dollarnaira: Noticed sth about this thread. Most guys come here to lay complains and whenever different solutions were given, they no longer come here to update the house if the solution(s) worked out or not. Why?
Update on the 10kWh Sako battery issue: The customer had previously complained that the battery was shutting down at 30% capacity. Following @Dam5reey1's theory, we added 4 x 555W solar panels to the existing 3000W + installation, bringing the total to 5685W approximately 3 weeks ago. Since then, we have not received any further complaints from the customer.
At the time of the issue, the battery was going off at 25% later at 30% and the customer reported that it was no longer reaching 100% daily charge like it used to. Although i cannot confirm if the problem has been fully resolved, it appears that the increased solar panel capacity has provided sufficient charge to prevent the battery from discharging to critically low levels before the next day's sunlight. The customer is now able to maintain a healthier state of charge, and we are hopeful that this has alleviated the issue.
In addition, the sako man later replied to my messages, given the address of their service center as well as a contact person's number.
On this issue, this has to do with SOC calibration on BMS, it simply show a behavior that your Client's battery has not seen 100% for few days.
BMS and SOC is an estimate, to get more accurate SOC you must have 100% charge at least every 2 days. So your SOC will be 99% accurate.
When charging and discharge LFP the capacity in and out is always different like 200AH in and 195AH out.. BMS will calculate this wrongly overtime and what you complained about will be their experience unless they get daily 100%.
The screen below shows Inverter already cut off. At 47V which we set as LVD.. but guess what? The BMS was still showing 19%.. BMS type is the popular JK BMS so?
because client is Off grid and solar radiation was not getting it to 100% as it supposed to.

Good morning guys,please I would like to seek advice from you guys.i am not very enlighten about setting up a solar system hence my coming here for enlightenment.I want to set up a solar system on my betshop and I have a very limited budget.
The intended electronics to be powered in my betshop are,9 monitors(no c.p.u),1 laptop,2 ceiling fans(one of them is an acdc inverter fan),1 standing fan,7 led light bulbs,3 32 inches tv,3 Playstation video game and a thermal printer.
Please,how many kva system does the above equipment need.
What are the various components I need to make it work and their prices.
links of credible online vendors(not the ones that would run away with my money or sell me a bad product) that I can get each of the component at affordable prices.
I'm asking for your help cos I have a very lean budget of 1-1.2million.I tried approaching some solar installers in my vicinity but they seem to inflate the prices of most what is needed.I want to get everything needed myself then call a solar specialist to come fix them up.That's the only way I can afford this.
If a locally produce lithium battery can come into the mix for my budget range,I would appreciate it,If not I'm still ok with it.
Also my shop opens at 8am and closes 10pm business
Please your suggestions would be highly appreciated.

Please guys, can i use AVR to solve this issue i am havingon my system?
i initially had a 6kva hybrid inverter but some times when some appliances are turned on, the surge will trip the inverter off and shows error 07, i upgrated the inverter to 10kva then when such surge happens it was the battery BMS that trips off because its a 150A BMS, i changed the BMS to 200A now when such happens its starting to trip off the inverter again but now with error 09, its just all frustrating and i know i will need to get an inverter that can handle such a surge like a transformer base inverter like TBB inverter.
But i am just thinking if there is a way around it before i garther the money to change the inverter.
fuckboys: You need nothing less a 3kva solar system. About 80% of your budget is already for solar panels only.
You need like 2.5 - 3m for a 3kva setup. Continue running your gen bro, your budget is not even half of the budget you'd need.
Thank you for your contribution.
Before I came here to seek for advice ,I have already spoken to about 3 different solar technicians offline.I think I said it on my initial post.The highest figure I ever got from them was 2m.Two of them were even lesser.One of the installer was suggested to me by a colleague that did his already.So are you guys saying all 3 guys are mad or don't know their job.The only reason I came here was that I was seeing a far lesser price online for the various components than what was quoted by the technicians.
So I'm so surprised where you guys are pulling those figures from.I am not looking for the best of the best or top of the line components.i am just looking for regular and affordable.
The question is: What type of Load or appliance are you surging the system with?

