Hi. I just purchased a charger one to go in my sprinter van and charge my Goal Zero yeti. Well it doesn’t work w the goal zero… I tried it with a different power bank I have and it works and I’m tired of fiddling with it. My yeti is old and I am getting some faults so I just ordered a Bluetti AC 200L with D-40 to install.
I’m trying to figure out a way that I could hook up a three-way battery switch to connect between solar and the charger 1 and the 200L. There is only one input on the 200L. It will be in a tight spot so I don’t really want to be connecting and disconnecting mc4 connectors every time I switch between alternator and solar. Looking at those three position battery switches that have a position one, two and off would work. With those switches you hook the red power wire to it but they don’t have anywhere for a ground wire. Could you just gang all of the black ground wires together because of course all of the wires have a red and a black.
This one I am looking at… Position one and two would go to the solar panel and the charger and the output would go to the battery. What do you do with the ground wires? I hope this makes sense.
Simple, but will work. However, place midi fuses on all of the positive lines.
Solar to Switch - slightly larger than the Amps output of solar.
Charger 1 (10A) to switch - 15A will do if you use 25A cable.
Switch to battery - rated to which ever of the solar or charger 1 is the higher current + 5A.
Make sure the cables both positive and negative are rated to a higher current (Amps) than the fuses. Definitely use a centre OFF switch to avoid any back feed between solar and C1. The one pictured is correct.
You are welcome
I’m not installing my charger 1 into the vehicle as I have multiple uses. However, I have a 30A and a 40A Anderson on the rear bumper as well as a 40A in the rear of the 4x4 (normal use is the Auxiliary battery).
As most of the connections are 50A Anderson plugs, it’s all plug n play, lol.
Finished my install today. Works perfect. AC200L with D40 to run my fuse block (lights, USB ports, refrigerator), charger 1 with a battery selector switch to switch between charger and solar. Really happy with how it all worked out. Do wish there wasa 90° plug available comimg out of the 200L.it pokes out a bit. Installed in sprinter van.
Nice install, You could perhaps use the surrounding area to make a stand off over the plug. Yes it may stick out a little further, but at least it might stop the plug from being knocked and possibly break.
Make a suggestion to Bluetti about a 90 deg plug, you never know…
A suggestion for you… Get some P clips or similar and fix the switch cables to the wall. As you’re mobile they will swing around. Or similar to the tie in your bottom pic, but I’m not a fan of adhesive ties in a vehicle especially here in Australia, the heat aint kind, lol.
All good advice. I had to look up p clips. Yeah that would be better. The AC 200L sits underneath the bed area so not a huge amount of traffic but I do crawl around down there sometimes in the dark! I would hate to break off that cable for sure. I’ll email them.
