I initially plugged my 5er power cord into my inverter, but found it somewhat of a pain when traveling where we moved often. I also found myself getting old and forgetful when it came to turning flipping the DC converter circuit breaker. I ended up putting in an auto transfer switch so I wouldn't have to deal with the cord, and I put a SPDT ac relay in the circuit for the DC converter that I use as an isolation switch to turn of the DC converter if the inverter is powered up. Easy and brainless seems like the way to go as I head into retirement.
