IMI series inverter Using IP65 waterproof streamline design which effectively prevent rainwater on the erosion, built-in high-performance maximum power point tracking MPPT function better to track changes in the solar luminosity and control different output power, effectively capture and collect sunlight AC electric power transmission using the reverse transmission technology. The inverter output power can provide load priority use, extra electricity to the grid, efficient use of the inverter to the power emitted, electricity transmission rate of up to 99percent . The convenient way to directly scan the QR code to connect to is a major feature of it, allowing non-professional users to monitor the power generation system data in real time through a smartphone.
