Totally. Thanks.

Huh. Well, much appreciation for some of your directions, though I guess those schematics are not much use to me ?. Other thoughts on a diagram (simple DC-DC alternator charger + battery + BatteryProtect; MPPT as an option) ? Just confirming, I guess I'm fairly confident a BatteryProtect...

I think I might be dumb, but the 'out' is going to the batteries in that schematic, which is not what we have been discussing, and indicated as unsupported in the manual?

Yes, I have one and the printout manual. There’s nothing out there specifically like a typical system (even a simple one with an alternator charger or even that, plus an MPPT), but it does seem obvious anywhere before the loads (yes, except with an inverter).

Any diagrams showing where in line the BatteryProtect can be? Right after the battery or in line with the DC-DC charger would be fine (as long as in-->out is setup in the right orientation)?

I never found an answer to this but a DC-DC charger in parallel ("behind" the loads) would be fine (ex.: DC-DC charger connected --> to battery, (then distribution or direct) --> to the BatteryProtect and then --> to the loads)? Thanks! (with the appropriate fusing in the right places, etc.)

I’m doing this in phases, so it’s just a rooftop tent and the components (diagram above); they will be temporarily mounted for a season or two for a fridge and lights. Eventually it will be a cab-over type like Super Pacific or others. Once the camper is in place, I will go to the second phase...

I will eventually and did plan on either converting the wiring and remounting all the components anyway, and potentially going 24V.

Reusing this throwaway post to put up a draft of the diagram with actual components, perhaps not exactly the orientation, but roughly. It’s definitely a temporary layout as more components and wiring get upgraded.

Duh, brain lapse on fuses! Thanks for the reminder.

I looked at the Explorist Life's diagram as the penultimate version I'd build out (and be able to move to a van or whatever scenario). That version has a Multiplus, solar arrays, and AC/DC outlets. For now, I'm trying to go lean, so help me validate my meager build: 100Ah Litime (can add...

Nothing definitive; Bluetti referred me to their D0505S charging enhancer, which I suspect is because that input is expecting 25-27V, which you could supply with a DCDC converter. All in all might not be worth the effort — though I suspect others may be wondering “why not?”

I suspect the EB55 connector is a DC7909, but does it have the (strange) requirement that's needed to function like the other models (shunting pin and inner sleeve(?))? Anyone have a way to connect the EB55 to 12V via that connector? I'm considering building a DC7909 cable to Anderson or to MC4...
