Description of use
The sonnenBatterie eco is an intelligent storage system that
monitors and controls energy production, consumption, and
storage in the house.
The sonnenBatterie eco can work with existing or newly installed
PV systems. The solar inverter and eco storage system connect
to the same distribution panel. Solar modules do not connect to
the sonnenBatterie directly.
The storage system uses two power meters to monitor solar
power production and energy consumption. When production
is higher than consumption, such as at midday, the eco stores
the excess energy in its lithium iron phosphate (LiFePo
) battery

modules. When consumption is higher than production, such
as in the evening, the storage system releases the energy. In
doing so, the storage system allows you to use solar power at
night, reducing your power bill and increasing the value of your
investment in renewable energy.
The storage system also acts as a backup power supply, meaning
that if the utility grid goes out, your appliances will remain
powered.
