Backup battery questions
Cost, runtime, brands, solar pairing and rebates.
What are the features of SolarEdge Home Battery?
The SolarEdge Home Battery offers 9.7 kWh usable capacity per battery with 5 kW continuous power output (7.5 kW peak). It features DC-coupled design for 94.5% round-trip efficiency, advanced monitoring via the mySolarEdge app, and flexible installation options (indoor/outdoor, wall/floor mount). The system is UL9540A compliant and backed by a 10-year warranty with 70% capacity retention guaranteed.
How long can backup batteries last during power outages?
Backup batteries can provide up to 45 hours of runtime when powering only essential loads like refrigerators, lights, and medical devices. For whole-home backup, runtime typically ranges from 8-24 hours depending on usage patterns. When paired with solar panels, your backup time can be extended indefinitely during daylight hours as the panels recharge the batteries.
What are the financial benefits of backup batteries?
Financial benefits include: offsetting peak electricity rates by using stored energy during expensive time-of-use periods, reducing demand charges, maximizing solar self-consumption (avoiding selling excess solar at low rates), and protection from grid price volatility. Most homeowners see 5-7% annual ROI through energy cost savings, with systems paying for themselves within 10-15 years while providing invaluable backup power security.
How do backup batteries boost energy independence?
Backup batteries provide true energy independence by storing solar energy for use anytime – day or night. Advanced features include automatic severe weather event detection that prepares your system before storms hit, intelligent energy management that optimizes charge/discharge cycles, and seamless grid integration that allows you to reduce reliance on utility power. You control your energy destiny rather than being at the mercy of grid outages and rate increases.
Why are backup batteries a solid investment
Backup batteries are a solid investment backed by robust 10-year warranties with 70% capacity retention guaranteed. They provide dual value: daily energy cost savings through time-of-use optimization and peak shaving, plus critical backup power during emergencies. Unlike generators, batteries require no maintenance, no fuel costs, operate silently, produce zero emissions, and can be used every day – not just during outages. With 6,000+ cycle lifespans (15+ years), increasing grid instability, and rising electricity costs, batteries deliver long-term value and peace of mind.
How long will backup batteries power my home?
Depends on battery size and usage. A typical whole-home system provides 1-3 days of backup for essential loads, longer when paired with solar. A single 9.7 kWh battery can power essential circuits for up to 45 hours.
Can I use batteries without solar panels?
Yes! Batteries can charge from the grid during off-peak hours and provide backup power during outages or peak rate periods. However, pairing with solar maximizes your savings and energy independence.
What's the difference from a generator?
Batteries are silent, emissions-free, require no fuel, activate instantly (within milliseconds), and can be used daily for energy cost savings – not just during outages. Generators are noisy, require regular maintenance, consume fuel, and are typically only used during emergencies.
How long do backup batteries last?
Most home battery systems last 10-15 years with minimal degradation. SolarEdge batteries come with 10-year warranties guaranteeing at least 70% capacity retention and are rated for 6,000+ charge cycles.
Can I expand my battery system later?
Absolutely! Battery systems are modular and scalable. Start with one 9.7 kWh battery and add more as your energy needs grow. This future-ready design protects your investment and adapts to changing household requirements.
How long do solar batteries last?
Modern LFP (lithium iron phosphate) solar batteries last 15+ years and are rated for 6,000+ charge cycles. Most carry 10-year warranties guaranteeing 70% capacity retention. NMC batteries have shorter lifespans (10-12 years, 3,000-5,000 cycles). Lead-acid batteries only last 3-5 years and are not recommended for grid-tied homes.
How many solar batteries do I need?
For essential backup (fridge, lights, internet, sump pump), one battery with 10-13.5 kWh capacity is enough for most homes. For whole-home backup including air conditioning, heat pumps, and EV chargers, plan for 20-27 kWh (two batteries). The key factor is power output (kW), not just capacity.
Are solar batteries worth it in Canada?
Yes, for most Canadian homeowners. In provinces with time-of-use pricing (Ontario, parts of BC), batteries save money daily by shifting consumption from peak to off-peak rates. Add backup power protection and rebates up to $5,000, and batteries deliver both daily savings and insurance against outages. Best ROI in Ontario, BC, NWT, and Nova Scotia.
