dickson Posted September 19, 2022 Share Posted September 19, 2022 Will a 72 volt lithium-ion battery syatem work on a 60v tap transformer of the GS 12kw and the max will be 80vdc ? My 48 volt system max out at 64vdc on a ASL9,0 PJ transformer . The PJ 10.3 controlboard will blow up the FETs at 65 vdc but the 11.1 control board will not let the inverter to even start but shut down if the MPPT charge over 65vdc . PJ no longer sell the good 11.1 control board and replace with the 11.3 control board . The 11.3 control board will blow up the FETs on all older PJ inverter and need the mainboard cable modify by the seller so be careful if trying to make older PJ inverter to work .
