Y'ep but sometimes the thermostat seems to get stuck on the wrong temp. in some parts of the world. 😳
The electric company is now pushing for everyone with solar panels to buy the back-up batteries. They want the homeowners to store juice so that when the grid is under high usage, they'll be able to pull from your system when needed. 🙄
Supposedly they pay the home owner for the kilowatts used.
The homeowner foots the bill for the unit & installation.
