About This Service

A home battery stores electricity and gives it back when the grid goes down. The battery and its inverter mount on a wall, usually in a garage, a basement or a utility room, and charge from the grid or from solar panels if you have them. When the power fails, the system switches your chosen circuits over to the battery in a fraction of a second, fast enough that most homes never notice. It runs with no engine, no fuel and no exhaust, so it is quiet and can sit close to the house. How long it lasts depends on the battery's capacity in kilowatt-hours and on how much your home is drawing at the time.

Most home batteries hold 10 to 15 kilowatt-hours each. At a modest 5 kilowatt draw that lasts about two to three hours, which is why most homes back up the essential circuits rather than everything: the furnace blower, the fridge, the sump pump, the internet and some lights. More units extend the runtime, and a standby generator can take over when a long outage would drain the battery. We start with a load assessment, size the system from what you want to keep on, install the backup panel or transfer device and the wiring, file the Electrical Safety Authority (ESA) notification of work and arrange the inspection. If you are on a time-of-use or ultra-low overnight rate plan, the same battery can also charge overnight and cover the expensive hours of the day.

What We Do

✓

Essential-Circuit Backup

A battery and inverter that pick up your chosen circuits within a fraction of a second when the grid drops.

✓

Load Assessment and Sizing

We list what you want to keep on, measure the loads and size the battery in kilowatt-hours and kilowatts from that list.

✓

Backup Panel or Transfer Device

The circuits you back up move to a backup panel or run through a transfer device, so the battery never feeds the grid.

✓

Generator and Battery Together

A battery for the short outages and a standby generator for the long ones, wired to work as one system.

✓

Permits and ESA Inspection

The Electrical Safety Authority (ESA) notification of work is filed before we start, and the work is inspected when it is done.

✓

Time-of-Use Charging

On a time-of-use or ultra-low overnight plan, the battery can charge in the cheap hours and carry the house in the expensive ones.

What's Included

  • Load Assessment

    We list the circuits you want covered, measure their running and starting draw and note any motor loads that need extra at start-up.

  • System Sizing

    The battery's usable kilowatt-hours and its continuous and peak output are matched to that list, with room for how long you want to run.

  • Backup Panel or Transfer Device

    The backed-up circuits move to a backup panel or are fed through a transfer device that isolates them from the grid during an outage.

  • Battery and Inverter Installation

    The battery and inverter are mounted, wired to the panel and to the backup circuits, with every connection secured and labelled.

  • Generator Integration

    Where a home has a standby generator, or plans one, the battery and the generator are wired to work together.

  • ESA Notification and Inspection

    The notification of work is filed with the Electrical Safety Authority before we start, and the installation is inspected when it is complete.

  • Set-Up and Walk-Through

    The backup and charging settings are configured, and we show you how to read the state of charge and what the battery is carrying.

Signs You Need It

Short Outages Are Your Problem

If your area sees frequent brief outages rather than days-long ones, a battery covers them without an engine starting.

You Need Silence or Have No Gas

A battery runs silently and needs no fuel line, which suits a small lot, a dense street or a home without natural gas.

You Have Solar Panels

A battery stores your own solar energy for use after dark or during an outage instead of sending it all back to the grid.

Someone Relies on Medical Equipment

Power that switches over in a fraction of a second matters when a CPAP machine or an oxygen concentrator is running.

Your Sump Pump Cannot Stop

A sump pump that loses power in a storm can flood a basement in Hamilton's clay soils, and a battery keeps it running through a short outage.

You Are on a Time-of-Use Plan

A battery that charges overnight and runs the house at the peak rate shifts your usage even when the grid is up.

How It Works

1

Consultation and Load Assessment

We visit, look at your panel and list the circuits you want covered, with their running and starting loads.

2

Design and Written Quote

You get a written quote for a system sized to that list: the battery capacity and output, the backup panel or transfer device and the wiring.

3

Installation

The battery and inverter go up, the backup circuits are moved or switched, and everything is wired, secured and labelled.

4

Testing and ESA Inspection

We simulate an outage to confirm the switch-over and the loads, then the Electrical Safety Authority inspects the work.

What Affects the Price

Battery systems are quoted after a site visit and a load assessment, so the quote reflects your loads and your panel.

  • Battery Capacity

    More kilowatt-hours means longer runtime and more units, and each unit adds to the job.

  • Circuits Covered

    Backing up a handful of essential circuits costs less than covering the whole home, which needs more output and more storage.

  • Backup Panel or Transfer Device

    Moving circuits to a new backup panel is more work than switching an existing sub-panel, and the state of the panel matters.

  • Generator Integration

    Wiring a battery to work with a standby generator adds control wiring and equipment to the job.

  • Solar and Rate Plans

    Pairing with solar panels, or setting the system up for time-of-use charging, adds equipment and configuration.

  • Panel Condition

    Before the inverter and the backup circuits go in, an older panel may have to be upgraded.
