In the recent Champion Generator propane adapter thread I alluded to "issues" with running the generator in my Victron-equipped 315RLTS. This post will attempt to document the issue and steps to overcome the problem. In a second post I'll post performance data.
I know this information will only apply to a small subset of owners...but since I need to document this for myself to remember the settings(!)I thought I'd share the info.
PROBLEM
No 120vAC passed to the trailer from a running generator.
1) On the CCGX change the Multiplus' SWITCH state to OFF
2) Change AC INPUT 1 from SHORE POWER to GENERATOR
3) Change Multiplus' Input Current Limit to 13.5A*
For those who may not understand this setting--it tells the Multiplus how much current is available from the source. Normal shore power limit is 50A (at a campground, etc). The Input Current Limit setting keeps the Multiplus from demanding too much power from the generator.
*13.5A had the scale on the generator flashing 100% output (on and off). Pic below. This meant the output was just below 100%--there was likely a bit more capability left because the outlet symbol was still green (a red outlet symbol indicates overload). I could have gone to 14A, maybe even 14.5A, or possibly even 15A on the Input Current Limit? I didn't want to push the generator too hard for an extended period. The electrical math wizards here will calculate that 13.5A is 1620W. The propane rating of the generator is 1800W. Again, my choice was to be a bit on the conservative side.
4) Ensure the generator is NOT in ECO mode (should be running at full power).
5) On the CCGX change the Multiplus' SWITCH state to ON (reverse steps shown in step 1)
After a moment the inverter will show power coming from the generator.
Questions? Fire away...

PROBLEM
No 120vAC passed to the trailer from a running generator.
- Bonding plug installed
- 15A to 50A Adapter installed at generator
- Progressive Electrical Management System (EMS) was showing 120v on both legs and the display was showing "E0" (no faults)
- Tow/Shore switch set to "Tow" (all circuits available in trailer on the inverter--a highly specific mod I did to my trailer)
1) On the CCGX change the Multiplus' SWITCH state to OFF
