Maximum power point tracking (MPPT) effectively tracks and locks onto the solar panel's maximum output power.
Once the inverter tracks the solar panel's MPPT, it automatically locks onto the power output for stability.
Standard MC4 input port for simple and safe connection.
Islanding protection: The inverter automatically stops output in case of grid faults or power outages.
Built-in Wi-Fi module allows direct monitoring of the inverter's operation via a mobile app.
