2023 Upgrade 400W Micro Inverter Solar Grid-Tie Controller — MPPT, Waterproof IP65, DC 18–60V to AC 120/230 Auto Identification, Wide Usage

Designed for easy system expansion, this 2023-upgrade 400W micro inverter lets you increase solar array capacity without replacing the main inverter — the inverter’s nominal capacity does not limit further additions and installation is simplified. Built-in MPPT (maximum power point tracking) ensures each panel operates at its peak output, reducing performance loss from shading or other obstructions and boosting overall system efficiency. The inverter accepts DC input voltages from 18 to 60 V; operating at lower input voltages helps protect both the inverter and the rest of the system for safer use. Unlike conventional string inverters that create UHV from series connections, this micro inverter architecture avoids those very high voltages and therefore offers a distinct safety advantage. IP65 waterproof protection, grid-tie capability and automatic DC-to-AC 120/230V identification make it suitable for a wide range of installations.
