I have searched but cannot find how AC2 out and power assist is handled. Assuming using more load than shore power can supply, how is power split between AC1 and AC2? Does AC2 get 100% of what it needs and only AC1 gets assisted? Probably only happens very rarely, but what if AC2 load exceeds available shore power?
AC2 is just a feed from AC1 with a relay that disconnects it on grid loss, behaviour that can be overridden with assistants
It is not a separate bus and is not separately metered.
Look at the block diagram in the manual.
I have a 50 amp RV with a MultiPlus-II 12/3000/120-50 that I would like to wire half of my panel to provide non-essential loads utilizing the AC2-Out relay. The problem I have is that when switching from shore power to Inverter, the Inverter overloads if both AC units are on at the time of a shore power failure. I am considering wiring L2 of the panel to the AC2-out. My question is; Do I need to bond the neutral and ground to AC2-out or can I just connect the L2 wire to this connection from the breaker panel? I’m assuming the Neutral and Ground are internally bonded? Also, Does any one have any recommendations for settings of the AC2-out assistant in VE.config. I currently have two programmable relays set for AC2-Out to close relay with AC-input (after 120seconds) and open relay with No AC input (after 1 second).
