How does ROYPOW all-electric APU unit for truck system work?

ROYPOW 48 V all-electric truck APU system captures energy from the truck alternator or solar panel and stores it in lithium batteries. The energy is then converted into power for your air conditioner, TV, fridge, or microwave to let you get the most out of your sleeper cab. 

To guarantee unstoppable power at any time, this 48 V APU unit for truck system can be connected to multiple charging sources: when a semi-truck parks at a travel stop in a short time, shore power can charge the lithium-ion battery and starter battery through the all-in-one inverter and also supply power to all connected loads; when a semi-truck is on the road, the robust 48 V intelligent alternator comes into play, swiftly charging the battery pack in approximately 2 hours; when a semi-truck is parked for extended periods, solar power through the all-in-one inverter can efficiently charge both the LiFePO4 battery and starter battery to prevent restart issues. Truckers won’t need to resort to diesel power, minimizing fuel consumption and costs and lowering the carbon footprint.
