Dynamic Power Regulation With Several Inverters - Fronius Primo GEN24 4.0 Operating Instructions Manual

If there is no meter in the system or if a meter has failed, the inverter limits the
feed-in power to the set value.
Example: Feed-in limitation
(without consideration of the efficiency)
PV system on Fronius inverter:
Consumption in home:
Maximum permitted feed-in power of the entire system:
Case 1: The battery can be charged
Power at grid feed-in point:
Power at inverter output:
Power into the battery:
Case 2: The battery cannot be charged
Power at grid feed-in point
Power at inverter output:
Power into the battery:
In this example, no more than 3,000 W may be fed into the grid at the grid
feed-in point. However, any loads that are located between the inverter and the
grid feed-in point can be supplied by additional power from the inverter. These
loads are also compensated as required.

The power values shown are an example. Inverter configurations with power val-
ues other than those shown in the example are possible, taking into account the
criteria for this example.
IMPORTANT!
Zero feed-in is not possible when using 2 inverters.
