1Effective Tracking: MPPT (maximum power Point tracking), effectively tracking and locking the maximum power output of the solar panel. When the inverter tracks the solar panel's maximum power point, it will automatically lock and have a stable output 2Easy Installation: Standard input port, easy and safe installation. Integrated AC output port. Pure sine wave output. Historical (daily, weekly, monthly) power curve 3Anti Island Protection Function: When the public power grid shuts down or fails, the inverter will automatically stop output. Over temperature protection, short circuit protection and overload protection 4Waterproof Design: With IP65 waterproof function, waterproof effect is remarkable, even in the event of rain do not worry 5Material: Solar smart micro inverter aluminum alloy, ABS material, strong and durable, the use of long life, not easy to damage
