Actually, you are very correct. Most 10 kVA inverters (I have 10 running in my business) only output about 8 kW. Anything above that triggers the overload alarm from the inverter.

This is my experience running a solar-based power generation and distribution system in Nigeria over the past 22 months (2-year anniversary in March 2026). We have a 400 kW solar array and a 310 kWh battery bank (8 pieces of Felicity 17.5 kWh, 8 pieces of Valto 17.5 kWh batteries, and 2 pieces of Felicity 15 kWh batteries). Daily load requirement is 560 kWh (0.56 MW), Monday to Saturday, 9am to 6pm.

1. Nothing beats efficiency. If you have AC fans, sell them and buy DC fans. Use inverter ACs, LED bulbs, inverter fridges and freezers. Use induction cookers instead of electric hot plates. The more efficient you are, the less power your panels need to generate, especially during the rainy season.

2. You can’t really have too many panels. If you have the capital, buy more panels. Overpaneling pays off in the shoulder months — April, May, and October — when extra surface area captures diffuse light and stretches production. No one beats physics: the deep rainy season will always humble you. I have a diesel generator for rainy days since my loads are constant.

3. It’s cheaper to design on a 48V platform, if you are starting from a clean sheet. Smaller gauge wires and controllers can harvest more energy from your solar array.

4. Never buy lead-acid batteries. No matter how cheap or attractive the deal looks, buy LiFePO₄. If you have ₦300k, buy ₦300k worth of LiFePO₄ and upgrade later when you have more funds. It’s like traveling by horse versus driving a modern car — night and day. The BMS in LiFePO₄ is such a leap in technological advancement that it made lead-acid batteries obsolete. Yes, it’s everything and much better.

5. Hybrid inverters are very good, if you have the funds. Most hybrid inverters support 500 V Voc, allowing longer series strings and smaller gauge wires.

6. Turning off fridges and freezers at night reduces battery drain. Using frozen containers or bags of pure water inside helps retain cold and slows temperature rise while they’re off.

Solar is not a replacement for generators. It requires mental work, calculations, and most importantly, tempered expectations. Rainy season is brutal.

Valto has visited my site and has been very supportive of my business. His customer service has been excellent since my first battery purchase.

This reflects my company’s experience. Take it for what it is — n = 1. I went with LV instead of High voltage system, it was a business decision. The Jury is still out.

Abeg what's the best SMALL freezer for my 1kva solar? I currently use Hisense inverter fridge, 60 watts. I need a small freezer with small wattage too

I have a 195L Hisense freezer that draws 800w startup for a few seconds and then drops to ~110w.

It's on for 7h30m daily (9-16:30) and averages 790wh across that period.

My bro, you say kindly? Lolz...if I like make I no do am.

On a serious note, I have done some research, I am not saying cworth is great, but from the capacity tests (usually for smaller capacity batteries) I've seen, it has done slightly better than felicity.

Please if you have evidence to dispute this based on your own research, kindly share.
Thank you

It's ok since you've done your research & are satisfied. It was just a piece of advice.

A google search would easily give these with prices as low as 9,000 naira

Thanks but these are of no help as I’m using a 24V system not 12V and these are modified sine wave which means they can’t power even an inverter freezer that consume less than 90W so they won’t work for what I need.

My boss them, please where can I get something like this, positive and negative 6mm cable with only one side of mc4 connector?

JUMIA KONGA KARA ETC

@Valto, mrreed
Please do you have JBD smart BMS 8s 100A with communication port CAN UART etc

Satchet inverter that some of us have bin using way longer than 6mths. Get original and the pure sine wave forms and u wud be fine. Odimbannamdi and Valto sell such here

oweniwe:
Don't buy transformerless inverter

Their MOSFETs blow easily after a while.

Visit any electrician/radionic shop where they repair inverters, you will see mountain of dead sachet inverters there.

Some don't last 6 months before they blow and they're over-rated too.

2,000W written on it but if you put 1,000w load continually, MOSFETs will blow.

I would rather buy tokunbo bluegate ups in good condition than buy sachet inverter again

Order 6mm cable and the mc4 from Odimbannamdi and crimp urself. Doubt u wud see a readymade one online

Abeg I fit use this connector join 2 solar cables?, I no get tools to crimp mc4 connectors abeg.

