Product registration

The GEN24 Plus has a verification code (V.Code) in addition to the serial number. The V.Code is intended to avoid possible misuse or mistaken use of a wrong registration code during product registration. You can find both numbers on the nameplate of the inverter. They are mainly required for product registration and to add the system to the Solar.web. Detailed instructions for product registration can be found in the download area. 


Please note: The product registration must be completed in 2 years after the registration.

The Fronius Smart Meter visualizes the energy flow of the facility. We recommend installing the Fronius Smart Meter in series to the utility meter. In this scenario the Fronius Smart Meter is able to monitor the ingoing and outgoing energy flow of the facility. 

Compatible batteries

Parallel operation GEN24 Plus and BYD Battery-Box Premium HVS/HVM

Due to the cascadability of the BYD Battery-Box Premium HVS/HVM, up to 3* batteries can be operated in parallel. The advantage of parallel operation of several storage units is that high capacities can be achieved. Thus, even small commercial systems can be realised with the combination of GEN24 Plus and BYD Battery-Box Premium HVS/HVM. You can find more information in the battery storage solution sheet in the download area.
