Modes of operation

Note

Mode grid is not implemented yet.

Systems with grid tie inverter

Mode	Charger	Solar	Inverter
charge	on	on	off
grid	on	on	off
idle	off	on	off
discharge	off	on	on
protect	off	off	off

The mode grid is not relevant for systems with grid tie inverters, as it behaves the same way as the mode charge.

Systems with hybrid inverter

Mode	Battery charged via	Output fed from
charge	solar + grid	grid
grid	solar	grid
idle	surplus solar	solar + grid
discharge	surplus solar	solar + battery
protect	none	grid

The mode grid is useful to charge the battery from solar in winter during medium or low energy prices. Solar production in winter can usually not fully cover the energy demand of a home, but it would be economic to store the solar energy in the battery and use it when the energy prices are high.
