Questions to ask your contractor

  1. Which loads does this design carry, and what runtime does it assume?
  2. Is a critical load panel included, and which circuits go on it? What a battery system costs
  3. Where does the enclosure mount, and what clearances does it need?
  4. Can this system be paired with solar or a generator later?
  5. What does the warranty cover on the battery, and is capacity loss included?

How do I choose a home battery backup installer in the GTA?

Home Generator Index lists 9 home battery backup installers at an average 4.26★ Google rating, the middle company sitting on 13 reviews. Take three from the shortlist above and get the scope written down. What to check before anyone opens a panel, including the ECRA/ESA licence number and who owns the gas half of the job, is set out on the methodology page.

Is there a season for home battery backup in Toronto?

There is no booking season to catch, since availability holds year-round. What changes is the aftermath of an outage, when a whole region decides on backup power in the same week and the wait stretches out well after the lights are back. The quiet stretches are when a company will spend an hour on your load list. Ask each one how far out its schedule currently sits, and whether the site visit is charged.

Will a contractor's cheque move it up this page?

No, and no business has an account here to pay through. The order comes from the Home Generator Index Score out of 100, built from what customers said, what the company states on its own website and how much is on its record. With 44% of the rated home battery backup installers at 4.8★ or better, the positions are decided in narrow margins, so read past the first row. The methodology page sets out every input.

Battery backup or a fuel generator for a home in the Greater Toronto Area?

They fail at different things. A battery is silent, has no exhaust, needs no gas line and no TSSA gas fitter, and can go in places a generator legally cannot. Its limit is runtime: capacity divided by load, and no refuelling. A multi day winter outage is the case where a battery alone struggles unless it is paired with solar or a generator. Ask an installer which loads the design carries and what runtime it assumes, then check that against how you actually lost power last time.

Whole home backup or critical loads only in the Greater Toronto Area?

Critical loads means the short list that keeps a house safe and habitable: the furnace and its blower, the sump pump, the fridge and freezer, a well pump if the property has one, and some lighting and outlets. Whole home means everything, including air conditioning and an electric range, and it costs more at every stage: bigger unit, bigger fuel demand, bigger switchgear. Load management sits between the two, shedding the heavy loads so a smaller unit can carry the house. Ask which of the three a quote is priced on.
