I'm shopping for a charger controller for my twelve 445W 49Voc solar panels and my 24V 525Ah LiFePo battery with a nice BMS. It's off-grid. The battery manufacturer says I should use a charge controller that supports VE.Can. is it sufficient to use a pair of "SmartSolar MPPT 250/100 VE.Can MC4"? Do I need a GX device or can I daisy-chain the charger controllers and battery BMS and be done with it?
