SMA Solar Technology AG
The Sunny Home Manager avoids derating losses due to limitation of PV power generation by taking
the current self-consumption of the household into account. Sunny Home Manager helps to use excess
PV power in households directly and increases the self-consumption quota as a result. For PV systems
with SMA battery inverters, the Sunny Home Manager preferentially uses the derated active power
to charge the battery.
Example: Limitation of the active power feed-in to 70% of the nominal PV system power
Due to high levels of solar irradiation, the system can currently produce 90% of the nominal PV
system power.
• At this time, 20% of the nominal PV system power is being consumed by loads in the
household. The remaining 70% of the nominal PV system power is being fed into the utility
grid.
☑ No limitation of PV generation is required.
• A load is switched off and only 10% of the nominal PV system power is consumed in the
household. As a result, 80% of the nominal system power is available for feed-in to the utility
grid – more than allowed.
☑ The Sunny Home Manager reduces PV generation from the theoretically possible 90% of
nominal PV system power to 80%. 70% of the nominal PV system power continues to be
fed into the utility grid.
Implementation of Grid Management Services via Ethernet-Based
Communication
As part of grid management services, it may be necessary to implement grid operator specifications
for active power limitation and for reactive power feed-in (e.g. the active power feed-in of your PV
system will be reduced in the event of grid overloads).
The Sunny Home Manager can implement requirements for grid management services that the grid
operator sends to the Sunny Home Manager via Ethernet-based communication.
If applicable, ask your grid operator whether your PV system is required to implement grid
management services.
