It's nice, I like the fact u can charge two batteries at the same time and choose which one gets the most power. Would have been nice to get this in a MPPT controller at 30amps. But that's fine, I'm Running this in my small fishing boat it's my tendering/charging system. I wanted to help the trolling motor battery the most, and the crank battery the least, so I have it set 90/10. My first time with solar so just playing around here. Two new batteries one a very large 75lb deep cycle marine the other a AGM blue top marine crank/deep cycle. It comes with a nice view meter for viewing the voltage mainly nice to see what's going on at all times while charging or while the batteries are hard it work out on the lake. You will have to installing "3" 30amp inline fuse! One on each battery and one close to the solar panel. It's possible to use the solar inline glass fuses they make for 8g wiring. And While being water proof. I shopped all over my town until I found a very large in line fuse made with with 8g wire. So go find and buy 3 of the glass inline mc4 style fuses and install them before u setup. And another thing, I hope u have plenty of solar panels or willing to wait on changing time because 2, 12v batteries will take a while to charge on just one,100watt panel. Your only going to get more of a tender if your not in full sun all day. U need the Maximum 10-15amp requirement for charging. And a Min of 2amps when tendering. So make sure u have plenty of sun hitting your panels all day or enough panels to get your max and min requirements. Or u may end up killing your batteries over time, as deep cycle batteries need to be topped off soon rather then later. All in all I really like this setup it really tops my batteries off to there MAX!! Without hurting them, which gives u more run time.PS: If I had to do it all over again I would , but I'd like to have a MPPT controller also. It blows my mind how much power your losing from your panel to your controller to your battery to your device or if your using inverter your losing a lot more. Quick math for u. 100watt panel your only getting about 80watts then take away about 30 more watts using this controller. So u roughly have a 50watt panel pretty much after all said and done. Then if your not staying in full sun all day.? Your not even getting much. Your just pissing in the wind total waste of your hard earned money. And when your using/running a inverter then it loses a ton of power that's about 30watts or more!! U end up with a 40-50watt panel for sure if your in the blistering hot sun.In a world where overpromise and underdeliver seems to be the corporate standard, it is refreshing to find a product that does what it says, and does it well. I've been using this for for over a year now, with a couple different configurations on my solar array, and it has performed with no problems, no mysterious readings changing. I have not needed to 'turn it off and back on again' to get it to work. It just does its thing and charges both of my battery banks.The only complaint I have, and it is not a strong enough complaint to take a star away, is that the advertised ability to adjust the settings does not really exist. In order to fine-tune it (i.e., lets say I wanted to adjust the max output by a couple tenths of a volt) you have to buy a $40 meterbus adapter. What's more, that adapter is RS232--while that was a common I/O port 20 years ago, good luck finding a computer with that interface these days. That said, it works fine for my needs out of the box and probably works for all but maybe one in a hundred customers who might actually need to tweak the default settings.I have used SunSaver products for twenty years on small scale year-round solar camps, on solar panels mounted top of my truck, and elsewhere. They are solid products. And their PWM charging methods regenerate older "winter worn" / "generator worn" batteries when the days get longer in spring and there is enough sunlight to attain deep charge again. Well worth the price!Forget those cheap little plastic LCD screen things, I found those cheapies don't last but a few years at most, and don't do the float charge properly, so boil off the sulfuric acid solution, markedly shortening battery life and causing corrosion in your battery box. What you spend on a good charger will save you several times that on battery costs! Cheapies are cheap because they are Crap. SunSaver products WORK!Do note that with the mode switches, this product needs to be kept dry. There are other SunSaver products which I have used that can be exposed to condensation and even rain runoff with no damage other than some corrosion and electrolysis of the terminals. (One of my newbe mistakes in 2002. That charger survived outside for seven years, before the Summit Fire in the Santa Cruz Mountains wiped out everything where I was living.) For best results, read up on how to treat your batteries, as they are the weakest link and shortest life components in any solar system. SunSaver products markedly extended my battery life! Well worth the price!Assolutamente insoddisfatto. Non ho ricevuto la merce in oggetto. E non ho notizie sulla tracci abilità. È inutile che mi si dica contatti il venditore . Inammissibile lo scarica barili di Amazon. Quando è Lei che deve farsi carico del problema. Io dovrei rinunciare a partire per riposo per aspettare la merce??comunque è 0 la mia valutazione.Exact match to one the temperature sensor failed on. Easy replacement. Even arrived early.
