I pulled my trailer out of the garage to give it a good cleaning. While I had it out I fixed an issue where I was getting intermittent connectivity between my solar panel and charge controller. Turns out I had not seated the Anderson power plugs completely in the housings and it was allowing the feeds to separate.
I was checking the controller to make sure it was working well after fixing the connection and and this is the result. I use a 190 watt 36V PV panel into a MPPT charge controller.
Conditions: partly cloudy around 10:30 am with the trailer facing due south. Battery mostly charged. The Fantastic fan had been running for about 15 minutes before getting the charge controller hooked back up.
1) At absorption charge rate the controller was putting out 7.6 AMPS or 101 Watts at 13.4 Volts with the Fantastic fan going. This gives me almost 80 watts of additional capacity to charge a drained battery. The Absorption charge dropped to maintenance mode in less than 10 minutes. By no means was I approaching the maximum capacity of the panel and charge controller.
2) Even when a cloud passed by and blocked the sun I was still getting almost 2 amps out of the controller in full shade. Still enough to charge the battery if all the loads are turned off.
3) The LED lights I installed pull 0.3 amps for the cubby's and 0.6 amps for the main light. Guess I will use the cubby lights most of the time and only use the main light when I need to get into the rear cabinets.
Overall very happy with the set up and how it is performing.
