Hear me out, new to the AC side of stuff but have been pouring over grounding/bonding threads...without a conclusive answer.
I just installed a mulitplus in a truck camper and the RV AC panel is unbonded (as it should be). The multiplus is set to use the ground relay when inverting, but not when AC in is detected (because the shore source is bond point). Peace of cake, thought i was done there until i continued following the bonding threads.
If I plug a portable generator into the AC in, it leaves my entire system unbounded. Could the second AC input on the quattro operate the ground relay and give a bond? Or should the bond be present at the portable generator? Is there an appropriate transfer switch that can provide the bond for cheaper than purchasing a quattro vs multiplus (i am not upgrading my inverter anytime soon)
Current plan is to just build a bond plug for the generator, but i prefer these things to be more foolproof as i am not the only user. This may only be an issue for smaller RVs that do not have built in generators. I would expect the built in generators to deal with the bonding issue internally or in the transfer switch.
Was considering a blues seas rotary switch and bonding the generator input side of the switch at the switch. So shore would pass unbonded to the mulitplus and flipping to generator would be bonded.
Could I control the ground relay in the multiplus with an external switch via cerbo or multiplus relay? (still not a foolproof design)
Woo, hope that made sense...
