2018 Majestic 23 Inverter problem brewing...HELP?

[juiced_vette]

I think I have made a mistake but haven't yet completed it (good thing).

I added another battery to my 2018 Majestic 23A. I then (tomorrow) will add the inverter to it. My plan is to plug the shore power cable into the inverter to have all of the plugs in the RV powered. I just realized that the converter will be ON. So it will then be trying to charge the batteries, which creates a loop which isn't good.

Is there a way to power the plugs in the RV without causing this short? I figured by turning the converter off would solve the problem but now NONE of the plugs will work.............

Am I correct in thinking this? I'm trying to avoid running extra plugs from the inverter to say, the TV or kitchen area.........

Thank you guys!!

Sounds like wrong approach. Usually for adding an inverter to begin it needs to b one that is designed for an RV or marine installation. Ground and neutral bonding also need to be managed. The normal approach is for a branch circuit for feed an inverter or inverter-charger which also includes an automatic pass-through relay. Then the circuits that are intended to be feed by the inverter, get move to the inverter output. Since most RV circuits are either 15 or 20 amp, if the feed through or the inverter output is greater than those circuits then a panel is usually added, fed by the inverter, and then the needed branch circuits fed from that panel.

The trick is to have the converter on its own breaker and flip it OFF when on the inverter. My refrigerator and water heater are on individual breakers as well so that I can turn them off and just run on LP.

If there is room in the panel, you can add a breaker. If not, you can replace one of the existing ones with a dual breaker to get the additional circuit.

Not a problem to have the converter running on inverter power (not a short) just wastes power in the conversion process.

Success! Thank you. I hooked up the second battery under the dinette seat (room for a Group 24, not a 31), and hooked up the Renogy interter. Plugged in the shore power cable to the inverter, turned off the converter breaker and hit hit the power on the inverter. All of the plugs are powered.

So for our Nashville trip, kids can charge phones and watch TV on the move.

Thanks!!!

Are you saying that you added a battery (lead presumably) INSIDE the RV in the space that is located beneath the bench that you sit on? If so, how is the battery vented to the outside world? Lead batteries will off-gas while charging and if this is happening basically inside your RV (...the gas will permeate into the RV) it could be a dangerous/unhealthy thing.
