Morningstar Corporation Sunsaver TrackStar 15 Amp MPPT Charge Controller 12V/24V

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

Absolutely the best small charge controller ever, pricey but worth every penny.Programming is not straightforward, but if you are using AGM, Gel, lead,.. you don't need to do anything other that set toggles.I will never understand how the cheap ones will last long. This is a high quality controller.Running dual 300W 36V 9A (in parallel) to 24V Li-Ion pack, no BMS, early morning bulk is important for me, so i dont care about waste during day..

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 !!

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.

Am using it for my Solar system for Ham Radio. Has significant radio hash. Would have had a different brand but the other folks stop making them. Works as advertised and does a fine job regulating 24V 100amp solar panels into a 100 A/H AGM battery. Yes, kind of spendy but does the job. Hope it lasts longer than 5 years.