Nine monitors - 500w 1 laptop - 60w Two ceiling fans - 100w One standing fan - 80w 7 LED bulbs - 70w 3 32" inches TVs - 200w 3 Playstations - 600w Printer - 50w
That's already a total of ~1650w.
Ideally you need at least a 3kw inverter. As you close by 10pm, that means you need about six hours of battery backup. Even with economic usage, you're looking at a 7kwh to 10kwh battery.
Battery alone will cost you about 1.5m to 2m. Inverter will cost you 400-500k
Since you'd effectively be pushing your battery to the brink daily, you'd need a large panel array to charge up full daily while still carrying your heavy load. At least 4000w of panels - 1m.
I don't see how you spend less than 3.5m if you want something decent.

Yes. They really just want to get paid. A setup of 2m will not make you happy. Definitely not with the load you have.

Note: is a welion 10.2kva inverter
Welion 10.2kva isn't 10.2kw from what I've heard. Closer to 6kw.
What load are you turning on? Very curious. On a 48v battery, 150A is 7500w+? I can't think of a single home appliance that draws that much power even at startup.

Objectively I don't see how you spend less than 3.5m if you want something decent.
If you want a setup for daytime usage only, the numbers would be significantly different. But still not within your budget.
You could probably set that up with a budget of 2m.
Also, I'm of the opinion that tubular batteries are a waste of money and time in 2025.
I was told it can last up to 3years.If it can,that's actually more than enough time for me to replace it,I can even decide to buy a lithium battery then.Fact is a lithium battery setup is too expensive for me right now.

How much is tubular? What is the durability? Your 220ah is 100a at 50%, unique charging profile,maintenance and pampering.
How much is 100ah lithium at 90% dod? Lifespan 8 to 12yrs without pampering.
There is only one thing I don't like about your first post. It was like you paid the group to provide answers. Your tone was rough.

i have provided systems for over 30 bet9ja shops so far.. u need nothing less than 2.5m to 3m. don't go for less to avoid had i know cancel tubular out of your mind.
here are my quotes for u
24v 4.2kw hybrid inverter with 120A Mppt + valtech Energy 24v 7.1kwh lifepo4 lithium battery=1.650m 6 to 8pcs of jinko 560w from faouni LG
There is no real reason to be considering tubular for a shop that will have you cycling the batteries all the way everyday in 2025.
Your lithium battery budget alone is already in the range of 1.5 - 1.7.
The installers you spoke with just want to install something and get some money.
The people here are not particularly interested in making money off you but that you have an adequate system and don't go back saying "solar does not work"
Choose your poison.
k2fresh: All 3 actually suggested two 220ah battery for the battery setup,they said it would hold up since the store is mostly opened during the day.

its a cafè,
ice cream machine 2 chillers 1 2hp LG black mirror AC 1 deep freezer Shawarma toaster machine (this seems to be the problem when turned on)
when the BMS started tripping off the battery plug suggested i change the BMS from 150A to 200A which i did and so far it doesnt trip off only now the inverter trips off.
At installation i installed a breaker on the output of the inverter but it kept breaking so i had to bypass it

Of course, they don't know what they are saying. Listen to the advice of people on this thread. One thing about Nairaland ehn, you will get first-hand experience of real-life scenarios with no sugarcoating.
Please, do your homework. Do you know the watt ratings of those gadgets?
Even I, mentally, calculated about 1,600 watts for you for a start. You will still buy solar panels o...and you must overpanel for it, because of extremely cloudy days...your inverter must be top-notch....then, during the night season, battery is crucial. Start counting from 5:30 pm to 10....you need nothing less than a 5/7 kWh of lithium battery that will carry you enjoyably. Then your inverter should match your panels. That's it.
? I can't think of a single home appliance that draws that much power even at startup.
cancel tubular out of your mind.