No o.
Remove the metal part of the mc4 and crimp with a plier at least it is far better than the above. Soldering it is the BEST. AND PLEASE DON'T USE THE ABOVE it is strictly for ac connection. It will melt.

Why u no wait for response before you climb up? Pele

Even if you Wan use this type, use the industrial one but the problem be say after some months, u must go back and re tighten the screws. So better to use the right connectors or solder like say u dey manufacture lead. Waste lead on the joints as already adviced that's if you fit draw power to the roof to power the soldering iron... Lol. Original lead though!

dollarnaira:

I will leave it for a week and see how it goes. My landlord don tire for my matter.

everyday I dey climb roof.

Ai said it will work but will corrode over time and that is the only issue I see there, I didn’t tape it just left it exposed like that.

If it can handle ac current of 230v, I don’t see reason why it won’t handle dc current of 160+V under 10amps.

well I don’t see reason why I need to retighten those screws over time cos there’s absolutely no tension on those wires. They just lay flat on the roof surface.

The only thing I’m scared of is corrosion over time. I didn’t tape it or anything, just left it bare like that after attaching the wires

For rust to occur, all trio of water, sun n air must be available, I would suggest u tape it all round to prevent rusting of the screws

If it's the industrial type, it comes with galvanized or brazz metal cube and screw inside the plastic so rust will be a long time issue. To reduce the rust rate, yes tape it. You should get it same place you got this.

But the screw will slack over time dew to heat expansion and reduction from current flow in the cable.

Why this massive reduction in prices of cworth batteries.
Are they good lifepo4 batteries or deep cycle batteries.

Please who has used cworth 12v 100A battery

@Valto
Why don't you use gotion batteries in you DIY packs

Where can I get good fuses for 24v system atleast 32v to 70v rating

I currently use four 300w mono crystalline panels, a 30amps pwm charge controller, a 1.6kva luminous inverter and 2 tubular batteries. Issues I'm facing is that days when we don't have light, I noticed that it does not charge well because most times I use NEPA light to charge the inverter and barely notice that charging from the solar panels itself is not optimal. I was told to change the controller to an mppt charge controller to get better charging speeds. The issue right now is I'm moving to another apartment and won't be able to use NEPA to charge the setup. What is the best upgrade I can give my current setup besides changing the batteries. I'm open to changing the panels and even getting a hybrid inverter. All input will be highly appreciated. I just need my current setup to charge well with solar as I won't be using NEPA to charge the batteries again

1. What voltage is your system?
2. What is the highest amount are you will to spend on the upgrade for panels and inverter?

24v system
I'm willing to get bi-facial jinko panels and also hybrid inverter. I can still do like 700k
I need a setup that will charge my battery well and also supply light during the day well without consuming much of my battery. Only things connected to my setup are light bulbs, 3 ceiling fans and 2 standing fans, 2 TV, one game console

Contact @ Dam5reey to get the Haisic 24v Hybrid Inverter, then try add small thing so the remaining cash can get you 4 panels (remember to connect all panels in series this time, not the way it was on the pwm).

With these you are good to go. Then later ehen the funds are available, you can then upgrade your battery to lithium.

The current setup is also connected in series. My issue now is that if I get a mppt charge controller, will it significantly improve charging speeds or I should just change panels and go for hybrid inverter. If using mppt charge controller will significantly improve my charging speeds, I see no reason to change panels and inverter.

You have a PWM and connected your panels in series? . Na you do am yourself or na installer do am? Or you dont know what series and parallel means

Na installer do am and he connected it in series. Please check my signature and send me a message on Whatsapp so you can enlightened me better as I can't seem to find your number on your profile. Thanks

Solar alone wont be enough to adequately charge ur batery cos of its chemistry. Reason u didnt notice like u said was because u had NEPA. Tubular batteries take longer to charge so the daily 3-4hrs of peak sun might not suffice.
MPPT would have to be a high voltage one which is rare and expensive compared to just getting an hybrid. The common blue powmr needs a max VOC of 105v for 24v battery which u may overshoot with ur 4 panels as one doesn't know their VOC
