There is a seller here that sells variable output voltage charger here, Valto. https://nairaland.unblockandhide.com/390522/solar-energy-complement-fta/1131#110684591

But if you don't like the charger due to cost or availability, you can buy a normal charger and get a variable DC to DC buck converter like this type from Konga with image attached below that can take a DC input (say a normal 12v charger's output) as input with variable DC output with you can use to do top balancing

Thanks a lot boss. I got my lifepo4 cells from him (valto). He's a great guy. I should reach out to him.

Thanks boss. God bless

First, is the inverter psw?
Is the inverter truly 2kva, 1kva continuous?
Is the battery amp true?
Cable is most times the culprit on a fair charged battery.

My inverter is just 12v 1.6kva brandless Chinese inverter with true 800w( same line with easun) continuous. Freezer is 115w and working on just 12v 100ah LifePO4. Even my roughly 12v 130A lithium ion battery at just 11.2v(full charge at 12.6v) powers the said load above.

So the believe that load like this requires 24v and a higher battery amperage is false based on the above load. My opinion.

Team 12v....

How much did you get the battery? I'm looking to install a small backup system with 100ah lifepo4 but I'm not sure where to get it in Port Harcourt.

In my opinion, Yes!

The risk is high if it goes through the s to the ground.

TechGeek777:


Does it mean it's better not to ground it if there's no arrestor close by?

What is the charge controller or inverter you are looking to protect's voltage?

Myself50:


Something like this

100-200k

For a simple one

Anybody has an idea of the cost of installing thunder arrestor. I think I need one

Thanks for your responses so far, but I don't understand this your statement bolded.

When is it likely to go through the to the ground?

Is it without grounding or with grounding?

Does this price include lightening protection to the ground?

Please where can i get a R48-2900U Rectifier?

recently did earthing with thunder arrestor tru a friend for 200k.. i know if its from a professional personnel i might cough out 300k.

How mismatched are the cells

Didnt Know Lithium batteries were so expensive. tot i wud get one with like 400 - 600k

You can, just depends on the kWh you are looking to get and if you can DIY.

am looking for 3-5kwh. cant do diy though.

With grounding

Cost without the trident thingy and the accompanying materials, assuming more than one pit is used for more effectiveness.

Actually, they all had same volts 3.2V~3.3V. Can't be too sure, cuz I used analog meter to measure.

Budget about 700 to 800k for 4kwh lifepo4 battery.

Why do you want to balance then

Is this a mistake? It looks expensive.

Unless you have shitloads of money to throwaway, or you are setting up a mission critical NASA office in your family house in lagos, getting all the stuff you need from usa isnt worth it...
if you insist you can get the inverter and charge controller from usa, morning star or victron...but you would spend x3 less if you get a decent model like deye or solarx in nigeria..........and upto x5 less if u get growatt/felicity /sorotec etc in nigeria.

3.2kwh pylontech lithium battery is about 1.5m naira/ 1200usd.............but you can get a whooping 14kwh decent lithium battery in nigeria for under 4m, or a little over 2.5m naira, if you go the diy-custom built models .

some tried and trusted installers are on this forum..discuss with them and have them setup ur system for you.
if you are in lekki & VI axis @niyiomolyunade is highly rated in that regard

I agree with you. It's not worth getting solar system stuff from US. Waste of money and energy.

emmaniche:

That will be hard to get such size especially when you can't DIY. The best you can do with that amount, if you can DIY, is 2kwh.

Not a mistake.

Nice, it's good to have reliable friends

Do you have the 10kw ?

I...
For my regular use I have a 3.5kva 24v Foresolar inverter. Can carry fridge and washing machine but NOT the pumping machine with other loads.

Does your Foresolar carry the 1hp pump alone?

I later did some troubleshooting about this issue and I discovered this only occur when the solar s are connected. If i turn of the solar breaker this series issue doesn't occur, but when i turn it on back it occur again.
The inverter is an Hybrid inverter so the solar is connected to it.
I can't say the power coming from the solar is too much cos they are just 3* 300w 36v solar s.
I've tried ing the technician at SMS sunmate inverter, I'm yet to get a positive from them. The only solution i have at hand now is to result to an external charge controller which is something I don't wanna do. But it's looking like i don't have much choice here.

JoeSef0:
What could be the issue here
I noticed whenever I'm on inverter and I'm using my phone while plugged in, the phone touch start malfunctioning, even my laptop trackpad and touch also malfunction when plugged in on inverter.. this doesn't happen on gen or NEPA.
Abeg who don experience this thing b4

PS:
I just noticed if i turn off extension socket, the socket light doesn't go off totally until i unplug the socket

Yes. But it will be showing a red warning light and beeping to show that it has been maxed out. So I DON'T routinely use it for that purpose. Few times I had used it to pump was in emergencies
