alistair Posted July 21, 2015 Share Posted July 21, 2015 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. Thanks Alistair Quote Link to comment Share on other sites More sharing options...

Jaaks Posted July 22, 2015 Share Posted July 22, 2015 That was a very quick solution. Look into (i.e. Google) the series parallel combination of batteries to calculate what you need. Quote Link to comment Share on other sites More sharing options...
