Efficiently turns sunlight into clean and green power. Our solar grid tie micro inverter employs MPPT technology, reverse power transmission, and digital control. It is designed to provide sufficient power to drive various household appliances. Moreover, it has a prolonged service life given its IP65 waterproof design and aluminum alloy structure. The first step on the sustainable energy path is energy conservation, and this inverter aims at achieving exactly this. This is a Grid-Tie inverter, which means connecting the Grid power to the "AC output" would be necessary for Grid-tie power generation. Please check the voltage is 110V or 220V as well, different options according to the Grid voltage. MPPT TECHNOLOGY- Precise maximum power point tracking. MPPT algorithm can optimize the power collection from solar panels. It accurately captures and collects sunlight, and locks in the maximum output power points, significantly increasing over 25% of t MPPT Technology..High Performance..Protective; Reliable..Easy Operation Power: 1200W/1400W/1600W/2000W Input Voltage: 20V-50V Output Voltage: 120V/230V What's in the box: 1* External On-grid Inverter (Color in Random)
