At 11:30 AM on Tuesday, August 1st 2017, the first AC Powerwall 2 installed in Alberta went live. Installed by KCP Energy and MPOWER Energy Solutions, this is the first of a new wave of storage that promises to allow homeowners to store the energy they create off their rooftop systems, or to begin to become self-sufficient and off-grid.
This is an AC Powerwall 2, which is a significant step up from the first generation Powerwalls. AC Powerwall 2 has a capacity of 13.5 kWh, and is fully integrated (it has its own inverter) with the grid-tied roof-top solar panels (in this case a 7.5 kW system consisting of 25 rooftop panels).
The AC Powerwall 2 full specifications are:
- Can be mounted on a wall or the floor, indoor or outdoor
- 13.5 kWh Capacity
- Provides 5 kW continuous power, or 7 kW at peak
- Rated to work optimally between –20°C and 50°C
- Covered by a 10-year warranty
- Size is 115 cm x 75.5 cm x 15.5 cm (45.3 in x 29.7 in x 6.1 in)
- Weighs 122 kg (269 lbs)
This battery system is enough to power a full evening of moderate usage, and can be easily recharged during the day. This is a solid solution for power backup (i.e. accessing power in cases that the grid-provided power is down).
KCP’s lead electrician Nick Crotty poses with the fully operational system.
