The Santerno Sunway M Plus 6400 is a grid-connected photovoltaic inverter designed to convert the energy generated by solar modules into alternating current synchronized with the electrical grid. Manufactured by Santerno (Carraro Group) in Italy, it provides a reliable solution for residential and small to medium commercial photovoltaic systems.

The inverter features an MPPT (Maximum Power Point Tracking) system that continuously optimizes the energy production of photovoltaic panels, ensuring high performance even under varying solar irradiation conditions.

Its robust aluminum housing, combined with passive heat dissipation and forced-air cooling, provides efficient thermal management of the electronic components, improving reliability and extending service life. The IP54 protection rating makes the inverter suitable for installation both indoors and in protected outdoor environments.

The unit is equipped with a front display for monitoring operating parameters and a serial communication interface for diagnostics and configuration.
