ZESE ZS28 Runtime Calculator
Use this source-linked record to estimate runtime from tracked capacity, output, charging, and weight fields. Unknown specs stay unknown until an official or manufacturer-grade source confirms them.
Quick answer: the ZESE ZS28 stores 4,121.8 Wh. Its continuous AC rating is not confirmed by a usable source, so this record keeps the field unknown rather than guessing — check the sources below before planning AC loads. Last source check: 2026-08-27. This is an estimate, not a guarantee.

ZESE's own page disagrees with itself on the inverter: the page title says 3600W while the heading and body copy say 3200W, so AC output stays unknown rather than being resolved by guesswork. At 63kg the ZS28 is an all-in-one home unit rather than a carryable station; plan it as fixed backup.
Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Conservative assumes harder conditions; optimistic assumes favorable conditions.
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.
- The selected station output rating is unknown, so running-load compatibility is not verified.

Warnings
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.
- The selected station output rating is unknown, so running-load compatibility is not verified.

Good fit when
- Capacity is in a larger outage/RV class, so the useful question is usually output limits, recharge speed, and weight rather than watt-hours alone.
- AC output is unknown in the current source record, so do not assume it can run AC appliances.
- Tracked solar input is 1,700 W before panel, weather, angle, and controller losses.
Watch out for
- Surge output is unknown, so do not assume compressor, pump, or power-tool startup will work.
- Still unknown in the source-backed record: ac output, surge output, dc output, usb-c output.
- Tracked weight is in a heavier class; plan where it will live before treating it as a grab-and-go station.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
