Tesla Powerwall 2 batteries charged using off peak electricity (CP1139)

The project was led by NEA and North Devon Homes Ltd and had the following aims:

• Install Tesla Powerwall 2 domestic battery systems in eight socially rented homes in North Devon without solar PV where the batteries charge only from the electricity grid.
• Assess the performance of the 13.5kWh Tesla Powerwall 2 batteries when grid charging
• Assess levels of resident satisfaction with the technology
• Determine the battery performance over about a year and quantify the savings for the residents from the batteriesConsider any challenges associated with deployment and operation of the technology when charging with time of use tariffs.
