Frequency-Dependent Control of Active Power at the PV Inverter

If PV inverters are to be used in an SMA Home Energy Solution with battery-backup function, they must limit their active power as a function of frequency. The manner of the frequency-dependent active power limitation complies with the locally applicable standards and directives (for further information see Technical information "SMA GRID GUARD 10.0 - Grid Management Services via Inverter and System Controller").
