Modes of operation
The sonnenBatterie eco offers two complementary modes of
operation: Self-consumption and Backup. Self-consumption
mode ensures that you are using the power you generated even
when the utility grid power is available; backup mode makes
that self-generated power available in the event of a grid power
outage.
Many utility companies are moving to a Time of Use-based
billing scheme, in which electricity costs more during high-
demand time periods. The sonnenBatterie eco can maximize your
cost savings by using employing “rate arbitage” — using your
stored battery power during the high-cost part of the day and
recharging from solar and optionally with electricity purchased
from the grid at the lowest offered rates.
Self-consumption mode
The following illustrates the interaction between the storage
system, the PV system, and the utility grid in self-consumption
mode:
Fig. 2 Self-consumption mode
The DC power that is generated by the PV array ( A ) is converted
to AC power by means of an inverter ( B ). The meters ( C ) and ( D )
measure the current electrical power in watts. The production
meter ( C ) measures the power production, the consumption
meter ( D ) measures the power consumption in the house.
If the production is higher than the consumption, the surplus
