Runtime simulator

How long will the power station last?

Pick your devices, station and location. Wattpass calculates runtime hour by hour, including inverter losses, the station's idle draw, startup surges and solar yield where you are.

  • Idle draw of 18 W is an estimate. Adjustable under "Fine-tuning".
  • Continuous and surge ratings are sufficient for these devices.

01 Devices

Typical values; check your device's nameplate.

  • Refrigeratorcompressor, runs about 28% of the time (≈ 370 kWh/yr) · startup 3× (450 W)
  • Wi-Fi routervia DC/USB
  • LED lampvia DC/USB

Per day: 1,224 Wh at the devices, 1,801 Wh from the battery (with losses and idle draw).

02 Station

Watts (W) = what can run at the same time. Watt-hours (Wh) = how long it lasts.

Fine-tuning Typical, start 8 am

Conservative assumes an aged battery, lower efficiency and less sun.

Starting charge

Default 18 W is an estimate without a manufacturer figure.

How it's calculated →

How the simulator calculates

  • Not all rated capacity is usable: depth of discharge (LFP 95%, NMC 85%), battery health and cold are deducted.
  • While any AC device is switched on, the inverter runs and draws its idle power, even when the device pauses. A load-dependent conversion loss comes on top.
  • Fridges cycle on and off; motors and compressors need a multiple of their running watts at startup. That is checked against the station's surge rating.
  • Solar yield comes from the month's peak sun hours at your location and is capped at the station's solar input.
