? about adding a battery charger ?

[TimC]

I have a NOCO G7200 battery charger that I use for multiple purposes and have never used in my camper. I'm taking a couple trips to RV campgrounds with power. This weekend's trip is expected to be cloudy and rain. If I want to add the harness with ring terminal connections it came with to my 12v system in my camper would it be OK to connect the (-) ring terminal to the negative buss bar and the (+) terminal to the hot side of my main kill switch? Any reason to connect directly to the battery posts?

I have a complete solar charging system with 144aHr, 12v battery bank and use only 12v appliances. The buss bar is less than two feet from the battery bank and the kill switch is about the same.

I noticed that the Vistibule trailers had a NOCO G7200 as the main charging source for their battery.



Thanks,
Tim

Should be fine. Is there any switch, fuse or breaker between those points, and your battery? I have the same harness, but it's on the battery terminals. I only did that way so I didn't have to rework other terminals.

None of the above... I don't yet have a fuse on my battery wiring. Neither from the solar charge controller or battery to fuse block. I'll be remedying that when I wire in the NOCO. It's currently 12 awg from battery to fuse panel and the same from charge controller to battery. I'll protect those runs with 20a fuses inline. I'm also updating with two Bayite ammeters to monitor solar production and my consumption.

Thanks for the help...

I am working on my son's teardrop and have a related question to the original post. Specifically I want to know if it is OK to wire a NOCO Genius 5a charger output to a terminal block that includes my solar output (after charge controller). I'll be adding a fuse just after the battery, before the fuse panel. The reason for the term block is the battery bank will be a distance from the charge controller and the NOCO charger. Term block does not show the jumpers. Drawing below...

Yes its perfectly fine to take multiple charge sources to the buss bar.

That's essentially what we do. Our charger is built into a PD 4045, but we can charge from that, or a solar panel via a charge controller, or the tow vehicle. The wiring for the first two is the same as you show. Of course, I don't anticipate more than a single charge source at any given time.

Thanks Scott and Tom. In his teardrop the solar will be disconnected from the system when charging with 120v.

I appreciate the advice.

That’s exactly how I have my NOCO charger wired.

If you have a spare fuse on the fuse block you can also run the solar there. and then when you kill the 12 volt switch it will disconnect it from the battery.

Would you need a switch to turn off the PV panels to the terminal block when you are running shore power? Otherwise, if you are plugged into shore power, then the sun comes up and you have both systems feeding in power. Or is that a problem?

Your solar charge controller and battery charger will not fight against each other or interfere with the other. When the battery gets close to full the charge will decrease as normal and it will be fine.

OK, thank you! Trying to keep it as simple as possible!
