Maineah Posted July 2, 2018 Share Posted July 2, 2018 PM motors can't be beat very efficient. My 100 watt setup will run the fan on low and still charge the battery. Quote Link to comment Share on other sites More sharing options...
WME Posted July 2, 2018 Author Share Posted July 2, 2018 Its just a basic, simple setup. 280w, 24v single panel. Its was discontinued and sale priced. The replacement panels are 300w. My RV has a fiberglass roof so I used one of these mounting kit....https://www.ebay.com/itm/ECO-Whole-Set-Solar-Panel-Mounting-Bracket-RV-Caravan-Boat-Corner-Bracket-ABS/232241948536?hash=item3612b2e778%3Am%3AmzY08QvQ5f-7sUoReXQxQgA&var=531463143353. They are glued to the roof with 3M forever boat glue. My roof has a curve to it so I had to massage the brackets a bit. The cables are Dicored to the roof and are run down the refer roof vent. 4 ga wire from the panel to the MPPT controller, 1 ga from the controller to the batteries, the converter also has 1 ga wire to the battery. The controller, converter and the 2 coach batteries are all within 2 ft of each other. Its about a total 20ft run for solar panel cables Quote Link to comment Share on other sites More sharing options...
