Power station runtime calculator
Estimate runtime from capacity, load, efficiency, and duty cycle.
Planning tools
Portable power calculations with the assumptions left visible.
Choose the calculation that matches the unresolved constraint. Every tool exposes its assumptions and keeps capacity, output, voltage, and starting demand separate.
Use the tools in decision order
Measure the load, model the energy, then compare the hardware

Open tool
Outage load planner
Build a critical-load list and total its energy demand over time.
Solar recharge calculator
Estimate recharge from panel size, station limits, efficiency, and peak sun hours.
Surge watt calculator
Check motor and compressor starting demand separately from running load.
Power station comparison
Compare source-reviewed capacity, output, solar input, weight, and price.
Power station sizing wizard
Turn load, hours, outage duration, efficiency, and reserve into a capacity target.
