GridSpec’s power-system compatibility sizer
A free sizer estimates whether a power station or battery can run an appliance or EV load, including runtime, solar recharge, and electrical sizing.
- For
- Portable-power and home-battery owners comparing loads
- Worth noticing
- The region switch changes voltage, wire-size, and plug assumptions between North American and UK/EU/Australian standards.
Field notes
The interface starts with two selectable lists: a power station or battery system, and an appliance or EV charging load. Its regional switch changes the displayed electrical context, including voltage and wire-size conventions. The page describes runtime and solar-recharge estimates as well as continuous-load, surge, breaker, and cable checks. It names NEC 2026 and UL 9540, but the supplied extract does not show how the calculations are sourced or validated.
