250K-M12 / 300K-M12 / 350K-M12 / 350K-M16

Solis' largest three-phase, 1500 VDC PV string inverter has 12 MPPT (250, 300 and 350) or 16 independent MPPTs (350K) options that allow for great redundancy in larger systems. Redundancy through a distributed method supports overall system uptime. With our high current rated DC inputs, systems can realize full capacity as well of their PV modules. Our system supports ease of installation with MC4 connectors, while maintenance is streamlined with SolisCloud and advanced, remote monitoring. Our fuse-free design supports long-term reliability, further enhancing the overall return on investment for large systems.

Three Phase Grid-Tied Inverter

Leading Features
