you need a hybrid inverter

kewhos:
Good day everyone, please I’m looking for a good installer in Warri. Kindly indicate if you are an installer in Warri or recommend me one

Chief greetings reach me out if you have not gotten anyone yet.

Good day my engineers and solar tech savy people on this thread, please i need a little guidance from you guys.
Can one 24v 2.5kwh 100ah lifepo4 battery do the same job of two tubular batteries of 200ah or 220ah for solar backup when the sun is down?
I would have gone for the 5kwh lithium ion but the prices are too high, and i want to join the lithium gang so please your input is needed.

And please also advice if a 2.5kva or 3kva hybrid inverter will be better for the lifepo4 24v 2.5kva battery.
Its to power the following items:
1). Freezer: 105 watts
2). 55inch tv: 135 watts
3). 32inch tv: 58 watts
4). Sound bar: 140 watts
5). 2 fans: 45 watts each (90 watts)
In total: 528 watts.
For the fans i am planning on changing them to solar fan, i already have one, thank you

Never ever got more than 1.3kW from a possible total of 2.1kW.

Today I understood why.

1 of the 3 panels was not connected.

I have gotten 6mm wire to sort it out.

I totally recommend FY panels.

Will get more ASAP given that the test results are so good

My friend assisted with the connections, I did not thorughly inspect the final job, by that I mean the connections at each panel, I just saw that wires were apparently connected to all three panels, but one wire from Panel A to Panel C was not connected (the missing connection that I found out today)

iraybuju:
Thanks very but it still did not work, is there a way to factory reset it ?

iraybuju:
The problem is that it doesn’t even show the numbers so I can input, if I press down or up arrow key it shows I’m imputing something but I can’t see what going in nor do I know what I am pressing, it just shows asterisk blind figures so I don’t know what’s going in

kewhos:
Done that, please check

Trippledots:
Also is this bi-facial?

Trippledots:
Hmmm...so they are all in parallel config?

Trippledots:
How though? The installer forgot to connect it?

AndroBlaze:
Like has been advised severally on all knowledgeable sites about lead acid batteries, if you want it to last it's average life of 3-4 years, don't do past 50% of capacity. So with the options you mentioned the regular power from the 2 batteries is either 2.4- 2.6kw. As for the lithium you can drain it to 95% of its rated capacity for the next 5 years and more without noticing much difference in its performance.

Now, not sure if you intend to use all the appliances you mentioned at the same time. If you do then it still makes more sense to buy lithium as lead acid only appreciates being drained slowly and not being drained in a period faster than 10 hours. In this case, that means on your lead acid bank the maximum load you should do at a time is 480-520wh (depending on which type you get). Also the 10hr rule I gave you is for top LA batteries, most of the standard ones is actually a 20hr rule, so that cuts your maximum to half 240- 260wh. Lithium is not interested in these rules, just don't exceed what the BMS can take and you will be fine.

As for the options for the inverter, as far as I am concerned, it's six of one and half a dozen of the other. Just pick the one with the better build or price, whichever is more important to you.

Lol boss, omo this plenty technical assembly was not straight to the point for me o.

I just wanted a yes or no to 'can one 24v 2.5kwh 100ah lifepo4 battery do the same job of two tubular batteries of 200ah or 220ah for solar backup when the sun is down? Since i cannot buy a 5kwh lithium battery alone which is over 1.2m to 1.4m. Because i dont want my total budget for the setup to be over 1.8m.

And for a total watts of 528, what inverter is best to go with the lifepo4, is it a 2.5kva or 3kva inverter, thanks boss.

HeavenlyBang:
Yes, a 2.5kwh lifepo4 battery is better than two 200aH tubular batteries.

You can buy from Mrreed or Valto. I bought a 4kwh battery from Mrreed for someone last month and it's been working great without issues so far.

cutefy:
He did justice to your question and from his explanation, you should understand better that 'Yes' is the direct answer to your question

Thanks @ Dam5reey1, I have received the Haisic stackable system (4.2kva and 8kwh lithium battery) with the breakers.
