What size backup solution do I need?

The answer to that question depends on a number of factors, including the type of business you have and how long you need your backup power solution to last.

Energy usage is a key consideration, so we distinguish between essential load items (lights, security systems, TVs, internet routers, etc.) and heavy load items (stoves, air conditioners).

We determine the peak power requirement by adding up all the essential load items you need to operate during a power outage.


How does it work

The batteries are always ready for an outage. When there’s power available, they’re charged up and after a loss of service the inverter automatically switches over to supply your house or business with energy stored. Once back online, the process starts all over again.
