Instructions for how to remove and reinstall the inverter in RoamRig power systems (all stages)
Before beginning the inverter swap, remove the cushions and plywood from the top of the bench seat. Here's how.
Step 1: Remove Inverter
- Remove fuse cover from front of bench seat
- Turn off all breakers (batteries, DC panel, and solar/stock alternator)
- Remove seat cushions and plywood to expose batteries
- Remove 5 philips screws to release the wooden panel from the bench seat.

- Using two 7/16” wrenches, remove 4/0 ground wire from the ground bus bar.
- Using a 17mm open ended wrench, loosen bolt holding negative bus bar to shunt.
- Using a ½” socket, remove nuts holding bus bars to the inverter.
- Push the negative bus bar down and away, off of the stud on the inverter.
- Using a good condition ⅛” hex wrench (better is a socket with extension), remove 4 bolts holding inverter to frame. NOTE: if you use a ball end wrench or one that is NOT sharp, it runs a GREAT risk of stripping bolt bolt heads making inverter removal very difficult.
- Lower inverter onto ground and remove green trigger wire from face on inverter.
- Lay the inverter on the floor with the outlet facing towards you.
- Using a #2 phillips screwdriver, remove the 4 phillips screws holding the GFCI outlet on the inverter.

- Remove wires from the inverter.
- Reinstall outlet cover with four phillips head screws.
Step 2: Installation
- Remove 4 screws holding outlet on inverter with #2 screwdriver.
- Slide in one wire at a time and tighten terminals accordingly.
- Be certain the correct wires go into the correct spot with previously marked wires:
White wire goes to N for “Neutral”
Black wire goes to L for “Line”
Green wire goes under the phillips screw - Tighten strain relief connectors with a number 2 square drive or flat head screwdriver.
- Screw in top left screw into the frame 2-3 threads.
- Hold the bus bars away and slide the inverter into place.
- Connect green trigger wire into the “Digital Input” slot on the face of the inverter.
- Slide inverter onto bolt threaded in from Step 5.
- Screw in top right screw 2-3 threads when inverter is in place.
- Screw in remaining bolts, lifting the inverter if the holes do not line up.

- Put a flat washer, lock washer and nut holding on the positive bus bar to the inverter.
- Slide negative bus bar to inverter and put flat washer, lock washer and nut on.
- Tighten ½” nuts to approximately 10 ft lbs.
- Tighten 17mm bolt on shunt to approximately 10 ft lbs.
- Reinstall negative 4/0 onto negative bus bar (if equipped with a second alternator).
- Slide wooden panel behind corner trim while holding up top trim.
- Push the wooden panel close to the frame.
- Lift the wooden panel and push in at the same time, when you feel the lower clips are clear, slide the wooden panel back down to the floor.
