- A custom limit can be set.
- A Fronius Smart Meter can be connected to the D- / D+ connection sockets
for Modbus data on the system monitoring datalogger.
With the Fronius Symo Hybrid, any PV power that is not allowed to be fed into
the grid is used to charge the battery instead so that it does not go to waste. Dy-
namic power reduction is only activated if the battery is full or cannot be charged
for some other reason.
" No limit " - The photovoltaic system converts all the available PV energy and
feeds it into the grid.
" Limit for entire system " - The entire photovoltaic system is limited in accord-
ance with a set power limit.
Field for entering the total DC system power in Wp.
This value serves as a reference for the rule and also for failures (e.g. a meter fail-
ure).
Field for entering the max. power in W or % (up to two decimal places, negative
values can also be entered).
If no meter has been selected under the "Meter" menu item:
Max. power produced by the entire system.
If "Fronius Smart Meter" or S0 inverter has been selected under the "Meter"
menu item: Max. grid power feed
Example: Dynamic power reduction
(efficiency values have not been taken into account)
PV system to Fronius Symo Hybrid: 5000 W
Household consumption: 1000 W
Max. grid power feed: 60% =
3000 W
Case 1: The battery may be charged
Power at grid feed-in point: 0 W
Power at inverter output: 1000 W
Power to the battery: 3000 W
Case 2: The battery must not be charged
Power at grid feed-in point 3000 W
Power at inverter output: 4000 W
Power to the battery: 0 W
In this example, no more than 3000 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.
