Solar Kit
Just received my kit. 2 100w panels with a 30a pwm controller. Hoping it will recharge my 2 GC2's. I am alone in the trailer and power use is min. Any thoughts?

Your connection sequence is batteries to controller then array to controller. So you don't want to disconnect from batts with the array still on the controller. Covering the panel would be a good way to switch off solar. I put a switch on one of the wires from the panel close to the controller but my controller is easy to get at for that.
Useful if you are disconnecting the batteries for various reasons, you can turn off the solar first on the array side. Also with the array wire "open" you can measure Isc and Voc if you like.
Thanks for the instructions. Would it fry the controller if the sequence were reversed? I hooked it up in that fashion as the instructions said, batt first then panels. Just curious.
Maybe fry it. Might depend if it has a load on its load terminals but then no battery as well. They all want the batteries connected first to let the controller decide if it is going to be 12v or 24v battery before the array is connected. Since some controllers don't want array and no battery, IMO play it safe with yours if there is nothing mentioned about that in its manual.
