Growatt INFINITY 1500 Runtime Calculator
Quick answer: the Growatt INFINITY 1500 stores 1,512 Wh and delivers up to 1,800 W of continuous AC power. Under this site's planning assumptions (85% inverter efficiency, 10% reserve), a steady 100 W AC load runs for roughly 11.6 hours. Last source check: 2026-08-07. This is an estimate, not a guarantee.

Catalog notes (original English)
AC values use the official default 1800W / 3600W surge mode; the same table also lists a selectable maximum 2000W / 4000W surge mode. DC output uses the listed regulated 13.6V/10A cigarette socket. Cell chemistry is not published on the checked page, so it stays unknown; the table lists >800 cycles. The unit was listed as sold out at verification.
Measurement Records
Third-party results apply to the listed model, output path and test load. The delta is against a fixed no-reserve planning formula, not an error score or a prediction at other loads. Missing test conditions remain unknown.

Runtime estimate
Formula starting points use each scenario’s default watts, duty cycle and output path, with 10% reserve or 15% for CPAP. Linked detail pages use the same inputs. Hours apply only if the device can run and start; they are not measured runtimes.

This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.

Conservative12h 4m
Estimated19h 17m
Optimistic23h 56m
These are calculated sensitivity cases, not a statistical confidence interval. Conservative uses lower efficiency and battery health, more reserve/temperature loss and higher load; optimistic changes these assumptions in the opposite direction.

Planning notes
- Capacity class: 1,512 Wh. Size the battery for your measured average load and required hours, including reserve.
- Tracked output: 1,800 W. Compare both running demand and startup demand before using any runtime estimate.
- Solar input limit: 800 W. Actual refill depends on panel voltage/current compatibility, sunlight, angle and charging losses.
Known data gaps
- Unverified or missing specifications remain visible. The confidence label describes the station record, not a tested runtime or approval for emergency use.
- Weight: 16.5 kg. Check the complete carrying setup, cables and battery extensions before choosing this model for travel.
- unknown: Battery chemistry
Models: Growatt
Compare nearby capacity records from the same brand, then check output, weight and missing fields. A larger battery does not establish device compatibility.
