DuoRacer 2210N-DDS 20 Amp MPPT Dual Output Solar Controller

Great product

I installed my first solar panel--a flexible, 11 watt job--on my 30' sailboat in 1996 or thereabouts. Paid about $170 for it. The controller I used was a small brick-like device with blinky lights that cost another $75. That combo kept many an idle battery topped off for over 20 years. Two years ago, I finally upgraded to a 30W panel and inexpensive PWM controller. The panel was great but the PWM controller was worth exactly what I paid for it. Enter Custom Marine Products and the DuoRacer 2210N-DDS. CMP's Web site is fabulous, and their service was fast and efficient, despite the pandemic. The 2210N is built like a tank, and the wide array of information displayed by the DDS version ensures I know exactly what's going on inside the system anytime I choose to look. Way better than blinky lights (or icons). The dual output is a bonus I didn't know I needed. Definitely a 5-star experience.
