power function IMPORTANT! In emergency power mode, an increased nominal frequency is
used in order to avoid parallel operation with other generators.
To ensure fault-free regulation, parallel operation of several batteries is not per-
mitted.
When the hybrid PV system is equipped with all the available features, the invert-
er can:
- Feed energy into the grid
- Supply the devices that are connected to the PV system with power in the
event of a power failure
- Use any excess energy to charge the battery.
