Super Portable system, am I missing something....?

[Moretorque]

Does this make any sense and what else will I need. Building 2 1000 pound rated 4 wheel hand trucks with 1 XP 6000 and 2 EG4 48 volt rack batteries on each on and then have a 4 wheel cart with like 500 pounds of batteries on it that I can load in a truck with a winch in a moments notice. Can Thie be made to be practical ? What all do I need that I am not seeing, i know very little about this stuff so thanks... I bought a bunch of 10 gauge extension cords to go with it, any input would be great....

Two carts
each with and EG4 6000 and two rack batteries (100Ah batteries? or 280Ah batteries?)
What else do I need - depends on what you want to do with them.
First up - what will let you plug in any of those 10 ga cords - you need a panel and plugs and cable to connect the batteries to the inverters and the inverters to the panel you build. Not sure if you know but the battery cables need to be big enough to supply the max amperage the inverter may draw:
6000W/48v = 125A
Every battery should have a fuse,
What are you trying to run? for how long?
Second - two EG4 6000's - are you going to parallel them together?
Not sure about the waterproofness of the EG4 inverter and batteries - ie if they are in the truck box in the rain etc. best to check,
How will you plan to charge these batteries - no solar PV panels in the plan?

This guy has a cool setup, maybe you can get some ideas from this?

Thanks for replying, I am real dumb with this. I just saw where Will made a portable 3000 watt Hand truck system and I decided to do a bigger one without knowing what I am doing. This is what I have and I want to finish this and I want a portable system to where I can just bypass my house system and run this with cords to power whatever I want and be able to tie it into the house if I want but main priority is portable.

I have 2 EG4 batteries, 1 Victron 450/200, 1XP 6000, and 16000 or so watts of panels.... I was doing all Victron but the stuff is not UL rated and somebody in the know told me if your house burns down the insurance will not pay for it so I did not buy anymore Victron which I wanted. Then I wanted to go Schnieder 6048 but it's discontinued with no support so the XP 6000 made the most sense but it is a HF with no real proven track record ? From what I have read the good LF is supposed to be a lot better but the XP 6000 just make the most sense. I guess you would just keep a closet full of them for back up ? So I want to do 2 big Will 3000 wheeled builds but am stumped about what to buy... Again thanks for the replies. Probably just do another XP 6000 with lots more batteries? Can I make this work in a practical mobile sense ?

Do some reading on the forum - lots of mobile set ups have been posted in various capacities.
There are some similar ideas with hand carts like Lithium Solar's

Although trying to make a mobile PV set up is more challenging unless you go to a trailer mounted system.
A few of those on Youtube.

The main thing will be how you plan to interconnect everything, so it can be quickly moved, but also quickly connected/disconnected safely.

Thanks, what about having one solid LF inverter over 2 or 3 xp 6000's

2 or 3 x 6kW is 12 or 18kW - what is available in this scale that is LF - not sure myself.
Honestly I am not convinced the LF is any better than HF for the types of things we are running, however I am going by the comments of those on the forum far more knowledgable about the differences between them.

My own research typically showed LF = more idle current losses, but also depends on the quality of the inverter. Better (low idle loss) is more money in every case I have seen.
