PumpGuard 24h · Well & Sump Pump Backup
12-hour overnight backup guarantee — covering the dark hours, unattended, when it matters most. Seamless transfer in ≤20ms the instant power fails. You sleep; the pump stands watch.

Backup runtime guaranteed under design conditions — get through the storm night
Transfer time on outage — the pump never notices the power failed
Usable storage (approx.); 6kW peak covers starting surges
Silently on standby, takes over the instant power fails, recharges itself when power returns. Fully automatic — you never touch it.
While grid power is normal the system stands by, battery kept full, status anytime in the app.
The moment grid power drops, the inverter takes over — the pump never stops, you won't even notice.
Battery drives the pump all night; one-tap self-test before storm season.
Back on grid power, fully recharged in about 3.5 hours — ready for the next storm.

120V single-phase in and out, Square D QO breakers, cUL/CSA/ETL-listed components, installed by a licensed electrician with permit. Standard install goes in the basement/utility room indoors — temperatures there are kind to LiFePO4, no heating needed.
The difference isn't the battery, it's the brain: dual-pump wear levelling, water metering, fault diagnostics, pre-storm self-test, remote monitoring in the phone app.
Usable energy approx. 4.6kWh (after inverter losses). The 12-hour promise is calculated at 1/2 HP design conditions.
| Pump | Running watts | Continuous pumping | Intermittent storm |
|---|---|---|---|
| 1/4 HP | ~190W | ~24 hours | 40+ hours |
| 1/3 HP | ~250W | ~18 hours | 30+ hours |
| 1/2 HP (design case) | ~375W | ~12 hours | 20+ hours |
| 3/4 HP | ~560W | ~8 hours | 14+ hours |
Intermittent-storm figures assume ~55% duty cycle; 6kW peak covers all pump starting surges (~800–2200W). Drainage figures are typical (1/2 HP ≈ 3,500–4,500 GPH @10 ft head, ≈48,000 gallons over 12 hours) — go by your pump’s nameplate.
Not upgrades of each other — they're for different homes. Count your pumps and you'll know.
One 120V pump circuit, one main pump (up to 3/4 HP). 12-hour runtime under design conditions.
Same battery and inverter as Standard, but output runs through two independent 120V branches, each with its own breaker. Each pump on its own circuit (one tripping can’t take down the other), wear levelling, mutual backup.
Two battery packs, 2–3 pump circuits, 24+ hour runtime. Note: same 3kW inverter — runs longer, not stronger.
Price includes professional installation by a licensed electrician, with permit.
Drainage figures and install conditions confirmed by site survey.
November 2026, a detached home in Metro Vancouver. The night the whole street lost power:
Driving rain, sump level rising, pump cycling. All normal.
The whole street goes dark. PumpGuard takes over in 20ms — you’re asleep; the pump stands watch.
Rain at its heaviest, pump working hard, battery comfortably past halfway. The basement is dry.
Rain easing, pump back to intermittent, plenty of charge left.
Grid power returns, battery starts recharging. You wake up — nothing happened. That’s the whole point.
A generator is today’s workaround — but it’s yesterday’s answer.
| PumpGuard | Gas generator | |
|---|---|---|
| Power-loss response | Automatic, ≤20ms | Get up at 3am to pull-start it |
| Noise | Silent | 70–90 dB — the neighbours will notice |
| Runtime | 12+ hours, guaranteed by design | 5–8 hours, depends on the tank |
| Fumes / fuel storage | None, installs indoors | Outdoors only, gasoline goes stale |
| Maintenance | None, automatic self-test in the app | Oil changes, test runs, servicing |
Most 120V, 1/2–3/4 HP sump / sewage pumps work. Send us a photo of the nameplate and we’ll confirm wattage, voltage and circuits.
Standard install goes in the basement / utility room indoors — temperatures there are kind to LiFePO4, no heating needed. Outdoor installs quoted separately.
A regular UPS is designed for computer loads — it can’t handle a pump’s starting surge and won’t last 12 hours. PumpGuard is designed around pump duty from the ground up: 6kW peak, 4.6kWh usable, 12-hour guarantee.
No. One-tap self-test before storm season; the system watches itself the rest of the time. If anything looks off, you get a push notification.
Send us a photo of your pump’s nameplate — we’ll verify the configuration and the quote. When others lose power, you don’t.
