scottsland:
I want to setup solar system for four Thermocool Freezers with these ratings on it.
VOLTAGE/FREQUENCY: 230V ~ 50Hz
WATT/RATED CURRENT: 110W/1.2A
ENERGY CONSUMPTION: 0.77Kwh/24h

I want to use Lithium Battery
Please which inverter capacity do I need.
Also which battery capacity is needed.
And how many solar s do I need.
Please help

I'm considering
3.5KVA Hybrid Inverter
4 550 Solar s
24v 200ah Lifepo4 Battery

Will it carry the load, considering that I'm running it for 24hours

24v 4.2kw hybrid inverter
5pcs 550w jinko s
24v 280ah 7168kwh lifepo4 lithium, from me
that is all u need

TechGeek777:


Na typo, wetin mind dey reason sometimes different from wetin person dey type.

lol.. abeg go sleep small d brain don 2 work

brightk:
wat is so special abt a mac.. assuming the same hardware specification..

Smoother and well optimised environment over the windows system.

Na so them take dey chop our money 😭😭

Baba I have come to understand this thing well, same application, same system specs and the Mac handles it better, that thing na juju

TechGeek777:


This is part of the reason hybrid inverter is better.

Wait to hear the cost of getting MPPT with Bluetooth, you will see that hybrid is far better!

My system is not large, my load is under 500w so I cant be using Hybrid. That is just waste of efficiency .

easyyoke:


Omo!!!!! Bro, how many s in total(Watt) did you install for you to be seeing as much as 6kw as early as 10am

16x600W Canadian Solar s (ARRAY 1 = 8X600w, ARRAY 2 = 8X600W)
10x540W Felicity Solar s (ARRAY 3 = 10X540W)

it's a 15KWp Design and I get as much as 14KW sometimes.

Valto:
24v 4.2kw hybrid inverter
5pcs 550w jinko s

.

You've been covered

Obnoxious2001:


What type of inverter is that

Suoer 2000w/12v sachet inverter

swagifted:
omo, make this people allow me sleep with AC na

Baba, like how much do you spend on Nepa bill monthly considering that you have solar

oloet:

Smoother and well optimised environment over the windows system.

boss given d same environment hardware specs u nor go see amy diff..

Obnoxious2001:

Na so them take dey chop our money 😭😭

day guy bor understand say i de chop hardware 4 a living

easyyoke:


Interesting. What did you use to test the battery’s capacity. I have always known that these Felicity batteries must be overated. Imagine a whole 1500kwh short. What did you use for the capacity test to take the reading

I used some certain DC Energy Meter I bought from someone on this platform. Like the one attached.

oloet:

its a mindset tin bro.. so long there is a windows version otin do u

My Charge controller with this error display
The product is Felicity 120A charge controller.
I have disconnected the battery it still shows the same.
What's the possible solution please

gifted65:


Which wire do you recommend I use bro

Please look for a good installer to re-arrange that system for you. If you're not careful, the so called "installer" would collect money from you again and buy the third charge controller. This is not the right time to waste money. Please, try and remove that naked wire across the two battery terminals.

isangjohnson:

Please, drop it and let's compare with others. I have similar inverters, though from different companies and I'm yet to hook them up for capacity test.

So I did a test today with a victron quattro and got about 61% efficiency. I've done this before though and had to repeat it to be sure I was not making mistakes.

This confirmation led me to do some research and I found this....see pix attached.

In summary,these "cheap chinese knockoffs" as some people like to refer to sachet inverters, are not bad at conversion efficiency, and basic protections.

20- 40k a month...

Oshomo12:


It depends on your location, from my side, the driver couldn't move on time due to the traffic coming down.

Relax your mind, you will enjoy it.

Actually he said the BMS he wanted to use was misbehaving so he ordered another one that will be delivered on Monday.

Baba I dey laugh you like this 🤣, I was with this thought of yours many years ago too, now I know better!!!

The solar s are intentional as it carries my house and fridge throughout the day.

Is there a device i can add to view the power stats on my computer of phone? I came across this Epever device online, dont know if it would work with Felicity Charge controller!

No idea regarding monitoring

sharks776:


I am actually in the same dilemma, am in dear need of a remote monitoring device for my Felicity set up.
My set:

7.5kv inverter (Felicity)
60a cc (Felicity)
100a cc (Felicity)
60a cc (fangpusun)
12.5kwh x2(wakatek lithium batteries)
10kwh (Felicity lithium battery)

How can I monitor remotely?

I know IVEM Felicity hybrid series have a port and a dongle that you can use to stay in touch with your system remotely.

gifted65:
Please I need help.

I have 300 (3) and 250 (1) solar s
100 lead acid battery (2)
Inverter 3000w sachet

Because of my 12v, so the the installer add another pwm cc to the existing powr mppt because he said the mppt could only take 3 s.

Plus that inverter looks like a modified square wave type. If true, be saving cash somewhere to replace fridge compressor, buy new fans, and maybe repair TV.
During the day, i still don't have sufficient energy to power 120w freezer and two ceiling fans with 2 tv

The installer did this for you free?? Why are cables flying everywhere?

Meanwhile your system is too small for the load you are putting on it.

I paid o, the job is dirty. So what do you suggest I do though i like 12v because of low cost

dollarnaira:


Some of you still see simple connection like this as rocket science. If you were the one that did this it would still be better. Did I hear you say installer?

YOUR INSTALLER NEEDS 40 STROKES LESS 1

What do you suggest I do now?

Where is your location?

Your powmr is far far far better than the pwm paired along. You do not need the pwm sir.

boss na weee everybody kno reach e go talk.. u re entitled 2 ur own opinion.. so i nor go come argue with u.. me i b hardware guy dat part u nor go fit com close.. i not even de use windows regularly. My main os na linux 4 d past 5yrs..

Oh, that's ok. He will definitely deliver.

Boss, there's a clear different between a Mac and windows PC of the range of hardware. Mac is nowhere near perfect but it's a bit optimal and durable than it's windows counterpart.
Note, that's my experience.

Good Morning Everyone, Happy Easter to you all.

I recently just started the green energy journey with a few mistake and it's been fun.

I ed the Felicity crew cuz my friend was using their products but would have gone with Growatt or Epever if I knew what I know now. (No regrets).

I'm a smart home Enthusiastic and a sucker to stats and monitoring.

My current set up is - Felicity 5KVA inverter (IVPS 5048 ) + Felicity 80amps MPPT + Felicity 5KWH 48v Battery (LPBF48100) + Jinko 435w s x 6

I found a couple of ports on my inverter (RS485 & RS232), charge controller (RJ45) and batteries but cant get them to communicate with each other. Is there a way to read information from these ports wirelessly or access them remotely.

Please I would be happy to learn. My thought is that those ports arent there for decoration but there's very little information about felicity setups and remote monitoring online.

Please help me or point me in a direction to follow. Would love to read the power generated from the s and add the stats to home assistant.

If other methods suggested here fail, then you have to the Felicity factory engineers and let them send you the firmware that will enable your system to communicate. Getting them to communicate will help you to integrate the monitoring into the entire system.
Yours is 5kwh but I was told that the 15kwh works with Li-BMS RS485 protocol 12. CAN doesn't work.
I learned CAN protocol can communicate with C35D and C358 of the inverter software.
You need to know your inverter software.

This is very nice. Thanks for the analysis
