See every priceRetrofit · solar you already have
Already have solar? Here is what a battery changes.
Solar on its own goes dark when the grid does. A battery changes that, and it works with the panels you already have.
Step 1
The grid goes down
Your solar inverter shuts itself off. It is built to, so it never feeds a line a crew is working on. That is why solar alone keeps nothing on.
Step 2
The battery cuts you off the grid
It opens a switch on its own and runs a small grid inside your house.
Step 3
Your solar comes back on
Your inverter sees that small grid and starts producing again. It runs the house and tops up the battery while the sun is up.
There is a limit on how much solar one battery can take in an outage. I check your inverter label and size the battery to your array, or tell you straight which part of it sits out.
How big is your solar system?
The kW on your inverter label or your install papers, 3 to 20 kW.
Don’t know your kW? Use one month from your app.
Pick the month and type what your app says your solar made.
Monthly yield per kW from Natural Resources Canada for Edmonton, south facing at latitude tilt. Same table as is solar worth it in Alberta.
Enphase also makes its own battery, and it may fit your system even better. I compare both for you.
A battery can still work with APsystems. A generator is where they draw the line: APsystems says its warranty does not cover microinverters used with a generator. Tell me up front if you want one later.
Same check either way. I read your inverter label and confirm the limit for it.
Send me a photo of the inverter label and I will tell you. Send the photo
Tesla Powerwall 3
Each unit takes up to 7.68 kW of your solar

Or fewer units, with the solar past their limit on its own cutoff that stays off in an outage.
Worked example from each maker's published limit. Tesla allows 7.68 kW AC of existing solar per Powerwall 3 in the backup circuit, counting the smaller of your inverter's AC rating and your panel size, or 10 kW with an Expansion unit.
FranklinWH's manual caps solar at the batteries' total charging power, 8 kW per aPower 2. Final design follows your inverter label and a site visit.

Open the battery comparisonWhere the power actually goes
How battery storage works in a real Alberta home
Same system, three different days. Tap one.
Sunny day: the panels run the house and top up the bank
Your array covers the daytime load first, then charges the battery, then sends whatever is left to the grid as an export credit under microgeneration. Nothing is wasted and the bank is full before evening.
Evening: the house runs off the battery instead of the meter
The sun is down and the load is at its peak. The battery discharges into the house rather than you buying that power back from the grid. This is the part that shrinks the bill, not just the outage risk.
Grid outage: the house islands off the grid on its own
The transfer switch disconnects from the dead utility feed automatically and the battery carries your backed up circuits. If you have solar, it keeps charging in daylight while the grid is still out. You are not out dragging a generator into the snow at 2am.

Runtime · battery alone, no sun
How long it runs, at three loads
Hours equal usable kWh divided by the average load, rounded down. No sun and no generator, so this is the worst case.
All three loads in one table

- Tesla Powerwall 3. Tesla's own table says it can't charge from a generator wired ahead of it and can't start one.

