Why choose a Systellar MPPT controller?
Our synchronous-buck and interleaved MPPT designs reach up to 98.8% conversion efficiency, support panel strings up to 750V Voc on the high-voltage models, and let you set the exact charge profile for LiFePO4, Li-ion, lead-acid and Ni-Cd in the field. Built-in protections cover reverse polarity, overcharge, deep discharge and short circuit. For inverter-based homes, the Gen6 adds a built-in Solar Management Unit so you can add solar without replacing your inverter.
