Leaving trailer plug in when at home.

I think this thread says it all... A multi-stage converter or a Battery Minder.

Only thing I would consider adding is having an EMS hard-wired in, which will stop the RV from frying if plugged into a 240 volt dryer outlet, as well as save the A/C compressor if a CG has too low a voltage. The reason for it to be hard-wired in is that there is no way to forget about plugging it in, and it is out of reach for all but the most determined of thieves.

The issue is with battery charging. If you buy a "charge wizard" module and plug it into your inverter converter charger it will properly regulate the batteries. First thing I installed in my new to me TT and its plugged all the time. My flooded batteries Trojans T125's are still going strong on our old TT 11 years now.

Have fun

JMO, but leave your rig plugged in 24/7 and it's only a matter of time before anyone can become a victim. :(

Yes SoundGuy

I forgot to mention that. My trailer is set up with a GIF protection source. But still a good idea to add a surge protector.

That's why in the U.S., we have building codes and circuit breakers. My 30AMP plug-in has been plugged-in to my coach for 12+ years - not one problem.

:S A....well....that would depend on whether the house batteries are disengaged, or not.....

Well not unless you roll your RV over that is, but not from charging.

Correct! Ding, ding, ding!!!

I store my 'C' in a building that I own about 5 miles from my home. I had a 30A socket installed and leave it plugged in. The building is heated to 45 degrees in the winter, and the MH warms up quickly when I'm working in it. I installed battery disconnects for the house and engine batteries. I have battery maintainers attached to them when its stored.
I actually lived in it for 3 days when the power went out in our neighborhood. It didn't affect the area where the RV is stored.
