FRONIUS MICROGRID SOLUTION
PV in combination with an Inverter-Charger
MicroGrids in remote areas are often powered by Inverter-Chargers. These are inverters with batteries able to operate a MicroGrid.
PV Systems with Fronius inverters can be easily integrated into such MicroGrids.
For this reason Fronius inverters have a special MicroGrid Setup that includes several functions which support a stable
operation of the MicroGrid. All functions required to ensure that the PV and inverter charger work together optimally are
pre-set in the MicroGrid setup.

/ The Fronius inverter provides as much PV energy as possible to the MicroGrid. Automatic PV power reduction is necessary
in times where the load is lower than the possible PV production and the batteries are full (or when the charging power of
the Inverter-Charger is too small).

/ Typically the power of the inverter is controlled without any communication. In this case the frequency droop of the Inver-
ter-Charger and the frequency droop of the Fronius inverter cause optimal power setpoints.
/ In addition to the frequency droop, a function for voltage dependent power reduction to prevent from over voltage caused
tripping, and several reactive power control functions, can be activated and fully configured.

/ In addition, joint system monitoring can be established
using the Victron Color Control Display (CCGX). All that’s
needed is to ensure that the Victron Color Control Display
and the Fronius Datamanager are in the same network. Once
operational, the live values are shown directly on the display.
/ Not only can PV system owners monitor their system
through the Victron Monitoring Portal, which shows the live
values, but also through the Fronius Solar.web online portal,
which provides a comprehensive range of display and analysis functions for PV system data.
/ Furthermore, the protection settings in the MicroGrid Setup
are configurable. Whether the same settings for the Micro-
Victron Color Control Display
Grid are also applicable for systems which are sometimes connected to the utility grid, depends on local connection rules.
