Littelfuse Solar Inverters and Battery Energy Storage Systems (BESS) can operate in both AC and DC coupled solar systems. The AC coupled solar system features two inverters, offering higher flexibility and easier installation. DC coupled solar systems have a single inverter and provides higher efficiency because the shorter cables between BESS and PV reduces losses. Littelfuse Solar Inverters and BESS components include TVS diodes, MOSFETs, IGBT drivers, fuses, relays, and more.
