Already got the 10kva cos prices keep going up. Was advised to get it now before things really get out of hand

If I may ask sir, what type of inverter is that?
The dynamic dollar rate may still get you on the way, if you're not also buying other items on time Lol.

Why and how did you arrive at the conclusion that u need 10kw inverter??

quack installers, with moronic quotes is to be blamed sha. 10kva inverter on top 4pcs cheap fake capacity 250ah lead acid gel battery(actual capacity might be 150 to 180ah). if u calculate inverter idle current draw@ batteries 50% DOD, then battery might run down in 24hrs, without any load on inverter.
with his load, he needs
5kw hybrid inverter
6000w of s
28kwh lifepo4 lithium battery bank.
thats approximately 7m budget.
otherwise big tears is loading...

E will b charging 2400w daily. If he's doing 50% dod. 800w is truly not enough considering the fact that other appliances will b on during sunlight. But if he's on a tight budget. That will do.

isangjohnson:

Though the day time loads aren't stated but charging 5280wh tubular battery bank to daily float from 800w pv will be difficult unless grid will give 70% while pv will give 30% . If not 1600w pv should be considered.

U will need to check d name plate of the freezer. But my guess is 130w. My 160l freezer is 109w
Pumping machine is how many hp. I'm using 0.75hp n my 2.5kva displays 53% usage wen it's on.
Wat kind of fan
Check ur tvs back but Im guessing like 100w. Mine is 74
For the lightening.. u might decide to buy 5w bulbs if ur current type is consuming more
Check ur laptop adapter for d wattage. If u can't figure it out. State d model.
Wat kind of washing machine. Check d name plate.
In my honest opinion. Ditch those lead acid batteries for lifepo4. U wont b spending up to 100k more for more power n durability n longevity. U won't b spending up to 1m even if u decide use lifepo4 with 1200w s sef

Current load is 1.5HP AC - the power saving type, 240W Gaming Laptop, 100W 50" TV, over 20 15-30W light bulbs, water heater.
Additional TVs may be added in the near future, at least 2 DC standing fans, and possibility to add, 1 or 2 more ACs. Electricity is fine for now but certainly not sufficient hence the few batteries and poor but cheaper battery choice

earthrealm

Load will increase drastically by next year by 100%. It's more of a futuristic planning with limited budget for now.

Current battery totals about 10kwhr. It's a temporary solution b4 an LiFePo4 pack hopefully. Already saved your for that purpose.

It's a Solar inverter (not hybrid tho)

I don't really know how you'll get the needed help in this faceless forum, if you're not dropping complete information.
Which one is solar inverter?
I was actually asking for the name of the inverter you've already bought so we could know the next advice to give as the mistake has already been done.
You may be testing public opinions here...
Whatever is the case, this is a learning platform where most of us including myself came to seek help/advice often.
I wish you all the best.

Would love your inputs

The s are insufficient
I doubt the charge controller is suitable, especially for the type of batteries quoted.

emmy9500:

did the installer tell you that the setup would power these or you're the one assuming?
Because your batteries are already dead, even before installation.

AinsSama:
Hello house. So I got interested in getting a high wattage solar inverter due to my future needs/load - a 10kva 48V one. I don't want to buy anything less due to the natural tendency to keep upgrading. Current budget will be able to make that possible along with a maximum of 4 350W s and 4 12V 250Ah deep cycle gel batteries (already got the s, batteries and inverter) along with a 100A MPPT charge controller. Couldn't afford the lithium ones for now.

Problem is I don't know the voltage of the s so I'm confused on what arrangement to go with for a start. Series or parallel? Especially knowing I'll be adding to those s with time. From what I've read so far on the thread, I deduced the batteries should be connected in series to get that 48V.

PS: I'm not DIYing, but hiring some engineers who have just a little bit of experience in solar installations. Hence the questions.

With your batteries, you should be talking about minimum of eight s, and you already said maximum of four?

emmy9500:


My oga, please ignore the cost cutting

As much as I wan cut cost, I also need durability even if it will cost more….. durability always pays in the long run

Which charge controller do you advice I get

If you're really talking about durability, you may have to double the amount on the quote or increase the budget while taking off some load from the list for now, especially those machine - machine loads.

AinsSama:

If you have the money, I'm not sure these loads are actually for lead acid batteries, that's not saying lead acid won't work but you'll need lots of space and babysitting for DOD, balancing etc.

Tsuccesssquare:
Someone mentioned there are Qasa standing fan of just 5watts selling for 33k each. Please are they durable?

Would also appreciate any recommended solar flood light products.

Thank you.

Standing fan of just 5watts ?

Kabawhat:
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

Separate inverter, charge controllers have their advantage over the all in one especially when there's a malfunction. If the all in one has a fault and is decommissioned for repairs, your batteries are alone till the repair is completed unlike if either the charge controller or the inverter in the standalone setup is faulty, there's still a charging source available.

Juror:


did the installer tell you that the setup would power these or you're the one assuming?
Because your batteries are already dead, even before installation.

