Home Backup Power Stations
Keep a refrigerator, well pump and sump pump running through any outage: the 3.6–5.4kWh LFP flagships run 7,200W when paralleled, charge an EV in an emergency, and hold 85% output at -10°C.
Will It Run My…?
| Appliance | Typical draw | Runtime on 3.7kWh (est.) |
|---|---|---|
| Refrigerator | 100–800W cycling | 1–2+ days |
| Well pump | 750–1,500W (start surge) | Hours per cycle day — check LRA |
| Sump pump | 500–1,000W intermittent | Multi-day with solar top-up |
| CPAP | 30–60W | Many nights |
| TV + router + lights | 150–250W | 15–24h |
Runtimes are engineering estimates by load — the sizing calculator and per-model inverter specs are in the quotation pack.
Parallel & Emergency Features
- Two flagships in parallel = 7,200W output for whole-home essentials.
- Emergency EV charging output (120V/30A) on the Plus variant — miles-per-hour class, get-home power.
- -10°C operation with 85% output retention on cold-weather models.
- Expansion batteries add capacity without replacing the unit; solar input to 2,400W on flagships.
FAQ
Will it run a refrigerator? How long?
A typical fridge cycles well within 3.7kWh — estimate 1–2+ days per full charge, load-dependent.
Can it start a well pump?
Yes — 3,600W+ inverters have surge headroom for pump start loads; check your pump’s LRA before ordering.
What happens during a multi-day outage?
Add expansion batteries or solar input to extend runtime indefinitely.
Can it charge an EV?
The Plus variant provides 120V/30A emergency EV charging — level 1, miles-per-hour class.
