Hi Dan,
We just picked up our 2016 BH 3270RS which is equipped with a residential refrigerator as well. I too have the switch that you show in your photo - thanks. I'm assuming you need to manually turn the inverter on after you've disconnected from shore power? I assumed it would be an automatic switch-over. Unfortunately, the dealer knew less than I did when we were going through the trailer on delivery.
From reading other threads in the forum, I was under the impression that if you ordered the residential refrigerator option, it would come with two 1000W pure sine inverters - one dedicated solely for the refrigerator. Mine only has the one... I know there was a 'firmware update' recently on the inverters. Did that take care of the overloading issue when the refrigerator cycled so a 2nd dedicated inverter is no longer needed?
I'm getting ready to install a solar system in the next couple of weeks and I plan to change from the two 12V house batteries to four 6V golf cart batteries at the same time. If the inverter is under-sized, I may need to look into upgrading to a 2000W unit. Any suggestions?
Thanks,
