Sol - Ark 12 x2 - Absolyte GP Battery Bank x5 - 22KW Generator

[Ryan93]

Hey Everyone, looking for some direction and help!

So this is an off grid system with no solar panels at the moment - a 22kw and a 37kw generator are available

One of the generators will be used to charge the following battery bank

There are 5 - 48v Battery Banks

Each Bank is made up of 24 - 2V - 152Ah @ 8HR to 1.75V
Absolyte GP - 50G07

Here is the battery Manual

Here is the constant current charts

These battery banks will be connected to 2 - SOL-ARK12s in parallel

I understand my battery banks will have a capacity of 760AH @ 48V

I’m having trouble determining settings for Max Amps charging and discharging in the SOL Ark

attached is a picture from battery specs where it says the max charge current is 5% of C100 Rating and the chart looks to show it as 210 - 5% being 10.5A

Any help greatly appreciated!

Thanks!

Each bank is 0.05c, or 10.5a. With 5 banks, you are at 57.5a max.

Thanks rich,

How do we know each bank is .05C is that standard for Lead Acid?

Being im going to be using 2 units I’m assuming I should then have the Max Charge A set at 28.75A?

What should I be looking at to figure out my max A discharge setting?

Thanks!
