Solar Generator & Portable Power Station Calculator
Find the battery capacity, output power and solar charging size that fit the appliances you want to run.
What do you want to power?
Add the appliances you expect to run. The calculator uses their wattage and hours of use to estimate the power station size.
Used only for the solar recharge recommendation.
This estimates how much of the battery capacity may be available to your appliances after normal battery and conversion losses. It is a planning estimate, not a product rating.
How long will a power station run my appliances?
Enter the station’s battery capacity in Wh.
Enter the manufacturer’s continuous AC output rating in watts.
Use the exact product specification when available. Actual runtime also changes with load and operating conditions.
How much solar power do I need to recharge it?
Battery capacity in Wh.
Use the manufacturer’s maximum solar charging input in watts.
Total panel wattage you plan to connect.
Use a realistic local planning value.
Allows for normal solar-system losses.
Your Result
Important: This is a planning estimate. Always compare the result with the exact manufacturer’s continuous output, surge output, battery capacity, maximum solar input, solar voltage/current limits and other product specifications.
Simple explanation
Understand Your Solar Recommendation
You do not need to know the technical terms before using this calculator. We calculate them from the appliances and usage you enter.
Why did the calculator give me this result?
Your appliance choices and usage determine the daily energy and the maximum power the system may need. We then estimate the inverter, battery and solar panels needed for that plan.
Learn the technical details
Your result is a planning estimate. Actual equipment can change with appliance ratings, starting power, sunlight, battery specifications, shading, wiring and installation conditions.
