Eco-Worthy MPPT and Solar30 PWM Test
Did a quick backyard test of my two solar controllers using the actual trailer wiring etc as intended for camping with solar later this month. Got some blue sky, no clouds. The Eco-W on the 230w p...

My limited, in general observation is that somehow, a PWM controller, in the 10-15 amp ratings, somehow loses about .3 Amp from straight off the panel, to straight off the back of the controlled side of the charge controller. I don't know enough about it, but I've seen it on a 10 amp, 20 amp, and the same 30 amp unit that you have, and I chalk it up to some sort of parasitic circuitry loss inside the PWM charge controller.
This is on my 120 watt portable folding solar panel I picked up from Solar Blvd.
Just an observation, make of it what you will.
Nope. You have wiring or connection "issues." I can take panel Isc with my multimeter, hook back up, and see the same amps on my Trimetric going into the battery. Same with my previous ASC and LandStar controllers. Also with panel-direct, by passing the controller.
If you can't, that is a signal to go trouble-shooting amongst the set-up.
