3.6kWh today, 36kWh tomorrow, at a price the big names cannot touch.
Key Takeaways
- 3600Wh of LFP storage, 3600W of output, expandable to 36kWh.
- Two units in parallel deliver 240V/7200W whole-home power.
- Sub-15ms EPS switchover and 2000W solar input.
- Around CA$2,270.68 (checked 2026-10-14).
There comes a point where a “portable power station” stops being portable and starts being a power plant. The GROWATT HELIOS 3600 lives right on that line. 3600Wh of LFP storage, 3600W of output, expansion all the way to 36kWh, and the ability to parallel two units for 240V/7200W whole-home power, all at a price the big-name flagships cannot touch. Its flagship rival is the Jackery Explorer 5000 Plus, which costs more for a fixed 5kWh.
The expansion roadmap is unmatched at this price
36kWh is Tesla-Powerwall territory: a week of home power from a system you can build one battery at a time. Start with the 3.6kWh base unit for outages and camping; add batteries as budget allows; parallel a second unit when you want 240V for air conditioning, dryers, and well pumps. No other unit near CA$2,270 offers a roadmap like that.
How fast can solar recharge the HELIOS 3600?
Faster than you would expect. The 2000W solar input recharges from the sun in under three hours of good light, and the 3600W AC-DC hybrid mode fills it in under 90 minutes from the wall. For storm country, that means you can cycle the unit daily: drain it through the night, refill it by midday.
The sub-15ms EPS switchover deserves attention too. Plugged in as an emergency power supply, it hands off to battery faster than most UPS units, keeping computers, networking gear, and medical devices running without a blink. If you are still deciding how much capacity your home needs, our power station sizing guide walks through the math.
What the price does not include
At 3.6kWh this is a heavy, vehicle-moved unit, not something you carry one-handed to a campsite. The 240V/7200W parallel capability and the full 36kWh expansion require buying additional units and batteries, so budget for the system you actually want. And while Growatt is a solar-industry heavyweight, its portable power brand recognition in North America is newer than Jackery or EcoFlow, so dealer and service networks are still growing. Buyers wanting a mid-size expandable system instead should see the EcoFlow DELTA 2 Max.

At the base 3.6kWh, it delivers up to 15 hours of daily home devices or 1 to 3 days of emergency power for refrigerators. Expanded to the maximum 36kWh, it can provide up to 7 days of home power. Expansion batteries and a second unit for 240V/7200W are purchased separately, so budget for the system you actually want.
How fast does the HELIOS 3600 recharge?
Very fast. The 2000W solar input recharges it from the sun in under three hours of good light, and the 3600W AC-DC hybrid mode fills it from the wall in under 90 minutes. For storm country, that means you can cycle the unit daily: drain it through the night, refill it by midday.
How much does the GROWATT HELIOS 3600 cost?
Around CA$2,270.68 (checked 2026-10-14). That delivers flagship-class capability, 3.6kWh, 3600W, and a 36kWh expansion roadmap, at a price the big-name flagships cannot touch. It is the value disruptor of the flagship class and the smartest money in serious home backup right now.
The Bottom Line
The HELIOS 3600 is the value disruptor of the flagship class. 3.6kWh, 3600W, sub-15ms EPS, and a 36kWh expansion roadmap at CA$2,270.68 make it the smartest money in serious home backup right now.
