RE: Follow up Solar Question

Besides the controller's spec for connection sequence for whatever reason to do with that controller, any "12/24" controller wants you to connect to the battery first so it can "see" whether your system is 12v or 24v before it is connected to the array Yep! I learned this the hard way. I did it backwards and the controller was reading for 24v. I thought I had torn it up right off the bat.

Katdaddy, Permanently connect the charge controller to the battery bank with a fuse close to the battery. The rest is unnecessary at 130 watts. I've read some conflicting information on that. What size fuse should I use.

RE: Follow up Solar Question

Some controllers don't mind and others do (eg Morningstar minds) when you disconnect from battery you are supposed to disconnect the panel from the controller first. You can't do that with the controller on the back of the panel, so it must be one of those that does not mind. The new controller might mind, don't know. In case it does, you should have a switch in the panel to controller wiring so you can do it all in the right sequence. I am also installing an SAE plug to bring the solar into the camper.

RE: Follow up Solar Question

Thanks for the replies. I have purchased a Rich Solar MPPT charge controller and plan to mount it close to the batteries. I was wondering if all of the recommended disconnects and fuses or breakers were really needed, as I have none with the current setup and it worked just fine.

Follow up Solar Question

I bought a 130 watt solar suitcase lase year for our trips to the mountains, where we have no hookups. It came with a cheap PWM charge controller and alligator clips to connect to the batteries. Used it on our Fall trip and it worked great. On a previous question someone recommended upgrading to a better charge controller and mounting it inside the camper, which I am in the process of doing. In researching the install I have watched countless how to videos. With the suitcase as it stands I just hook the alligator clips to the battery and go. All of the how to videos say I need breakers and shut off switches and fuses. So, what is different between the two? I don't have a lot of space in my battery compartment to mount all of the devices that I see recommended. What do I really NEED? As always all help appreciated.
