Acceptable solution
It turns out that there is no inverted power to the distribution panel over the driver's seat. The only connection for the inverter/charger in that distribution panel is the 30 amp power supply for the charger.
Rather than taking time to try track the output lines from the inverter, the tech and I agreed that an acceptable solution was to simply tap into the outlet dedicated to the microwave. The microwave is immediately adjacent to the refrigerator in the slideout. It was easy to run a romex feed behind the microwave into refrigerator compartment.The refrigerator and microwave both seem to run fine on the same circuit without overloading the circuit (tripping the breaker on the inverter).BTW, I learned that all the outlets connected to the inverter are on one circuit and the microwave was the sole connection to the other inverted circuit.
The Bi-directional Isolator Relay Delay (BIRD) and the Isolator Relay (Trombetta) function beautifully to keep the house batteries fully charged from the alternator while the engine is running so, by leaving the inverter on constantly, the refrigerator runs fine while driving, plugged in to shore power, running the genset or straight from the house batteries. I haven’t tested duration while only on batteries (4 x 6v lead acid); others have suggested that 12 – 14 hours should be no problem, depending on other battery loads, of course.
About 2 hours to do the job, start to finish. I could have done it myself.
Take care,
Stu
