Here is a bit of a crazy situation but I will be installing a pair of Quattro's to run a split-phase system in a rescue vehicle. 48v 25kwh battery bank.
Unit has a 20a shore power inlet and a 30a split phase power inlet attached to a 50ft cable reel that was designed to connect to a generator trailer that we no longer use. While connected to shore power we intend to only use the 20a inlet since that is on the overhead reels connected to AC-in on Quattro #1 and Quattro #2 will not have any AC-in.
The intent is to leave the 30a power inlet connected to AC-in #2 on both Quattros to allow for connection to the generators in case of extended operation. The question is with the use of an inverse "suicide-cord" to turn that cable reel from a power-in to a power-out can the Quattro's back-feed to act as a "generator" if we need to connect something to the rig or do we have to wire a dedicated circuit and carry a generator cable? Wiring the extra circuit isn't the concern but the space to carry the second cable certainly is.
Thanks for entertaining this crazy question!
