Solar and Charger into one?
I am modifying my cargo trailer to be more like a camper, and dug up some old stuff for it. I have a modern MPPT solar controller for the 100 watt (soon to be 200w). Two golf cart batteries. I ha...

Hard to believe how long it took to build the electrical system.
The batteries are two 6-golf in a box. The box is self contained and vented, varnished and will be painted one day.
I used two bolts to get the power through the box.
The metal bracket that is almost painted yellow spanning the styrofoam is the spare tire bracket for the outside (no structure on the nose so made this)
I turned box around to show how the vent works, but this
is the vent system, is a sink drain piece with a lip and a radiator hose section that fits perfectly over. The thin stained piece of wood has a hole cut in it the exact diameter as the black pipe. I used 4 screws and held it to the box (mount not pictured)
Still need to add water pump and plumbing, but most electrical is done.
I am waiting for parts to put the 100w panels on the roof, so still have to run solar wire to a controller to the batteries.
I have a 20w panel to a controller to that small exit sign battery just for the brakes (it was there before the conversion, so I decided good to keep it in case I remove camper batteries for some reason).
Breaker box has Gen/City power select and breakers for Air Con, outlets, converter and spare.
Fused DC block.
Alternator goes through a DC breaker (100 amps) so I can choose to turn it off on a sunny day. I will add another breaker between battery and converter soon.
I think, since the converter does not send power to the battery, that I can just use a fused circuit and send power to battery if I want to charge it that way. I do not think this would cause any issues. This will connect the converter power to the battery, as is the converter only powers the camper as mentioned above post.
That's no biggie, but when I switch back to battery there will be power going to the converter switch (switched to BATT) and power going out to fuse block which would be connected to the battery, or the battery connected to it sending power to the switch too. I think, electrically, either is the same - just power going from batt to the switch… Or am I missing something critical?
