This page is the van-specific installation sequence for the current electrical MVP. It turns the accepted electrical design, purchased hardware, and recovered official installation documents into one ordered procedure from an empty rear electrical bay to first-power-complete MVP status.
It is not a replacement for the official manufacturer manuals. Use it as the build-order, verification, and closeout page for this van.
Use Van MVP Installation Instructions as the parent procedure for the full cross-system MVP path. This page only owns the electrical subsection of that larger sequence.
This procedure covers the current electrical MVP only:
24V 460Ah house battery bank from the two Epoch batteries301EL-B -> 8077 -> MultiPlus -> 8027150/45This procedure does not treat these as required for MVP completion:
2x Orion XS 140024V -> 12V service zonesUse these as the controlling install references behind this page:

8077 upstream main are installed8027 panel is installed with branch 1 ordinary outlets and branch 2 induction allocated50 in x 30 in backer.8077 mounts inboard of the 301EL-B on the rear utility wallThese are the remaining physical inputs that this page cannot invent:
| Field-closeout item | Why it matters | Canonical owner |
|---|---|---|
exact rear chassis-bond landing point within GP29-31 or a fixed-body fallback |
closes the final DC bond location and vehicle-side lug fit | Measurements |
exact 301EL-B -> 8077 -> MultiPlus conductor path |
closes the real AC feeder sweep and protection geometry | Measurements |
| exact MultiPlus DC positive/negative routed path | closes the final 1/0 AWG run length and lug orientation |
Measurements |
exact first-device GFCI location and the branch-1 ordinary-outlet grouping |
closes the first AC branch execution | Measurements |
The install order below assumes those items will be captured before final crimping or final branch-box closure if they are still open at build time.
Before mounting anything, physically stage and verify:
5119, 9003e, 8077, and 8027150/45301EL-B1/0, 10/3, 12/3, and 14/3 cable stock already documented7748, 7721, 2104, and 2718 hardware only if it is still physically present and not yet handed back to AmazonDo not start cutting cable until all major components are on hand and dry-laid.
Install or confirm the rear 50 in x 30 in backer as the upper electrical service field.
Keep these package intentions intact:
9003e near the rear-door edge for immediate shutdown access8027 and MultiPlus on the AC/right-side bandDo not final-drill component holes until the batteries, MultiPlus, full Lynx stack, and 8077 relationship have all been dry-fit together.
Before any permanent mounting:
#1, and Distributor #2 in the current lower-left spine order.9003e where it is reachable from the rear-door side.8027 beside the MultiPlus.At this stage, confirm:
9003e can be operated without reaching across live equipmentThis is the standing AC-input sequence:
301EL-B cutout.2-7/8 in hole basis.301EL-B on the driver-side utility zone.8077 on a fixed serviceable surface immediately inboard of the inlet before the feeder turns toward the MultiPlus.Keep the Blue Sea 10 ft shore-inlet protection rule intact. The current design intent is that the 8077 is the upstream main, not a distant downstream convenience panel.
Do not terminate the AC feeder until the actual 301EL-B -> 8077 -> MultiPlus path has been confirmed.
Mount the heavy-DC backbone in this order:
9003eThe exact positive-side cable order is:
The exact negative-side order is:
Use the current ordered lug families and keep the current 1/0 AWG assumption for the short rear spine unless real installed routing proves otherwise.
With the hardware mounted and the battery restraint package ready:
12V batteries to create the 24V bank.5119 300A Class-T fuse in the main entry path.9003e and Lynx backbone package.Do not connect the final battery leads until every downstream heavy cable is dressed, supported, and ready for staged energization.
Install the current exact branch fuse set:
300A MEGA for the MultiPlus branch60A MEGA for the passenger feeder branch60A MEGA for the mini-split branch position40A MEGA for the roof/center feeder branchEven though the mini-split is not part of MVP energization, keep the current branch position documented and physically legible if the branch space is being built now.
Label each populated Lynx branch clearly by destination before closing the assembly.
The current direction is a short direct rear-zone run from the Lynx area to the MultiPlus.
Procedure:
1/0 AWG positive and negative runs only after the routed path, bend sweep, and service slack are proven.Current source-backed assumption:
1/0 AWG is the minimum accepted band for the current short-run layoutThe current MVP backbone does not require the external 2104 busbars or the old Blue Sea charge-combiner package.
Use the system side of the Lynx stack for:
#1#1#1 dedicated ground connection for the main DC chassis bond60A charge-source branch on Distributor #2#2Do not reintroduce the return-approved 7748, 7721, 2104, or 2718 hardware into the required build unless a later source-backed architecture change deliberately reopens that hardware family.
The current roof-entry architecture is one shared roof-entry cluster using the purchased junction-box strategy.
Roof-entry sequence:
150/45 in the upper-middle charge field.60A charge-source branch using the documented 6 AWG branch family.This page does not close the portable-solar path. Keep that fully separate.
The accepted AC stack is:
301EL-B -> 8077 -> MultiPlus AC-in -> MultiPlus AC-out-1 -> 8027
Procedure:
10/3 feeder from the 301EL-B to the 8077.10/3 feeder from the 8077 to the MultiPlus AC-in.8027.8077 after the wall finish and backer area are closed.Do not improvise a different upstream-main order. The current accepted architecture depends on protecting the feeder before the 8027.
The current MVP branch allocation is:
1: 15A GFCI/general outlets2: 20A induction3: spareCurrent GFCI direction:
GFTR1-W on branch 1Current ordinary-outlet zones:
Current minimum branch work for MVP:
1 first box location14/3 ordinary branch cable family to the branch-1 outlet chain12/3 induction branch to the induction location3 spare unless the final outlet package deliberately changesDo not lock the final box count or the exact first-device location until the package-position capture is complete.
Current accepted grounding direction:
Procedure:
1/0 AWG bond cableDo not use a rear door, wet floor edge, or improvised thin-sheet attachment point for the main house bond.
Before any energization:
Use a staged bring-up, not one all-at-once energization.
Recommended sequence:
9003e open and confirm no unexpected load behavior301EL-B and 80771 ordinary outlet chainIf any grounding, polarity, heat, smell, or nuisance-trip behavior appears, stop and correct it before proceeding.
These are the main remaining gaps that this page cannot close from current evidence alone:
| Gap | What this means for installation |
|---|---|
exact Ford GP29-31 bond point not yet field-captured |
the main DC bond should not be finally crimped/landed until the actual stud and lug fit are confirmed |
short local 301EL-B -> 8077 -> MultiPlus path accepted, but exact cut length still field-held |
user physical direction now keeps the shore inlet immediately behind the backer with the 8077 close to the MultiPlus and the total AC path within about 5 ft; do not final-cut the feeder until the exact sweep and service slack are marked on the van |
| short local MultiPlus DC path accepted, but exact cut lengths still field-held | user physical direction now keeps the MultiPlus in the same rear zone as the Lynx stack with DC runs expected within about 3 ft; keep the current 1/0 AWG direction and finalize only after the real cable sweep and slack are marked |
exact protected-positive jumper geometry around the 9003e still field-held |
the current no-busbar backbone keeps the switch in the protected positive path, but the final direct-coupled-versus-short-loop execution still needs real package confirmation before final heavy-cable cutting |
| first-device GFCI zone accepted on the rear backer, but exact box offset and outlet grouping still open | branch 1 first-device location is no longer a topology blocker, but cable lengths, first-box hardware, and any later branch-3 split still depend on the actual outlet grouping capture |
If the build is happening in the bay and you need the shortest ordered checklist, use this:
