“It is easier and much less expensive to use less electricity than it is to create and store gobs of it.” – Sternwake
Access and use of electrical power is crucial to RVers, whether plugged into RV park hookups or boondocking off-grid.
Shore power feeds the converter and any 110v circuits in the RV. High amp draw appliances like electrical heating and air conditioning are only practical on shore power.
RVs usually have more than one battery; these are divided up into starting and house batteries. Starting batteries are what is used to start a motorhome or towing vehicle engine. House batteries power the living area.
An inverter can be used to turn 12v DC into 110v AC.
Dual-battery systems use the alternator to charge both the house and starter battery. An isolator or solenoid is used to keep the house from depleting the starter battery.
