Intelligent 10A MPPT Solar Charge Controller, 10 Amp 12 Volt Solar Panel Regulator with Digital LCD Display + Temp Sensor + 2 Set Quick Connectors for AGM, Gel, Flooded, Lead-Acid, Lithium Battery

I would have liked to write a more lengthy review but that's not possible because this MPPT simply did not work. I even put a meter across it - nothing, zilch, nada. Returned for refund today.

Outstanding build quality. Simple to use. Wish the display provided a little more information (watts and resettable watt-hours would be nice), but any display at all is hugely appreciated.Converted mine to the much more useful powerpole connectors.Tested with a power supply and it held 14.2V (battery) at 10.4A for 20 minutes and just warm to the touch. Held the same charge current sweeping from 15V - 25V. Been cloudy for days here, but I'm sure it'll perform well with an actual solar panel in the sun; I'll update this review when I've put it through its paces.One thing to note is that the display only fires up once it's detected Vsolar > Vbatt. So, don't plug in just the battery, see a blank screen, and think it's dead!

Other than having reverse polarity compared to all my other stuff (get the polarity reverser). I use it to charge an 12V SLA battery for a trolling motor on a dinghy from a 100W panel. The use cases are limited at 10A max output, but a very handy solution in some use scenarios like the one I mentioned. Just remember that if/when the polarity is reversed compared to yours and you use the reverser, also the output is reversed. Would definitely get this one instead of a cheaper PWM controller (trust me they get annoying and require babysitting). Would probably give 5 stars without the polarity hassle and if it would be a little bit more inexpensive.

I have a Suner 80W panel for keeping my tractor charged. Using the Suner supplied controller, while it worked, I was getting a feeling it was also draining the battery at night. As well it was a PWM (60% or so efficient) design and not like the Allto MPPT (85%+ efficient).The Suner is a charger designed for a 'solar solution' and not for charging batteries. So connecting was a PITA (disconnect from the battery, disconnect from the panel, reconnect to the battery then reconnect to the panel). Not Suners fault. Just their system is not for simply charging a battery (it is a 24V or 12V and it figures out the correct voltage during the connection process). It is designed to be connected and left connected.The Allto is a battery charger. It is MPPT. You plug it in, and if the panel has sun, the charger lights up and reads output. You connect the battery and it reads the output amps and battery state of charge. Nice. No special unplugging/plugging of everything.While I did not test this feature, it is supposed to have polarity protection. Instead of 'seeing what will happen', I checked the polarity. I also wrote them before I got the unit and asked (they responded within 24 hours and sent a manual as a pdf). The specifically mentioned the Suner panel was reversed polarity so I got some polarity reversers and installed one on the panel output. So, confident I had the polarity right, I plugged it in and Done! I did put a little dielectric grease on the plugs as I wanted to avoid corrosion issues down the road.This is 'day one' and if anything changes, I'll update. But, at the moment, I feel good about this product.
