Size RV solar wire by voltage drop, or check an existing AWG size with volts lost, percent drop, watts lost, and mm2 area.

Choose an RV charger amp size using battery Ah, 12V loads, recharge time, battery type, and wiring limits.

Estimate RV generator watts from appliances, startup surge, buffer, altitude loss, and 20, 30, or 50 amp RV service limits.

Check RV 50 amp shore power loads by watts, hot side, voltage, reserve watts, and breaker headroom.

Check RV appliances against a 30 amp hookup, including watts, amps, headroom, long-running load, and startup peak.

Check RV shore power load for 15, 20, 30, or 50 amp hookups, including 50 amp leg balance and steady-use target room.

Add RV appliances, startup watts, battery voltage, and Ah to estimate inverter size, surge rating, battery amps, and runtime.

Estimate EV charger voltage drop, load voltage, wire heat loss, monthly loss cost, and a voltage-drop-only wire size.

Check panel room for a Level 2 EV charger, including 125% load, breaker size, and a lower setting that may fit.

Estimate shared EV charger amps, kW, overnight kWh, miles added, and whether each car meets your minimum useful current.
