Understanding RV Power Systems
An RV power system consists of several key components working together to provide electricity when you're not connected to shore power. The main goal is to have reliable, sustainable power for all your appliances and devices.
12V DC System
- Powers: Lights, water pump, vent fans, USB ports
- Runs directly from batteries
- Most efficient for RV appliances
120V AC System
- Powers: Outlets, microwave, TV, laptops
- Requires an inverter to convert DC to AC
- Used when shore power or generator is available
Pro Tip
For the best RV power system, invest in a quality battery bank (LiFePO4), MPPT charge controller, and pure sine wave inverter. This combination provides the most reliable and efficient power.
