Axpert 5kv battery selection


Recommended Posts

I am looking to upgrade my 3kv Axpert inverter with a 5kv model due to current limitation of pv array input at 600w.

The user manual specifies battery capacity of 200ah for 5kv model.

My question is whether 200ah is required at physical individual battery level or whether at overall battery bank level.

As i currently have 12v 100ah batteries need to understand if i can setup 2 x 48v series strings in parallel of 4 x 12v 100ah each with combined string capacity of 200ah.
