What are the benefits of battery backup?
A battery storage system lets you store electricity to use whenever you like – in case of power outage or to avoid paying peak rates.
A battery storage system has two primary benefits – outage prevention and bill savings. If you have solar panels, you can store surplus electricity and save even more on monthly bills.
- Energy savings: Homeowners with solar + battery systems can typically lower their electric bill by 90-95%. In the case of a standalone system, you'll still be able to save on your bill by charging your battery during off-peak times, then switching to backup power when rates are priciest, typically from 4pm to 9pm.
- Backup power: In the event of an outage, your battery will automatically disconnect your home from the grid and start powering your appliances. Depending on your energy usage and system configuration, you'll be able to rely on your battery to power your essentials for 1 to 3 days.
- Lower CO2 emissions: Producing and storing electricity that comes from a renewable resource lowers your household emissions by about 22% a year.