Size my batteryOptions, With The Reason For Each
Three ways to size a battery
Battery quotes tend to arrive as one size and one price. What it should be depends entirely on how much of the house you want running.
Option 1
Essentials only
lightest cost
Best when you want the furnace, the fridge and a few plugs to ride through and you can live without the rest.
A smaller battery carries a short list for a long time. It is the cheapest way to stop losing a freezer full of food and to keep the heat on.
The circuits you leave off stay off. We pick that list together before anything is ordered.
Option 2
Whole home backup
heaviest cost
Best when you want nothing in the house to change during an outage.
Nobody has to ration anything or remember which plugs still work. The house behaves normally and you find out about the outage from a neighbour.
Carrying everything means carrying the big loads too, so this needs more battery and often a service that can support it.
Option 3
Battery paired with solar
heaviest cost
Best when you want the bill down and the lights on, and you are doing this once.
Solar handles the bill through net metering. The battery handles the outage. They are two separate jobs and pairing them means one permit, one crew and one trip rather than two of everything.
Doing both at once is more money in one year. It is less money than doing them two years apart.
One thing worth knowing before you compare spec sheets. The capacity number on a datasheet is a room temperature number, and an unheated garage in an Edmonton January is not room temperature. Ask any installer where they plan to mount it, and what they expect out of it at that temperature.
Price is scope, not markup
What moves the price
Five things decide your number. Tap any one for the short version.
Battery capacity
Biggest single lever
More usable kWh means the bank lasts longer between charges, and it is the largest line on the quote.
Overnight essentials
5 kWh
a different price class
A 5 kWh bank that carries the fridge and furnace fan overnight.
The whole house
13.5 kWh
a different price class
A 13.5 kWh unit that carries the whole house.
The 5 kWh bank is a different price class than the 13.5 kWh unit.
Stacking more modules later is cheaper than buying the biggest bank on day one, because the panel work we do for the first battery is the same work a full bank needs.
Essential load scope
You control this one
- Backing up a few essentials costs a lot less than running the whole house through an outage.
- Deciding what actually has to stay on, fridge, furnace fan, lights, plugs, well pump, sets both the battery size and the inverter size.
- A bigger inverter to carry heavier loads costs more than more kWh does.
Panel and transfer work
Depends on your house
- A battery ties straight into your main panel. Splitting your circuits so the right ones land on the backed up side takes a subpanel and a transfer switch, and the type of switch depends on the loads.
- If your existing panel is full or undersized, that work shows up here. Permit and inspection are in every price we quote, never an extra.
Solar integration
Changes the payback, not just the price
- Pairing the battery with solar means it refills from the sun instead of only from the grid, so an outage becomes days rather than hours.
- If you already have an array, the work is tying into the existing inverter. If you do not, a hybrid inverter sized for both is usually cheaper than doing the two jobs separately.
- Charging from the grid still costs you. Charging from the sun does not.
Install complexity
Site specific
- Where the battery mounts, how far it sits from the panel, whether the run is through a finished basement or an open garage wall, and whether the wall needs backing all move the labour.
- We look at this on site before we put a number on paper, which is why the quote you get is for your house and not a template.
You decide how far to take it, and the price follows the system you actually choose. We can post these prices because the electrician sets them, not a salesperson padding a commission.
Already have solar? Eight things move a retrofit price.
No price ranges here yet. I price a retrofit off the walkdown.
How many batteries
One or two. The hours you want and the size of your array decide it.
Gateway or islanding hardware
The switch that cuts your house off the grid in an outage. Every backup system needs one.
Load shedding module
Drops two big 240 V loads in an outage. Optional, and most useful on a whole home setup.
Generator module
Lets a generator refill the battery. Only some systems take one.
Battery spot and heat
A heated garage is simple. A cold spot can mean a heater or a different wall.
Panel condition
An old or full panel can need work before a battery goes on it.
Distance from the panel
The farther the battery sits from the panel, the more wire and labour.
Permit and utility notice
Electrical permit, inspection, and the micro generation paperwork with your wires company.
Supply Chain Your battery is already in Alberta Where the parts ship from, today
Before you chase the lowest number
A cheap battery quote looks great until the power is out and it does not carry your house.
A battery is only as good as the install behind it. The low quotes shave one of these three corners, and you do not find out which one until the grid drops and you are counting on it.

Questions Common battery storage questions Tap any question to expand
Common questions about home battery storage
Size it by the hours you want, not the whole house. Hours on battery equal usable kWh divided by your average load. At 800 W, a heavy winter load, one Powerwall 3 at 13.5 kWh runs about 16 hours and two aPower 2 at 30 kWh about 37. The runtime table on this page shows four sizes at three loads.
Yes. In an outage the battery cuts your house off the grid and your solar starts producing again on the small grid it runs. Tesla publishes 7.68 kW AC of existing solar per Powerwall 3. FranklinWH caps solar at the batteries' charging power, 8 kW per aPower 2, so two have room for 16 kW. Your inverter label tells me how much of the array stays live.
Not on its own. Grid tied solar shuts itself off when the grid drops, so it never feeds a line a crew is working on. With a battery that cuts the house off the grid, your solar comes back on, runs the house and refills the battery while the sun is up.
You pick. An essentials panel carries the circuits you choose, like the furnace, fridge, freezer, sump, internet, lights and kitchen plugs. A whole home setup keeps everything live, and a load shedding module can drop two big 240 V loads so they can't drain the battery overnight.
With some batteries, yes. FranklinWH takes one through its Generator Module, EP Cube is listed by the maker as generator compatible, and Enphase needs the IQ System Controller 3G. Tesla's own table says Powerwall 3 can't charge from a generator wired ahead of it, so I check this before you pick a battery.
It comes down to hours and your array. At an 800 W heavy winter load, 13.5 kWh runs about 16 hours and 30 kWh about 37. A big array matters too. One aPower 2 has room for 8 kW of solar and two have room for 16 kW. Solar past that goes on its own cutoff and stays off in an outage.
A garage, an outside wall or a dedicated room, and the code lists the spots. Cold is the other limit. FranklinWH rates the aPower 2 to operate from −20 °C to 50 °C, so I check how cold your spot gets before I quote it.
Depends on what you’re running. Powerwall 3 = 13.5 kWh. Hours on battery = kWh divided by your average draw in kW. Tap your loads in the picker on this page, or use the battery calculator for your real number.
Yes. A battery can go in on its own and charge from the grid, then carry the house through an outage. Be clear on what it does though. Alberta has no residential off peak rate to buy low and sell high against, so on its own a battery is backup power, not a way to cut the bill. Pairing it with solar is what gives it something cheap to store.
Yes, if part of a solar system. Federal Clean Tech Investment Tax Credit: 30% refundable (eligible businesses). Residential CEIP property tax financing covers a battery only when it goes in with a new CEIP financed solar system. Adding a battery to solar you already have does not qualify. Call us to confirm what applies.
