EG4 Battery Installer in Ontario: What a Proper EG4 Installation Includes

What Does an EG4 Installer Actually Do?

An EG4 installer does a lot more than hang an inverter on the wall and stack batteries beside it. The work starts well before any equipment shows up on site.

A proper installation begins with a load review. We look at your hydro bills or your generator use, find out which circuits need backup, and size the inverter and battery bank to what you actually use. An undersized system lets you down in a long outage. An oversized one costs more than it needs to.

From there we design the system, choose the right EG4 inverter for the job, source the equipment, handle permits and book the ESA inspection that every Ontario electrical installation requires. All panel work is done by our own licensed master electrician. Nothing connects to your home's electrical system without proper sign-off.

Which EG4 System Fits Your Property?

EG4 makes several platforms, and choosing the right one is the first thing a good installer gets right.

• Whole-home backup on the grid: an EG4 hybrid inverter (18kPV or FlexBOSS18) with the EG4 GridBOSS. The GridBOSS switches your whole home to battery power during an outage and manages a backup generator and large loads.
• Off-grid cottages, cabins and shops: the EG4 12000XP or 6000XP for indoor installs, or the outdoor-rated FlexBOSS18 with the All-Weather battery when there is no good indoor spot.
• Batteries: every system runs on EG4 14.3 kWh LiFePO4 batteries with a 10-year warranty. Add more batteries as your needs grow.

What Does a Proper EG4 Installation Include?

Load review and design: what needs to stay on during an outage, how long it needs to run, and what the surge loads are, such as a well pump, sump pump or air conditioner.

Battery placement to code: Ontario has specific rules for where home batteries can go. Outside on an exterior wall or in a garage is the simplest option, and both EG4 All-Weather batteries and our outdoor installs are built for it. An indoor install needs a dedicated room with a fire-rated, self-closing door, drywall and a smoke alarm, and it can never open into a bedroom.

• Neat, protected wiring: every EG4 install we do runs through a conduit box between the inverter and the batteries, with clean, enclosed wire runs.
• Permits and ESA inspection: we file the ESA permit and, for solar, the utility application. The system is not energized until it passes inspection.
• Commissioning and handover: we set up the EG4 monitoring app, test the system under load, and walk you through what happens during an outage.

Licensed Installation vs DIY

EG4 equipment is popular with do-it-yourselfers, and for a small portable setup that can work. For a system tied into your home's electrical panel, it is a different story.

• Permits and inspection: in Ontario, a battery system wired into your panel needs an ESA permit and inspection, and anyone you hire to do the work must be a Licensed Electrical Contractor. An unpermitted install is non-compliant, no matter how tidy it looks.
• Insurance: an uninspected battery system can create problems with your home insurance after a claim.
• Rebates: the Ontario Home Renovation Savings rebate for solar and batteries is only available when a contractor installs the system with pre-approval.
• Safety: large battery banks store a lot of energy. Correct breaker sizing, wire sizing and battery placement are what keep that energy safe.

Generators and EG4 Systems

If you want generator backup for long outages, use an inverter-type generator. Inverter generators produce the clean, stable power that battery inverters need. The EG4 12000XP can start and stop a 2-wire start generator automatically based on battery level, and on whole-home systems the GridBOSS manages the generator. Tell us your generator make and model and we will confirm it before we promise anything.
