This three-phase WiFi Inverter with MPPT Series Connection is a device that allows us to convert the direct current provided by the solar panels of a photovoltaic installation into alternating current with three-phase output for consumption in the home, commercial premises or industry. It has a wide range and efficient MPPT (Maximum Power Point Tracking) tracker. This technology ensures that the optimum balance between voltage and current is sought so that the solar panels operate at their maximum power. The grid connection inverters are specially designed for homes that already have a connection to the electricity network. The inverter can directly deliver the energy generated by the photovoltaic panels to the home's electrical installation. At night, when there is no energy generation, the inverter takes the energy from the electricity grid. Grid connection photovoltaic systems are the ones that pay off best because they provide savings on the electricity bill with a low investment.
