I'm new on MPPT SCC. Please suggest me. I bought two of I-panda Explorer-M series MPPT charge controller. I have 2 PV array (4 panel x330W per array). Each Array connect to its MPPT SCC and charge to same 24V battery bank(my battery is deep cycle Flood lead acid type). At the morning time, 2 charger show a same stage of charge . At lunch time, Battery is about 70%. The first charger is in Constant-Voltage stage (29.2V) but the second charger is Floating charge stage(27.6V). At about 3PM, the first and second charger come back to run on the same Constant-Volatge stage again. My question is Why? 2 SCC doesn't have a same stage of charge. Or do I need to have some equipment to connect between 2 SCC and battery bank to let them synchronous. I'm so sorry about my poor english.
