The E3/DC S10 Xplus is a storage system that combines a hybrid inverter, battery and energy management from a single supplier. Capacity can be expanded later up to 47.2 kWh, and the battery can be installed separately. When the grid fails, the system disconnects and powers the whole house on three phases. With the E3/DC wallbox it charges the car with solar energy, uses dynamic tariffs without a subscription and can control heat pumps in line with §14a EnWG. The system warranty is 10 years.
