Outlet Configuration and Connectivity
The Aceup Energy 4000 watt inverter generator offers a versatile outlet layout suitable for home, RV, and outdoor use.
Available Output Ports
- One 120V AC 20A outlet
- One RV receptacle
- One 12V DC 8.3A car charger outlet
This configuration supports a wide range of devices without requiring additional accessories.
Included Power Plug Adapter Explained
A key inclusion is the 30 amp NEMA TT-30P adapter, which enhances RV compatibility.
Adapter Functionality
- Converts a 30 amp 120V TT-30R generator socket
- Outputs a 30 amp 125V L5-30R RV socket
- Allows direct RV power connection
The adapter is UL498 certified, ensuring compliance with recognized electrical safety standards.
Parallel Capability for Expanded Power
The generator is parallel ready, meaning two identical units can be connected to increase available power output.
Benefits of Parallel Operation
- Doubles available wattage
- Provides flexibility for future power expansion
- Reduces need for a single large generator
A parallel kit is required and sold separately.
