I suggest you do that 3.8kwh and a 12v hybrid like bread or haisic 1.5kva inverter. Better soup naim be that.

Thanks boss. Initially i wanted to go for a 5kwh 24v but because they are all over 1.2m is why i settled for 3.8kwh 12v.

But this evening i saw a deal of 5kwh 24v bread brand battery for 880k, and i want to go for it, with a 3.5kva hybrid inverter
Please is the battery size too much for the total load which is under 600 watts? And is bread a good brand? Thank you

12v 1.6kw hybrid inverter with the 12v 3.8kwh lithuim is a far better combo cheers

How about a 25.6v 7.1kwh for 820k (wooden case) or the same battery capacity in a metal case for 900k?

If you would also like to DIY, I have
REPT 280AH 82K
Eve 150ah 57k

I think it's 208Ah at 12v,either way 316ah is still bigger

Interesting, how did you arrive at this?

at this point, I think you should just go with mrreed offer then pair it with a 3.5kva inverter from bread, cworth or haisic.

And you know the bigger the battery bank, the more panels you would need to cover for it. This setup requires at least 2,500w of solar power.

i also so that post and was confused, I don't know if he has done a capacity test on it before.

Dare pulled 290ah on those battery, mine is set at 280ah.

To avoid the continuous back and forth, you should state your budget, load and required hours of running. This way you can get the best suggestions.

Please does anyone know a good solar generator I can use while saving money for the bigger setup?

Something between 200 to 300 WATT, for Starlink, phone charging and laptop?

I'm waiting to hear how he arrived at that.

You know, it'd make for an interesting read.

Hello good morning everyone.im having challenges setting up my battery settings on the inverter. It's a 5kva firman inverter with an lvtopsun battery. For lvtopsun the battery cut off voltage is 48v. Honestly I don't know the meaning of cut off voltage. However for the firman it says the battery lock down voltage is 42v . Is lock down voltage and cut off voltage the same? I don't want a scenario whereby the battery goes lower than it should as the BMS doesn't seem to be communicating

You need to check the manual for a more in-depth explanation of the lockdown voltage.

But in my own opinion, I believe you should set the lockdown to 48V for safety or precaution.

select *USE* or *USER* profile on your firman inverter , then edit the low voltage disconnect to 48v. also edit charge voltage to what your battery manufacturer specified!

Cworth panels are very good. I have a total of 4 420w which is 1,680w. I've done 1.3kwh once from the Panels with no load from the battery while powering my 1HP inverter Ac and other loads like fridge and TV.

But I wouldn't do that again on my Inverter. The panels can obviously pull more if you apply more load.

Thanks, boss

You don't need any solar generator.

For those loads, buy:

Cworth 1.28kwh battery 190-200k

Sako hybrid mppt 40a inverter 140-160k

The inverter can charge your battery with grid as well

That's 330k to 360k

Except you don't know how to calculate wattage, the load you listed cannot possibly consume 200-300w. Let's say you calculate it properly and manage to make the load 100w, The battery at 90% dod will power it for 11hrs when fully charged.

The inverter can produce 40a AC charging, which is fast for a battery of that size and should get it full in 2hrs, 30m with Nepa light.

You can decide to add one solar panel later to charge it with sun. A CWorth 420w panel is 89k or thereabout.

At 5hrs peak sunlight, this will get your battery full in 3hrs-4hrs, depending on the sun intensity. Also with that solar array, your battery won't get discharged while carrying load during the day. The inverter can power your load directly without feeding from your battery

Thanks for the feedback unfortunately I can't seem to find Lvd on the manual just the battery lockdown voltage which I'm not sure what it means

Make COU or cut-off Voltage to 48V if it can go that high, but if not, make DTA 49V.

while CU is 55.2 and FLU is 54 ...... This is a more conservative battery parameters for 16s LIFEPO₄ Battery

This brand new JA 430w is broken at the top left corner. It's bifacial

Is it a good buy? Unbroken is 118k

This is 80k

Buy cracked pv at Ridiculous price.
This price is 38k difference unless it is sold at 40k.

There's two actually

The 2nd one is only cracked at the back since it's bifacial. The front is clean no crack

Do you Reckon it's a good buy?

DIY with smart BMS is better. Forget all those brands of batteries

Only a good buy at 10k

So by next year you'd replace it.

Cheers.

Better to buy the one with crack at the back for ₦30k.
Crack in front no work at all.
Cheers.

It is actually, Joke apart.
Installation surface into consideration.
But try bargain 50 or 60k.

Dem later collect 55k

The back crack only affects the outer layer glass of the back. If you rub your palm against it, there's no glass pieces tearing into your hands, meaning it's line crack. You'll only feel the crack if you rub the tip of your finger nails against the lines.

I only bought the one with the back crack

Thank you. I have set up the parameters as suggested. Much appreciated

Super deal.

So does it mean SRNE and cworth batteries and the likes dont have smart BMS?

Mykcool:
To avoid the continuous back and forth, you should state your budget, load and required hours of running. This way you can get the best suggestions.

Budget 1.8m.
Total load 528 watts.
Atleast 8 to 10 hours backup after sundown.

I was asking if the 5kwh is not too big for a total load of 528watts, and mrreed is even coming up with 7.1kwh. And i am not doing the DIY, thanks
