Rogue 3024 MPT vs Xantrex C35
For the last few years I have had a Rogue 3024 MPT controller installed. It wasn't my original controller. My original was a Xantrex C35. While the Xantrex was installed I was very disappointed with my production. I felt I was only getting half of what I should be getting from my panels according to my Trimetric. After I installed the Rogue, my production went up some but not what I was expecting. I later discovered that part of my load was bypassing the Trimetric shunt because the generator ground was wired directly to the batteries and the generator was also grounded to the frame. I lifted the generator negative cable to the batteries and suddenly all was well with my measured solar production.
I always wondered how the Xantrex was truly performing compared to the Rogue. I never got a chance to make a comparison until now. I am selling the camper so I removed the Rogue to use on the new camper. I re-installed the Xantrex. I had previously posted here the Rogue performance but it must have been archived as I cannot find it. I do know that it would put out up to 29 amps at high sun on summer solstice. Well yesterday and today I checked the output of the Xantrex at high sun, no clouds and the most I saw from it was 23 amps but was usually around 22 amps. I was pulling the batteries down by putting a 600 watt load on the inverter while checking the controller current to the batteries. I had the converter turned off.
I am convinced beyond the shadow of a doubt that MPPT is worth it for me as far as these two controllers go. The difference is over half of the output of one panel. I have 3 ea 135 watt Kyocera panels.
