Power Station Calculators & Tools
One shared, transparent calculation engine behind every specialized tool below — the same formulas, the same real catalog, applied to your specific use case.
Every calculator on this page uses the same underlying engine: continuous output, daily energy, usable capacity, reserve headroom, and a deterministic product-matching step against the live catalog. A specialized tool just pre-configures that engine for one situation — fixing a fix to the shared math updates every tool at once. See About & Methodology for the full formula set and assumptions.
General tools
Power Calculator
The general-purpose calculator: add any mix of devices, set usage and runtime, and get an explainable capacity/output recommendation from the full catalog.
Open →Power Setup Studio
Visualize how energy moves through a solar-charged setup in real time — pick a scenario, switch devices on and off, and see matching stations.
Open →Solar Charging Calculator
Estimate how long a solar panel takes to recharge a station's battery, with reference tables by capacity and panel wattage. Lives inside the solar charging guide, not a separate page.
Open →Comparator
Line up to four power stations side by side, with a PowerMatch Score where the underlying data supports one.
Open →Specialized calculators
Each one pre-loads the presets, hard requirements and result fields relevant to one use case, so you don’t have to configure the general calculator from scratch.
Refrigerator & Freezer
Recommended minimum capacity ≈ (daily energy in Wh × days of outage) ÷ usable efficiency × (1 + reserve). Enter your refrigerator's running watts (or daily Wh), how many hours a day it effectively runs, and how many days you need it covered — the calculator below does the rest and shows which catalog products actually meet the requirement.
Open calculator →CPAP
Estimated nights ≈ (station capacity × usable efficiency) ÷ (CPAP watts × hours per night). Enter your machine's own consumption (from its label or power-supply spec), add humidifier/heated-tube draw if used, and the calculator shows Wh needed per night and how many nights each catalog product could realistically cover.
Open calculator →RV & Van Life
Add every device you run in the rig with its watts, quantity and hours/day, set how many days you'll be off-grid, and optionally enter a daily solar contribution. The calculator sums continuous and surge demand, nets out solar from the daily energy need, and shows which catalog products meet it — including a hard filter for a native TT-30 outlet if you need one.
Open calculator →Starlink & Connectivity
Daily energy (Wh) ≈ average watts × hours of use per day. Enter your own measured consumption if you have it, or pick a clearly labeled example profile, set how many days you need to run without recharge, and the calculator shows the capacity needed and which catalog products can deliver it.
Open calculator →Home Backup
List your essential home loads with their watts, quantity and hours/day, mark which ones can run at the same time, set your outage length and any solar recharge, and the calculator shows the capacity and output you need — plus which catalog products meet 240V, TT-30/transfer, or UPS-style requirements you flag as required.
