I Don't regret it and glad I got a PWM. I went with the Bogart Engineering SC2030 paired to the Trimetric and four 130 watt panels charging four gc2. I recently helped a friend rewire his rig. He has a Blue Sky 3024 mppt with remote monitor and 470 watts and 3 agm 12 volts. I can be down 80 or 90 ah and he 50 and we are charged at about the same time. I have 50 more watts and he has mppt. As I understand it I dont believe he's getting the full benefit of mppt because his 3 panel voltages vary by almost .9 volts. They were added one at a time as his system grew.
The Trimetric is an excellent product and there are a lot of good posts on the SC2030.
For parallel panels the voltage should be very close for either controller and the amps very close for serial panels (usually MPPT).
