Plugging 50amp into 15 amp house power

July 31, 2021, 07:01:39 pm

I have a 2018 45Ft Cornerstone and I need  answers to 2 questions.
1. When not using and parked at home, what if anything in the bays must be left on in order for the solar system to keep batteries charged. I have turned off the both chassis disconnect switches and the all the house disconnect switched located in the bays. I wonder if the inverters must be left on.
2. If I turn everything off in the coach, including the bay disconnect switches and plug into the house 15 amp receptacle will batteries charge? Also if I want to just operate the electric refrigerator for one day before leaving on a trip to stock up, will plugging into a 15 amp service be okay as long as the house circuit does not trip? If I turn the refrigerator off can I leave the RV plugged into a 15 amp circuit for an extended period of time?

Solar does not care what the Inverter/Charger is doing. If there is sun it will charge. The 200 Watts of solar will not do much more than maintain battery condition.

When plugging into 15Amp outlet, make sure all high draw items are off. If using the charger portion of the Magnum only turn it on and not the inverter portion. Set shore power setting to 5 Amps. You should be safe to run that and fridge.

thanks for your reply.

How would I only turn on the charger and not the inverter. I have a duel inverter/charger. In the coach interface, when I drill down into the details of the inverter settings I don't see where I can turn off the inverter only. Is this something that has to be done at the psychical inverter located in the bay?

If yours has an iPad operated system, I don't know. If not you can use the Magnum Inverter/Charger remote, usually mounted over the doorway. There are buttons to turn the inverter or charger on or off separately.
