Description

The ECOmulti can be wall mounted, is easy to install, easy to program and easy to operate. With 2,3 kWh Li-ion storage capacity and a 3 kVA bidirectional inverter, the ECOmulti reduces dependence on power from the grid.

Features

Nighttime

During the night the ECOmulti is disconnected from the grid. The home is powered by energy stored in the battery. The ECOmulti will reconnect the grid when the battery is discharged.

Battery charging

The next day, when the PV array produces sufficient power to supply the loads and to start charging the battery, the ECOmulti will regulate charge current to absorb nearly 100% of the surplus PV power.

Discharging during the day

When PV output is reduced by clouds or when a power-hungry load is switched on, resulting in no surplus PV power available, battery charging will stop. Insufficient PV power will be supplemented by power from the ECOmulti. In case of overload, power will be imported from the grid to supplement power from the ECOmulti (GridAssist function), and system shut down due to overload will be prevented.

Battery fully charged

Once the battery is fully charged, additional loads (for example the water heater) can be switched on, or surplus power will be exported to the grid.
End of the day The ECOmulti disconnects from the grid about 10 minutes after PV power has become insufficient to provide any charge current. In order to prevent false disconnections due to lack of sun during the day, the inverter/charger also uses an internal timer to predict the end of the day.

UPS function

When the grid fails, the ECOmulti will continue to power the home.
