Fronius and Victron Energy have aligned parts of their product ranges with each other as part of a partnership agreement. The electricity generated by Fronius PV inverters can be easily stored in batteries with the help of inverter chargers and charge controllers from the Dutch energy specialist. A continuous, stable and grid-independent power supply can thus be provided for small residential areas using photovoltaics.
A continuous power supply is not a given, especially in remote areas, where the public grid is often unstable or in a poor condition. A photovoltaic system with an integrated Fronius inverter provides a continuous supply of electricity, and most importantly, is independent of the public grid. The energy generator is connected directly to the microgrid – a regional, self-contained power distribution network.
Both companies placed a great deal of emphasis on fail-safe operation during the development of the joint solution. “If the load is less than the maximum capacity of the PV generator and the batteries are already full, automatic power reduction is required,” explains David Hanek, Product Manager at Fronius. “Otherwise, the system will switch off due to overvoltage.” To prevent this, voltage-dependent power reduction and reactive power regulation functions can be activated.
