is my idea doable ?

EG4 6000xp hooked to 18 Hyperion 395W bi-facial solar panels, 9 per MPPT, currently 2 EG4 Lifepower4 version 2 batteries
This for 90% of the time on the house.

the other 10% of the time

Then move it to a step van, Chevy Chassis, small block motor, fuel injected, alternator no clue, with 6 panels feeding 1 MPPT & thought 1 battery but I'm thinking at a minimum 2 batteries
now. Will be powering a 120 volt EG4 9k mini split 190 - 1000 watts,120 volt lights,120 refrigerator, phone chargers, wife wants to change to a star link since
our internet sucks out here in the country anyways.

My main 2 goals is to be able to sleep at night comfortable, & be able to leave 2 dogs inside while AC is keeping them comfortable while we
do a few stops that are not dog friendly.

Now writing this the mini split will be the only AC on the step van so on hot/humid Texas days or elsewhere cooler/cold nights it would
be in the on position most of the time. (will have a supplement heat source be it diesel or propane) so not real concerned about heat at night.

thinking of having 2 panels hidden under others, will 4 panels exposed to the sun driving down the road be sufficient ?
395 x 4 = 1580 / 12 = 131 volts feeding 1 MPPT = near the bottom limit (if my math is right) or do I need
to get 6 panels exposed to the sun while driving ? 395 x 6 =2,370 / 12 = 197.5

or supplemental charging off an alternator ? what type, how many amps are suggested & I see mention of an isolator somewhere in
Isolator, I see Battle Born has information I need to read up on.

If I need 6 panels exposed the roof rack will act as shade over the windshield I guess.

Suggestions / advice please

Thanks in advance
 
I recommend a separate 48v RV system, and you move just the batteries.
You can get RV 48v AC and fridge that can run directly off batteries. 48v to 12v converter for everything else.
add a charge controller to charge battery from panels.
Don't know about options to charge a 48v battery with a 12v alternator. Some type of boost circuit is needed.

Alternatively, build one 48v battery with 4 12v batteries, and have a 12v RV system.

Appreciate the information, guess I should mention I already have the components, 120v mini split, 120v dorm room
size refrigerator, 120v micro wave,
48 volt equipment is already purchased = 1, EG4 6000xp inverter, 2 EG4-LifePower4 V2 batteries, 6 Hyperion 395w bifacial panels.
So not really interested in buying additional items especially 12 volt powered items other than a larger alternator &
& a way to charge while driving (IF POSSIBLE)

Why a separate system, 90% of the time it will be on the house, why not just unplug & move to vehicle ?
doesn't make money sense to me to invest in equipment that will sit idle for 8-9 months.

1)I see 48 volt refrigerators for $1900.00 TO $2600.00 [ my free small dorm room was free and works just fine ]
2) 48 volt mini split $2,135.00 [ my EG4 9000BTU unit from signature solar was $1,149.00 & its 120v input ]
3) didn't a 48v microwave [ my microwave was free ]

You mentioned charge controller
4) the EG4 6000xp already has built in charge controller.

Seems to me running simple 120 volt appliances are much cheaper, easier to locate if something breaks

Again thanks for the insite.
 
In my case, I would not consider moving the inverter between the house and the RV. The time involved to uninstall/install the unit, along with the hassle of carrying it, would make this cost prohibitive. I keep my RV pretty much in a "ready to roll" state. In about an hour I can be on the road headed to some remote site for camping.

In your case I understand, I was actually asking about my case.
My question is it doable, not concerning the hassle you think it might be
shut the system down, disconnect MC4 connectors, disconnect twist lock plugs, wheel 2 wheeled dolly out to van, load & secure it, plug in MC4 connector, hook up up inverter to breaker panel & turn.
What's the cost ? everything is already purchased.
Carrying it would make it would make it cost prohibitive = that make no sense

Time is money. Over a year or two, the accumulated amount of time to uninstall/install would be more than it would cost me to buy another unit. I'm a consultant. Billable hours pay the bills.

Ever here of twist lock connections, couple minutes to unhook & re-hook doesn't sound that difficult to me.

One person actually had a novel idea, just leave it mounted inside the step van & unhook wiring from van
then hook up to house 18 panels & sub panel.

Spending an additional $4,000.00 to $5,000.00 buy another system (just for temporary use) might fit your life style, doesn't sound
very good for my situation.
using 1 system dual purpose seems much more economical, only thing that would sit idle my way would be 6 panels.


Appreciate your thoughts anyways.

Eg4 3000 is $675. Wire that permanently into the Van. Move batteries as desired.

Main connections for an EG4 6000xp are not trivial. Fortunately you don't have to deal with Grid Power. But, those wires are big, and are supposed to be torqued.
