Description

Growatt 50kW inverter is a wall-mount three-phase hybrid inverter that links your solar panels, high-voltage batteries, and the grid or a diesel generator so they cooperate smoothly in one system. It has four MPPTs to handle different roof directions, acts like a home UPS with ~10 ms switchover during outages, and can run units in parallel off-grid while delivering 100% unbalanced three-phase output, useful for motors and big startup loads. The Growatt 50kw inverter is built for real-world sites, it rides through weak grids, uses smart air cooling with no power derating, is outdoor-ready to IP66, and reaches up to 98.1% efficiency with a full suite of protections.
