Growatt HELIOS 3600 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.

Surge output stays unknown because the checked official table publishes rated AC output per outlet group without a peak rating. The 3600W figure is the published total across the four 20A outlets; the same table lists a separate 2200W 240V outlet. DC output uses the listed 13.2V/30A Anderson port. Expansion batteries are sold separately and are not modeled here.

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.

Warnings

  • This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

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.
  • Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
  • USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
  • Tracked solar input is 2,000 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: surge 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.
