Battery Storage

Store your solar. Power through outages.

Charge Cheap, Use When It's Expensive

On Ontario's Ultra-Low Overnight plan, a battery fills up overnight at the lowest rate and runs your home during the weekday 4–9 p.m. peak, when grid power costs about ten times more. With solar, it also stores your surplus for the evening.

Rates are set by the Ontario Energy Board and change each November. We use current rates in your proposal.

Backup Power

Keep the fridge, furnace fan, sump pump and Wi-Fi running when the grid goes down.

Rebate Eligible

Batteries sized for load displacement can qualify for the Home Renovation Savings Program.

Add Anytime

Pair with new solar or add a battery to the system you already have.
