That first installer that gave you bill would blame you for not using the quotation he gave.
Compare his to the one you finally used and maybe you might have an idea of what caused it.

Can anyone please recommend a repairer at Arena oshodi who has the expertise to fix an Outback mppt 80a charge controller??

I appreciate all responses.

Selina gave me the number too lol
What do you think about the deriy batteries

My motto is 'the cheaper, the better'. And right now Starmax are looking good

I am currently sourcing for this extension cable.

search for powrmr on jumia, it is available there

Likely to be low voltage more than any other things like high voltage or surge. With low grid voltage, more amperes will be drawn to be able to charge your battery. This will generate very high temperature , wires will melt and shorting becomes inevitable. I once had had an inverter literally catch fire from that.

Thanks for the response

HeavenlyBang:


1. The 220aH tubular has likely been mislabeled and isn't actually 220aH.
2. Even if it's actually 220aH, when you factor in DoD, usable energy is about the same as a 100aH lifepo4 battery
3. Lifepo4 handles 0.5c charge and discharge effortlessly, tubular is more around 0.2c
4. Lifepo4 will bounce back much better after being heavily discharged. Tubular won't.

There's no reason to buy a tubular battery in 2025. Even a cheap, Grade B lifepo4 battery is better than tubular.

Where can I buy long lasting 12v 150ah or 200ah lifepo4 battery?

What can you say to this inverter from powmr

Dam5reey1:


LFP batteries should not Float.. you are using some default battery profile settings. Most installers dont change anything.

First Change the Setting 05 to USE..

Set your CV to 57.6V and FLV to 57.6V

Report back your findings

this is too high. The cells will heat up during flaot instead of resting

Can we go back to sharing tips?

I'm tired after assembling my 14.3kwh pack. Came in here to check what gives and all I see is back and forth about who sells the cheapest.

I'm here for DIY tips only and any other thing related to RE. That's all.

Anyways my 14.3kwh battery pack looks good

It's good to do it yourself. Lol

Good day boss, is this a 48v build? Please, help with a cost breakdown

Why not buy SMS inverter that is already in Lagos for 350k. Same 48v 6.2kva

JUO:

lolz , i pity those taking advice from some folks claiming Guru . the best charging voltage for a 48v 51.2v lifepo4 lithium battery is 55.2v to 56v bulk and float.

JUO:

My oga, here is my observations, Cell only Heat up if Current is flowing. At 57.6V Zero current temperature will be reduced to room temperature..

This is observation of 3 years plus..

Yes it's 48v build, 16s


Case $170
BMS+Display = $140
Cells @ $40/each *16

Transport (can't really say as I shipped it with many other things)

PowMr is also in Lagos.
Low Frequency will do him better than those FEts based SMS.

Unless you can show your own experience with how temperature increases when you float at high Voltage.

My testings shows that when current flowing is Zero, at the working range of LFP which is 3.65V to 2.5V the temperature is reduced to the room temperature.

Cells only Heat up when Charging and Discharging. Not when Current is Zero.

Good day boss, what inverter brand would you recommend for a 24v setup?

It's just a standard breaker box with the components mounted / fitted. Buy an empty box, install a rail and build yourself.
