MORNINGSTAR SS-MPPT-15L SunSaver MPPT 15 Amp 12/24 Volt PWM Solar Controller - 1 item(s)

Easy to install. . Used to control battery charging via a 200 watt solar panel

This is a great, reliable MPPT charger. However its expensive and doesn't detect end of charge. Charge termination is purely timer based which means that your batteries may not ever be fully charged or they may get over charged. There are other feature rich and better priced MPPT chargers on the market from reputable manufacturers. Do your research before buying.

I run two solar panels in parallel and my three year old Xantrex controller gave up the ghost while on a two month cruise. A good local supplier firmly recommended this Controller as a 30% more efficent ( better electronics/ alogarithm) controller. I cant measure or comment on the efficiency part but it is much more compact, easy to mount and install and works will. I like the fact that it gives me a visual idea of the state of charge of my batteries with three LEDS . My Prime membership gave me free delivery in less than 48 hours from South Dakota to the Florida Keys - that was impressive- and I was repaired and on my way !!

High Product quality. Shipping faster than expected!! Very valuable

Had to install the controller in an area where I can't reach easily so with it I also purchased the RM-1 display. The reason I chose this MPPT was because of the remote meter. After installing both (which was a real pain in the donkey) I discovered that the solar amperage cannot be displayed with this MPPT (only with the SunSaver duo). Had to dismental and returne. What a bummer!!! shame on you Morningstar for not disclosing that to potential buyers!!!
