Hybrid inverters are combination devices that contain a solar inverter and at the same time a battery inverter for connecting a storage battery.
Single-phase hybrid inverters are available up to approx. 4 kW, while three-phase hybrid inverters can already supply up to 24 kW of energy.
Emergency power or island operation
The inverter can also be a backup power supply that provides emergency power in the event of a power failure in the house network.
This function is generally referred to as island operation. Inverter manufacturers supply devices that can handle up to six different operating modes.
