An example to understand your battery
See what happens when you switch on
your appliances.
An illustrative simulator to understand charging, consumption and remaining energy. Adjust the inputs and watch the balance; this is not telemetry from a real power station.
01What is switched on?
Power use of the example devices ↓
- Airfryer · AC · 1500 W
- Espresso machine · AC · 1400 W
- 12 V fridge · DC · 45 W
- USB-C laptop · DC · 65 W
- Starlink dish · AC · 50 W
- Camper LED lights · DC · 15 W
Power losses when using a socket ↓
Inverter assumptions: 15 W idle draw and 85% conversion efficiency. Daily consumption depends on hours of use.

Is it cold?
In this example, you are using more energy than comes in.
Estimated time until the battery runs out: ~32.9 min estimated
Illustrative example: a generic battery with 1024 Wh at 80%. It does not represent a real model or guarantee runtime, charging or compatibility.

How this example is calculated ↓
Planning assumptions shared with the calculator: solar 75%, AC 85%, DC 95%, inverter idle draw 15 W and car input 100 W. These are not manufacturer measurements. This simulator estimates the instantaneous balance with constant loads and depletion to 0%; the calculator accounts for hours of use and keeps a 10% battery reserve.
Understanding the balance does not mean choosing a power station.
This is an example, not a real battery. To choose one, check your devices, cables and operating conditions.
What this example does not check ↓
Capacity is assumed and does not represent any model. Continuous output, start-up loads, connectors, voltage and port limits are not validated. To find candidates, enter appliances, hours and days in the calculator and review their documented evidence.
Watts describe power at this instant. A peak sun hour represents an hour at reference irradiance, not any clock hour. Replacing daily consumption and fully charging a battery are different goals.
