How Solar Batteries Work
A computer senses if you are using energy or if you are producing it. It directs spare energy into your battery for later use. Once the battery is full, spare energy is redirected and sold to the grid. Stored energy is then used at night in preference to grid power.
Can I Use Batteries In A Blackout?
This is possible with extra hardware, but rarely recommended. First you need an extra inverter component, which will isolate your home in a blackout. This is so electricians don’t get zapped when repairing the power lines. And you need to keep half your battery capacity available at all times, just in case. So most of the year you would miss out on the cost savings of your battery.
