Nteogwuija:
Good evening, guys.

So I have a 12v 1.5kva setup(1.5kva Sukam inverter, 220ah tubular battery, 40amp mmpt CC, and 700w ).

The tubular battery if fully charged can't power my 50inch TV for 6hrs, considering that one is suppose to use about 50 to 60% of ba3 and then the safety on the inverter turns off the system.

I need an improved backup system still on 12v, and I'm considering selling the 220ah ba3 and getting a lifepo4.

My questions are;

Can I use my current Sukam 1.5kva inverter to charge a lifepo4 ba3?

Secondly, what capacity of lifepo4 would be a proper and highly improved replacement for the 12v 220ah tabular?

And lastly, would I be needing to add to my 700w solar should I get a lifepo4 ba3?

Thanks for your responses in advance.

Your charge controller is what does the charging, not the inverter.

Check the manual of your 40A MPPT to see if it has lithium charging and/or editable charging parameters.

2. Considering DoD, a 100aH battery would be about the same as your 220aH. Slightly worse in capacity but you make it for it with higher charge and discharge rates. Assuming your TV is the only load you have, a 100aH lithium battery should last for about 8 hours.

3. Keep your 700w . I don't see much economic value in buying another 700w for a small setup like that, and buying a smaller to add would just mean you leave a lot of power on the table.

He needs both to charge the battery.

This is how my neighbour lost 3 of his 280ah cells three years ago. He bought Daly BMS (300A) and was too lazy to connect it. Ended up overcharging his batteries with 3 cells swollen so bad he was afraid to use it. The charger he was using was a 48v 3000w Huawei rectifier. It was a tough lesson well learned

Always use a BMS. Or get ready to either rebuild a house or buy new cells or both. The choice is yours.

Always use a BMS for charging. You don't have to use a BMS for discharge. In many cases it is redundant, it can even limit your battery performance.

He needs both to charge the battery.

Explain, boss.

He was asking if can also use the inverter's charging profile from grid to charge a LifePO4 coming from Tubular.

I have a 65w table top fridge that I want to run all the time(if that's possible). I don't use the TV always.

What type?

Good day house, please, what is the best felicity MPPT settings for 12v 100ah Nigerian build Lifepo4 battery with 100A bms?

Happy new week everyone.

I'd appreciate advice on my intended setup.

Current appliances are:
– One LG 2.5HP or two 1.5HP dual inverter ACs (all on gen mode)
– 1 LG smart inverter compressor fridge
– Water dispenser
– two 65 inch TVs
– Starlink router + internet access points
– Home theater system
– Lights and fans

Estimated total load is ~4.5kW, but I'll be moving to a larger property soon – so the system should handle increased load in future without major upgrades.

Parts I'm considering:
– 1x Growatt SPF6000 ES Plus (6kVA hybrid inverter)
– 1x Felicity FL-LPBF48300 51.2V 15KWh LiFePO4 battery
– 10x Jinko 620W s from Fouani

My questions:
– Does this setup make sense, or is there anything obvious I'm overlooking?
– How much should I budget for a complete installation?
– Can anyone also recommend a reputable installer they've personally used in Lagos? Lekki axis
– I see vendors selling inverters and batteries here on Nairaland. Is it advisable to buy from them vs from known distributors? I'd rather pay more for peace of mind and warranty, but I'm open to cost-effective alternatives if they're reliable.


Would really appreciate insights from those with more experience.

Thanks in advance!

Hello My Ogas,

Please i notice when i use my inverter to power my Fridge , it light of the fridge flicks abit, not so much but its noticable.

But with nepa, no flicking is observed, what could be the issue, i use same inverter with all the appliance in the house with no issues at all.

Can any one help with what could be wrong?

Is your inverter pure sine wave?

Can you check if your inverter produces pure sine wave current. Some inverter produced modified sine wave & that can cause this kind of flickering on the refrigerator from my experience.

How do i do check this?

Is your inverter pure sine wave?

From the best of my knowledge, it is as i use it with my inverter freezer with no issues at all. i dont notice flicking on the lights. And with my fans no noise or humming sounds.

At the time of need, I had someone come over with an equipment and he said that sachet inverter wasn't pure sine wave. From your other response it appears yours is pure sine wave since it doesn't display the tell tell signs of an MSW. Is your inverter sachet inverter? What is the continuous Watt rating?

Its a Genus 24V 2000VA inverter

I dont understand what you mean by continuous watt rating though.

Just wondering too.. With this Band A something, thought i would be able to use it on my inverter and mehn it is well oo.

Am on standby for suggestions

Thank you
