Combine solar and storage.
The Bus Plus feature allows the connection of up
to four Freemaq DC/DC converters. It’s the most
cost-competitive solution for solar-plus-storage
retrofits.

3Active heating
When the unit is not actively exporting power, the
inverter can import a small amount of power to keep
the inverter internal ambient temperature above -20°C,
without using external resistors.

It also can shift to reactive power compensation mode.
