If all you need is a unit and you are in ado-ekiti you can grab the one I used in the past

Thanks alot. Would have loved that but am in Lagos.

saint2ace:



If u're in Lagos, u can get it at arena bolade oshodi for about 1k per piece. But if u're not in a hurry AliExpress should be ur go to, as u can get various modules with volts, amps etc. Na ur money kill am.....

Thanks am in lagos

Scroll back last 15 pages, this issue was exhaustively treated



Kie kie and a few other sellers stocked them b4.
Diy plug n play display units
Aliexpress isnt so bad now, within 1 month, you should get your item

Ok thanks alot

Very few charge controllers or inverters have adjustable bulk voltage charge settings. Absorb and float are the usual settings available. Bulk voltage is handled by the internal software.

Your battery has similar charge profile with Kung Long batteries and most flooded batteries.
My recommendation is stick to 14.7v absorb and 13.6v float.
After configuring this, use a multimeter to crosscheck the voltages been displayed by cc, correspond to the preset values.
This is best done at float and absorb stages.

Adding a standalone decent battery voltage display, hooked up to each battery would also be ideal, as with this.. you are seeing how the battery bank is doing at a glance, imbalance issues are easily noticed too

Thanks for the advice. Can you suggest a place where I can easily purchase the volt display from instead of having to order it from Aliexpress which will take quite a while

NiyiOmoIyunade:
I believe you posted a VIForce 12v 150Ah battery? The label says cycle use 14.4v to 15.0v. The ideal absorb voltage setpoint is a delicate balancing act between maximising cycle life and maximising battery capacity.

I recommend 14.6v to 14.7v per 12v battery as a good midpoint to set your absorb voltage to. That works out to between 58.4v to 58.8v for a 48v nominal system.

If your batteries are AGM then a 0.2C rate is fine for a 150Ah setup. That works out to a max 30A charge current. This is another place to balance as lead acid batteries generally do better with slow charge and discharge (avoids heat).

Things like how many hours of reliable PHCN you have, how long you run a generator for daily, presence or absence of solar support will drive if you should ultimately choose 20A or 30A. If charging resources are scarce or unreliable, then go for the faster charge at 30A.

Yes VIForce battery and It has Gel written on it. Will be charging from only the grid for now. While we save up to implement solar panels next year.

30A is .2c I think that is fine, don't go above that though. As to absorb I don't have experience on that, wait for others who use that feature

Thanks very much. You have been really helpful

ojeysky:


You could stay in the middle. Bulk 59.2 while float 54.8

Thanks for the response. What should I set the absorb voltage to and should I reduce the charge current to 20A or leave it at 30A?

Good evening everyone. Kindly assist a new inverter user. Just got a 48v inverter system installed in my home by an inverter installer, but I would like to confirm the best charging settings for the batteries just to be on a safe side.
Please what should the charge settings be for the batteries in series 48v?
Bulk:
Absorb:
Float:
And which is better between 20A or 30A for charging the batteries through the inverter utility current?

modified: just incase you're thinking the batteries are installed on the floor, no there is a battery rack. I took the picture when it was just removed from the carton and placed on the floor during installation.
