Austrian inverter maker Fronius International has developed a hybrid inverter that can be used with PV and storage systems.
A prototype of the new inverter will be shown on Fronius’ stand at Intersolar in Munich.
The inverter with a grid-tied PV and energy storage system can enable households to increase their electricity self-consumption, reducing reliance on grid supplied electricity. The power supply is maintained in the event of a grid failure.
Due to its modular design, the storage unit can be expanded – and the battery retrofitted – at any time. By harnessing innovative communication channels such as web server, WLAN and Ethernet, system operators have an overview of their PV system performance constantly at hand. The device will be available in 2014.
At Intersolar Fronius will also be showing an inverter for small self-consumption systems. The single-phase Galvo inverter boosts the self-consumption element even further, because, in a single-phase household connection, all consumers are connected to this phase. The innovative plug-in card technology makes the system future-proof. It also allows functions to be retrofitted at a later date. Production is due to start in July 2013.
