When I'm parked, plugged into shore power and I'm plugged into the inverter outlet in the refrigerator compartment, is the electricity coming from the shoreline or from my batteries?

I guess I'm asking if I am draining my batteries with the refrigerator (or other appliance) by being plugged into an inverted outlet and replenishing them at the same time with the shore power or am I bypassing the batteries since I'm plugged into shore power?

Additionally, if it's coming from the batteries, should I switch to the shore power outlet to keep from running on them?

I hope my question makes sense.

Can't say for your coach and don't even know what you have, but with ours, there's a pass through feature with pretty much the whole house outlets. The exception being the block heater, which is shore only and one of the two outlets behind the fridge, which is shore only. Either way, shouldn't be a biggie and just like with our old coach and whereas I installed a separate inverter and ran some outlets. Consequently by doing this and if they were in use, when hooked up, the batteries would be replenished continually, by the converter/charger.

I wonder if the new solid state relays have contacts to burn?

I prefer to unplug so as to NOT switch under load. In some ways I wish my Magnum inverter did NOT have a transfer switch built in. I do take some comfort that the switch is rated for 60 amps and I'm in a 30 amp RV.

Yet, I've seen Cameco female outlets "burn" when used on a 15 amp shore power supply, even after being treated with deoxit. I won't even buy them any more. The male Cameco seem to work just fine.

If your inverter is off will your batteries still charge? I am new to the class A R V they are a lot different from the truck campers I have had until now. sorry to cut into the thread but maybe the op might need to know also.


You need to post the Brand and Model of Inverter and year/brand/model of RV. In simple terms, IF you have an Inverter/Charger, and you turn the Inverter OFF, only the Invert side is off, the charger remains ON. Since this is a motorhome forum, most motorhomes have an Inverter/Charger, not an Inverter ONLY. Doug

Not an inverter only, but a lot of converter only's. Then there's all the ones with additional and separate standalone inverters and have installed these myself.

BEFORE TESTING:
Ensure air conditioning units and other high current users are switched off.
It is harmful for the transfer switch to switch over power sources while under load.
Shut down all power sources to the RV
Label power sources clearly that testing is in progress.
If accessible, remove the lid of the ATS to visually check function


Are you saying that you have documentation from the ATS manufacturer(s) that state that all power must be removed when switching power sources?


I think you just read it: "from one of the various RV Transfer switch makers"

When did the TESTING section apply to normal use?

Testing is not equal to normal operation.
