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 At roughly 30 to 40 degrees latitude (Los Angeles, Marseille, Sevilla) a 1 kWp resp. 2 kWp array will do. A larger PV array will increase feedback into the grid, but not substantially increase battery utilization and self sufficiency. Increasing storage capacity More battery storage capacity will reduce feedback into the grid and increase self sufficiency, especially during the summer season. To increase self sufficiency during wintertime both the battery and the PV array have to be enlarged. A simple wall mounted energy storage solution The...