Haha. People get mouth for this platform oo. Lol...
Dead even before the installation

jonescosmo:


This stuff is huge man. Height 77cm by Width 47cm by Dept 30cm. Take your tape and draw up this size and see what it looks like.

I should have opted for 2x 8kw

Over big dey worry this 16kw

Boss of the bosses, we are still waiting for the picture for your new setup of your new 16kva inverter. Motivate us boss

Please guyz, I have my uncle at Finland whom called me asking me for USA (non China) Inverter... He wants to which to buy and include in his containers...
Please someone help with few names. Especially the best...

A church member reached out to me to come check out their solar-inverter installation. The wife said the batteries don't last anymore and that the inverter spoilt and the guy that installed it initially took it out for repairs.

My first thought was, well, let me recommebd a budget 24v inverter you could use then. It was a no-brainer. I reached out to Valto for current prices of his inverters and funds was about to be disbursed, but on a second thought, I decided to first work with the spare transformerless easun12v inverter I had. Besides, that should give me an idea on how weak the batteries actually were.

So I separated both batteries and hooked them up individually to the 12v inverter and they observed how long each of them lasted on a fixed load. Expectedly, one was failing faster than the other. After that, I decided to combine them in a parallel 12v to see how long they would last together.

Brethren, after the whole connection, inverter refused to come on. No sign of life at all in inverter. Confusion hold me...lol

When the husband saw my confused state, he began to open up. He said that is the 4th inverter that is spoiling on the set up. He began to blame his wife for not supervising how the set up is used at home. That they put on even pumping machine on it and all. That the one at their school hasn't spoiled, etc etc. I doubted that overload was the cause of the damage, coz the inverter has overload protection.

Then it occurred to me that someone here once had a similar issue and the possible identified culprit was the earthing connaction. So I asked the man if his earth connection was properly done, he then confessed that he doubted so. That there was a way the house was wired and all of that, and that he would call his electrician to inspect it.

My point is, people/clients can so withold relevant information eh! Imagine if i had gotten a new inverter, and this issue happened. Probably, I would be dragging the seller by now. Sad situation.

Please, how can this be resolved? Is earthing really the issue and what can we do? Also, what is likely to have spoilt in the inverter? I just weak...something wey I no even charge them, based on hobby and relationship waka, i now lost a precious inverter...

In addition to the numerous sound advise you have gotten from experienced folks, get an MPPT solar charge controller. You are investing a lot to use that PWM your installer is recommending.

Thankfully, I have a budget MPPT CC for 63k.

Also, please avoid lead acid batteries. Stick with lithium batteries

Greetings house.
Please I need advice for what to get for a shop on low budget. Load is,

60 watts oscillating fan
40(4×10) watts bulbs
100 watts(not sure) tv
Personal phone charging (5 pieces).
All will be on for duration 8.00am to 7.00 pm daily.

Will these items do the work?
100 watts
10a pwm charge controller
40ah lead acid battery
300a msw inverter.
As an unrepentant DIYer, I am setting it up myself
Thank you.

PS: If I opt for li-on battery, it will be like how much for it?

emmy9500:

Which charge controller do you advice I get

Better, you are now talking my language. If anyone wants to do solar, one basic thing is: how do I get it right! Ignoring this is a very big disaster on your part.

Since you are using a 24 volts system. Kindly get a fangpusun 50a mppt or Epever 40a mppt(no 50a). Stay away from PWM, except u really know what you are doing.

toyeoye:


Na advice be this or you're making jest of him? I hail o

My brother, you think I am making jest of him? I was very angry with the post! Do you think that even with his stated budget, such money is easy to come by with the current state of Nigeria's economy? If u have a cut cost mentality in solar, u loose every penny spent in months.

AinsSama:

Maker is Sunfield. Same manufacturer as the s.

With a 150v voc, do 3 in series.

You can see that your 4s in total is grossly inadequate! As pointed out by @earthrealm, all he mentioned are valid. 10kva has a lot standby consumption! I will do a minimum minimum of 9 of 350w s. I prefer 12 minimum anyway. 4 batteries can never cut it.

Prince3:

Hahahaha, I will do the installation from friday because of work schedule. By saturday everything should be done and I will update us.

Also had tha t issue sometime ago, 2 inverters died within 6months, after the 2nd death i told owner to do a new earthing just for the inverter, as i suspected the shared earthing had voltage leakage....going to 6months now everything is working ok. consider doing this or dont hook up to earthing at all and observe

I complained about my hybrid recently

It started misbehaving the moment I connected it to charge from grid.

Since I removed that it has been okay.
I'm suspecting earthing too because when it was connected the body was "shocking"

These are American inverter makes: AIMS Power, Vertiv, Magnum, MidNite Solar, Morningstar, Outback, Renogy, Sol-Ark, Tesla, Caterpillar, GE Solar Inverter, Innolia Energy, Rich Solar Inc, etc

You can also try SMA (German) or Victron Energy (Netherlands)

Important Notice: Let the uncle the output voltage is 230v and not 110v when buying an American made inverter.
