Operation of a PV system with third-party inverters

For the operation of the Sunny Home Manager in a system with third-party inverters, an SMA Energy Meter as a PV generation meter is required.

• The power output of the inverters from other manufacturers must be captured via a separate SMA Energy Meter.

• The SMA Energy Meter must be configured in Sunny Portal as a PV generation meter.

• SMA inverters of type Sunny Boy Smart Energy and Sunny Tripower Smart Energy are not supported in this system configuration.

If third-party inverters are also used in the PV system, the SMA Energy Meter handles the recording of the generated PV energy. In hybrid systems with SMA inverters and inverters from other manufacturers, the generated energy of all inverters is measured via the energy meter since it is used as the central PV generation meter. Upon registering and configuring a PV generation meter in the Sunny Home Manager system, the Sunny Home Manager will receive the power data of the SMA inverters on this PV generation meter.

Monitoring of the PV system and the dynamic limitation of the active power fed into the utility grid are not possible with inverters from other manufacturers. In this case, verify whether operation of the PV system without dynamic active power limitation is permitted in the given country, or whether dynamic active power limitation can be performed independently by the inverter itself.
