Magnum 3000w inverter in 50amp system
Hello, If I go the expensive route I will install a Magnum MSH-3012-M Hybrid PSW inverter/charger. I would want the ability to run the entire RV (not all at once of course) via this unit so would ha...

Of course what you have described is the so called easy part of your install.
I think your 3000WATT INVERTER will need around 250AMPS DC Current to operate it at full load which has to come from your battery bank. I notice the spec sheet calls for a 400AMPS DC source to be used. This is some serious capacity requirement.
You will need to install several batteries in your battery bank to handle this very large load even for just a few hours. Also when you increase your battery bank capacity then you also have to increase your ON-BOARD Charging system to be able to recharge the battery bank in the desired time you want to the battery bank to return back to a usable charge state.
Alot of planning will be required in this area as well. The only real time example I can offer from experience is I had to load down a 1500WATT Inverter with test equipment on one Antenna field repair test we were involved with back in my working days. All we had was a rental car with it's single probably a 105AH battery in it. We fired up all of the test equipment was wanting to use which just barely added up to a full load of 1500WATTs. They all fired up normal but only lasted about 15 minutes before running the rental car battery down to a full discharge.
1500WATTS operated by a 12.3VDC source would represent around a 120AMP DC LOAD (not counting losses). 120AMPS is half the current load of the 3000WATT Inverter so this would drain the 105AH battery in about 7 minutes all things being equal. If you are wanting to run your trailer setup for 8-10 hours like most of us want to do you are going to need many 12VDC batteries in your battery bank... The manufacture wants you to install a 400ADC battery source which will include larger battery cables and a much larger setup to give you a more reliable system to use.
Just passing along to make sure you are understanding what you may be up against for the 3000WATT INVERTER install.
