Description
ECOmulti 24/3000/70-50 2,3 kWh LiFePO4 Biderectional converter
A simple wall mounted energy storage solution
Night time
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.
A simple wall mounted energy storage solution
The ECOmulti can be wall mounted, is easy to install, easy to program and easy to operate.
Extremely flexible
- Energy storage can be increased by adding battery modules.
- AC power can be increased by paralleling ECOmulti modules.
- Three ECOmulti modules can be configured for three phase operation.
More self-consumption, more independence
With 2,3 kWh Li-ion storage capacity and a 3 kVA bidirectional inverter, the ECOmulti reduces dependence on power from the grid.
New: approved for Germany, France, UK, Spain and Belgium: see certificates.
Note: 2x Lithium battery 12,8V/100Ah – Smart (BAT512110610), must be ordered separately.
