The Sunny Boy Smart Energy is the ideal gateway to an all-round energy transition in the home. As a PV and battery inverter in one, it ensures a reliable and sustainable supply of energy. Thanks
to the integrated secure power supply function and an optional battery backup function1), it will continue to run even if the utility grid fails.

Three MPP trackers allow varying roof orientations to be incorpo- rated into plans for solar power production.

The hybrid inverter offers very fast charging for connected batteries and makes the most of days with few hours of sunshine.

Heat pumps, charging solutions for electric vehicles and smart energy management can be flexibly integrated into the energy system at any time. This means greater independence from rising energy costs and conventional energy supplies. With the Sunny Boy Smart Energy, users can expect the high standard of quality that comes with a product made in Germany.
