Hi - Advice with an Axpert  5 Kva unit - with 15 x 275w panels max - with 20 x 102ah batteries - just not getting the effiency from these batteries - should I rather split the battery bank with 2 inverters as it seems I never get SOC off one inverter - and also was not advised not to use max 60a bulk charge  - use one inverter just to charge 12 batteries and use that to run inverter 2 to run the house off 8 batteries
