We then opted for night rate electricity and now the sonnenBatterie is the heart of the system as it maximises the PV solar generated electricity. The system is easily monitored via the sonnen app and the battery is neatly stored in a slimline cabinet in our garage.
The system was so effective we decided to convert an oil fuelled AGA cooker to electricity, thus reducing our oil consumption by two thirds. This was only possible because of the electricity distribution via the battery during the solar panels downtime at night.
In a time of great worry for our planet we are happy that the use of this system is making our contribution to fighting climate change as well as being financially rewarding.
