Learn about your different backup options:

  • Portable Battery

    Smaller than a briefcase and rechargeable from a wall socket, a portable battery packs enough power to keep your electronics charged during a short outage.

    Portable Generator

    In the case of emergency, wheel out a portable generator to power some of the home’s largest and most essential appliances. To keep things running during a multi-day outage, make sure to keep a supply of extra fuel.

  • Graphic illustration of a standby generator

    Standby Generator

    Permanently installed on the side of the home and generally run on natural gas or propane, standby generators provide 24/7, whole home power for weeks on end.

  • Graphic illustration of a secure power supply

    Secure Power Supply

    Permanently installed next to your solar inverter, secure power supply can be used to charge essential electronics during the day. However, because this solution runs on solar power and does not have a battery, it doesn’t work at night or when it’s cloudy.

  • Backup Battery

    An innovative but expensive option, back-up batteries cost up to three times the price of a similarly sized backup generator. Back-up power beyond 1-3 days requires sufficient sunlight to recharge the batteries.
