The parking power system is a dedicated electrical solution designed for travel scenarios such as RVs and vans, capable of continuously powering living appliances after the vehicle engine is turned off. Its core utilizes lithium iron phosphate (LiFePO4) batteries known for long cycle life and high safety, integrated with an intelligent management system that supports multiple charging methods including driving, mains power, and solar energy. The system delivers 220V AC output via an inverter, safely and reliably operating appliances like air conditioners and refrigerators. Distinct from starting batteries, it significantly enhances both powerautonomy and safety for outdoooutdoor living.
