EcoFlow DELTA Pro Ultra Installed in Ontario: What the Job Looks Like

What the DELTA Pro Ultra Is Built For

The EcoFlow DELTA Pro Ultra is a home battery backup. When the power goes out, it keeps the circuits that matter running: the fridge and freezer, the furnace fan, the sump pump, the well pump, lights, internet and a few outlets. It is quiet, it runs indoors, and there is no fuel to store.

It is built for battery backup of your critical loads. It is not a grid-tied solar system, and it does not send power back to the grid. If you want solar that offsets your hydro bill, or you want the Home Renovation Savings rebate, an EG4 solar and battery system is usually the better fit. We cover that in our guide to whole-home battery backup.

Step 1: Pick the Circuits

Every install starts with a short list of what you want running in an outage. We look at your panel, ask how you live, and pick the circuits that go on backup. A typical list is the fridge, a freezer, the furnace fan, the sump pump, the well pump if you have one, the kitchen and living room outlets, internet and some lights.

That list sets the battery size. One DELTA Pro Ultra battery holds 6 kWh, and you can stack more batteries when you need a longer run time. We size it so the essentials last through the kind of outage your area actually gets, not a number on a box.

Step 2: The Smart Home Panel 2

The DELTA Pro Ultra connects to your home through the EcoFlow Smart Home Panel 2. Our licensed electrician installs it beside your main electrical panel and moves your backup circuits onto it. When the grid drops, the panel switches those circuits to the battery on its own. When the grid comes back, it switches back and recharges.

You can see every circuit in the EcoFlow app, turn circuits on or off, and watch how much battery is left. That is the part customers like most during a long outage.

Step 3: Permit, Wiring and Inspection

Wiring a backup system into your home is electrical work, so it needs a licensed electrician and an ESA permit. We file the permit, do the wiring with our own licensed master electrician, and book the ESA inspection. Nothing is left as a cord and a plug.

Most DELTA Pro Ultra installs are done in a single day. We set up the battery, wire in the Smart Home Panel 2, test a full switch to battery power with you there, and set up the app on your phone.

Adding Solar or a Generator

The DELTA Pro Ultra can take solar panels, which is a good way to stretch a long outage or run a cottage that sees a lot of sun. A generator can also top the battery up during long grey stretches. The battery stays the main source; the generator is only the backup to it.

Warranty and Support

TRU Off Grid is an authorized EcoFlow dealer. Units bought through us carry the EcoFlow warranty with support from our team in Milton, and because we work closely with EcoFlow Canada, warranty replacements usually move quickly. If something comes up, you call us, not a help desk overseas.

Is It the Right Fit for You?

The DELTA Pro Ultra is a great choice when you want reliable backup for your essentials, no fuel, no noise and a clean install. If you want to cut your hydro bill with solar, back up the whole house, or qualify for the rebate, ask us about EG4 instead.
