Where can I get brand new Lifepo4 battery from
100ah preferably

Penuelseun:
you can get the cells and assembly yourself, but better you get an active balancer with it to support the bms, I also think you are better off going for a 24v setup and they have a wider voltage range

Valto:
probably on the fence .some landlord na werey, one said u are free to install on the roof, but will not be allowed to remove it, even if u are packing out, it becomes landlords property.

How much is the 300watt

DolbyDigital:
Hello guys. Please help me out. (I am willing to pay consultation fee)

My MPPT ratings is this:
Max Current: 40a
PV input power
12volt system: 12v 540 watt
24volt system: 24v 1080 watt
36volt system: 36v 1620 watt
48volt system: 48volt 2160 watt.

I want to use charge my double 12volt 200ah batteries. To follow the specification, I arranged with a someone to help me get a 600 watt solar panel. Because 600watt solar panel won't come in 12 volts. I paid for four 12v 150watt panel.

When the panel was delivered, it was a double 24v 300 watt panel. I insisted on returning it but the seller was aggressively convincing that the specs won't matter. 24 volt will still work and all that.. blah blah blah but I gave in sha.

Since I have connected it, I feel like the charging is not working to its maximum. The charge controller specifications is 24v 1080 watt but I am using 600. Maybe that is why it is not working to the maximum.

So far, the highest I get is 240watt an hour when the sun is at its brightest. I don't know what to do.

I don't know if I should sell the panel and but another set of four 12v 180/150 watt and sell this one.

Or I should buy another inverter which is 24volt and wire my battery in series.

Or I should buy another MPPT charge controller?

Please help out.

That is the issue with li-ion cells in the 3s config, they have a voltage range of 9v to 12.6v which most 12v inverters struggle with, 7s 24v config is the sweet spot for them. Your ups is configured to work with lead acid battery whose voltage range is higher, 11.5v is the cutoff voltage of most ups which in a lead acid battery is around 70% dod
You are better off going for a sachet inverter that can go as low as 10v or boost the voltage to 13v with a boost converter which is not that efficient

officialfestus:

CockPit:
God bless you too. I am glad I was able to be of help.

GuestJoe:
Go and buy SPL fans. They are 17watts and they are good too. Ask your solar installer about SPL fans.

They have ceiling fans too that are energy friendly and efficient

I bought a rechargeable fan some months again and was happy with the outcome. It can go more than 12 hours on low speed and 6 hours on medium speed tested when I newly got it.

But since we normally have electricity I hardly use the battery power for long. Always in the light power while the battery takes alot of hours to fully recharge even if you uses it for few hours. The fan is always on charge as a permanent room fan as I prefer using it than the ceiling fan.

Within 3-4 months the battery begins to charge faster and discharge faster too. The low speed can barely go 3hours and medium speed just above 1 hour.

At the rate the battery become faulty its doesn’t even worth replacing it.