Buyer's guide
What Solar Batteries Do and Why Canadian Homeowners Need Them
Solar batteries store the excess energy your
solar panels generate during the day so you
can use it when the sun isn’t shining. Without a battery, surplus solar energy goes to
the grid through net metering. With a battery, you keep
that energy for yourself, using it at night, during peak rate hours, or when the power
goes out.
For Canadian homeowners, three factors make batteries especially valuable. First,
grid reliability: ice storms, wildfire smoke events, and aging
infrastructure cause outages across every province. A battery keeps your home running
when the grid fails. Second, time-of-use optimization: in Ontario and
parts of BC, electricity costs 2x more during peak hours. Batteries charge at off-peak
rates and discharge during expensive periods, saving money every day. Third,
net metering gaps: provinces like Manitoba (4.39¢/kWh export)
and Saskatchewan (7.5¢/kWh) pay far less for exported energy than what you pay to
buy it back, making self-consumption via battery storage more profitable than
exporting.
Solar Battery Cost in Canada and Available Rebates
Solar battery prices in Canada range from $8,000 for a basic essential-load system to
$18,000+ for a high-capacity whole-home solution like the Tesla Powerwall 3. Combined
solar + battery packages start around $35,000 before incentives. See our
pricing page for system-specific costs.
Provincial rebates can offset a significant portion. Ontario’s HRSP offers
$5,000 for battery storage (on top of $5,000 for solar, capped at
$12,000 total). BC Hydro provides $5,000 for batteries, though
accepting the rebate changes your export rate. NWT’s AEA program offers up to
$20,000 for diesel communities.

Types of Solar Batteries
Lithium Iron Phosphate (LFP)
Used in Tesla Powerwall 3, Enphase IQ, and most modern home batteries. Safest lithium chemistry with no thermal runaway risk. 6,000+ cycle lifespan (15+ years). Lower energy density but longer life and better safety than NMC.
Recommended for Canadian homes
Nickel Manganese Cobalt (NMC)
Used in some SolarEdge batteries and older designs. Higher energy density means a smaller unit for the same capacity. 3,000-5,000 cycle lifespan. Slightly higher risk profile than LFP, though still safe with proper thermal management.
Good option, shorter lifespan
Lead-Acid
Older technology, still used in off-grid cabins. Much cheaper upfront but only 50% depth of discharge, 500-1,000 cycle lifespan (3-5 years), and requires ventilation. Not recommended for grid-tied residential solar systems.
Off-grid only

Solar Battery Questions
How long do solar batteries last?+
Modern LFP (lithium iron phosphate) solar batteries last 15+ years and are rated for 6,000+ charge cycles. Most carry 10-year warranties guaranteeing 70% capacity retention. In practice, a battery installed today will still be functional well into the late 2030s. NMC batteries have shorter lifespans (10-12 years, 3,000-5,000 cycles) but are still a solid investment. Lead-acid batteries only last 3-5 years and are not recommended for grid-tied homes.
How many solar batteries do I need?+
For essential backup (fridge, lights, internet, sump pump), one battery with 10-13.5 kWh capacity is enough for most homes. For whole-home backup including air conditioning, heat pumps, and EV chargers, plan for 20-27 kWh (two batteries). The key factor is power output (kW), not just capacity: running an AC unit and heat pump simultaneously requires 8-10 kW, which a single 5 kW battery can't deliver. We size every system based on your actual energy usage data and backup priorities.
Are solar batteries worth it in Canada?+
Yes, for most Canadian homeowners. In provinces with time-of-use pricing (Ontario, parts of BC), batteries save money every day by shifting consumption from peak to off-peak rates. In provinces with low net metering export rates (Manitoba 4.39¢, Saskatchewan 7.5¢), keeping solar energy for self-consumption via battery is significantly more valuable than exporting it. Add in backup power protection (Canada averages 7+ hours of outages per year, much more in rural areas) and rebates up to $5,000, and batteries deliver both daily savings and insurance against outages. The best ROI is in Ontario, BC, NWT, and Nova Scotia.
