man knows

Good point you have raised Bro.

I was exactly where you are some years back, wondering which is better, a hybrid or independent units.

The truth is even with higher initial costs of some brands, a hybrid inverter can pay off in the long run by giving you a solar inverter that maximizes the operations of your PV system. A hybrid inverter can help reduce your reliance on the grid, lower your carbon footprint, enjoy advanced monitoring tools, and enhance your power generation.

Hybrid inverters have the ability to work without batteries or solar s as the case may be.

Hybrid inverters are a new piece of solar technology that combines the benefits of a traditional solar inverter with the flexibility of a battery inverter into a single device. A hybrid inverter is an up-and-coming solution for homeowners who want to install a solar power system that has room for future upgrades, including a battery storage system.

Normal Inverters on the other hand, require a Charge Controller to charge your bateries in the absense of Grid power, Some Normal inverters will not start up without batteries.

Another very important difference is that Normal inverters tends to consume your batteries more than a hybrid Inverter with or without loads connected.

And the list continues. Do yourself a wider research and choose wisely..

Fellow DIYers, please maintain absolute calmness over this WhatsApp matter. It was a mere suggestion to have a Social Media Group (not just WhatsApp) and there's no need to drag it lest it degenerates into something else. Suspicons has begun to emanate already. As I always say, "Technology has come to stay, take it or leave it".

If i may itemize some of the reasons why I recommended a Social Media Group in addition to those I listed during the write-up,

> Many of us here has projects that may be beneficial to other s, which may not be properly depicted by still images but we can't showcase it because Nairaland does not have a Video Streaming API yet. Because you can't a video here.

> We are meant to patronise one another on this platform by being transparent with quality controls and pricing but some of us would quickly request that you private message them (DM) thereby exposing novices to potential danger of being decieved, scammed or cheated.

...........................................................................................................................................................................................................................................................

While the list may go on, I would suggest again that we kill this issue here and now.
Enough said already.

Abeg make una post products ooo, you will never know what someone might have been looking for to buy.

Good morning all.

I was just thinking aloud, would it make sense if we created a WhatsApp, Facebook, Instagram, Twitter, etc group solely for RENEWABLE ENERGY Platform for Nigeria and it's Environs?

I foresee a lot of benefits in doing so which includes but not limited to:

> Job creation throughout renewable energy industries.
> We can become role players in the Renewable Energy Sector and not just DIY customers of Importers.
> Ability to screen or filter out fake renewable energy products flooding our markets by boycotting them totally and advising the public on which products are genuine or not.
> Ability to have a GOD FEERING PRICES of Renewable Energy Products from importers and franchise holders.

You can add to the list.

I strongly believe that someday we should be able to compete with other countries in this RNEWABLE ENERGY as an alternative to grid power struggle. Because our sun is just burning our skins and wasting away. Most of the countries where these inverters are made don't even have up to 5 sun hours daily throughout the year. And yet we are depending on them to manufacture for us to scamper.

Let's think this through and pen down our thoughts here.

Thank you.

How effective is BMS with LA batteries and which area specifically is it needed most?
Our inverters usually take care of lvd aspects.
Most of us used battery balancer in LA batteries and do you think BMS will do better?
Waiting to see performance in review...

BMS for Lead Acid Battery Functions:

Main functions of the BMS for lead acid battery include: monitoring battery thermal runaway, open circuit, string insulation, cell electrolyte leakage, CDF discharge transient characteristic, string voltage, charge/discharge current, float current, cell voltage, cell internal resistance, cell temperature, ambient temperature and intelligent balance and estimating SOC/SOH, etc. The device automatically alarms when any parameter exceeds the alarm threshold.


Battery status monitoring and early warning: the lead acid battery management system monitors cell voltage, cell temperature and cell internal resistance real time on-line. The active battery management system carries out intelligent analysis of the thermal runaway trend of the battery, and issues early warning in time to prevent the battery into thermal runaway and protect the battery pack effectively


Battery string status monitoring: the 12v lead acid battery management system collects string voltage, charge and discharge current. It can effectively monitor the CDF phenomenon, directly display the float current and ambient temperature, and the current state of the battery, as well as help estimate battery status of charge (SOC) and health (SOH) in a high-accuracy way.

Copied!!!

Has anyone thought of Installing a BMS on Flooded Lead Acid or AGM batteries?

If anyone has a BMS 4s 48V for 4pcs of Tubular Batteries, I need one please.

Jefferyzz:
I have just one.

Who still have these Wifi Monitoring Device, I need 2pcs for Felicity Inverters.

isangjohnson:
Please, is it possible for one pv string and one battery bank to run two inverters via changeover switch?
A case of total off grid where inverter A (say 5kw 48v hybrid) could be powered in the day and switch to inverter B (say 3.5kva 48v with standalone Mppt CC) in the night via changeover switch.
POINTER: One pv string and one battery bank (Lfp) tide to the two inverters.

Get one of this and wire it up as indicated.
