Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth)

Perfect for our RV solar setup.

I am going to mount this Victron 75/10 Solar Charge Controller on the firewall of my boat. I have a 50 watt solar panel I will be using to keep my battery topped off while in storage. The app was easy to download and after 2 minutes it was done updating itself. The charge controller only took a few minutes to install. In my testing of this solar charge controller over the last two weeks, it has worked better then expected. I am very happy with it and will only be buying Victron in the future. I am using the streetlight function and the load connection to run a 10 watt led light bulb while the boat is in storage. I keep the boat on the side of my house and there is no light there. Now, using the boats battery, the light comes on at night and goes off at sunrise. It only drains the battery a little during the night. Then, the next day, the solar panel charges the battery up to full and maintains it in float mode perfectly. By the way, Im using the QILIPSU Hinged Cover Junction Box, - 150 x 150 x 90mm/5.9 x 5.9 x 3.5(L*W*H) size box. The box seems like it was custom built to fit my Victron 75/10 Solar Charge Controller. It is watertight, made of thick plastic and has stainless steel clasps. Price was very good for the quality.

I purchased this charge controller to see if it would bring in more power than the one I was currently using which was the Tristar 45 PWM controller. There is a lot of mixed information out there about whether MPPT actually makes much difference or not. Some say that they increase power by as much as 30 percent and some say that this only rarely happens. Because of the mixed information, I put off buying an MPPT controller for a couple years. I have now had this controller through a summer, fall, and winter in Colorado. The Tristar PWM controller that I was using would typically peak at about 350 watts of power input and this would drop considerably during the winter months. After installing the Victron MPPT controller, the peak watts moved up to about 450 watts which is a 28% increase in power output. More importantly, during the colder winter months (its now January 2019), the Victron MPPT increased its peak power output even more with peak input watts of 500 or more getting to the battery. Sometimes I have seen it as high as 600 watts. The reason for this increase during winter is that as solar panels heat up their voltage drops. As they cool down the voltage goes up. So during winter, when the panels are cold the voltage goes up a lot and the Victron MPPT charge controller can turn that extra voltage into battery power where PWM controllers can not. As a result, with the Victron MPPT controller, my power in summer and winter are nearly identical. During summer the charge hours are longer but the input is lower. During winter the charge hours are short but the cold solar panels voltage is way up and put out more power than they do in summer. I highly recommend this charge controller to everyone but for people in colder climates this type of chage controller is a must have. My system is 6 Renogy 100 watt monocrystaline solar panels hooked at at 24 volts to the Victron charge controller which is hooked up to a 12 volt LifePo4 battery system.

After using it, I am extremely impressed. If I can give 5+1 stars, this is the item that gets it because of the ease of use and mostly because of the results. With a typical good 12v PWM controller without tilting toward the sun, I get around 38w from a 100w solar panel (12v 3.1a). With this MPPT, I get an immedately 50% increase. YES 50% increase in solar power to 58w!!! (19v 3.1a). If the solar panel is tilted toward the sun, I get 75w (19v 3.9a) which is close to the best solar efficiency for my 100w solar panel. It kept all the voltage that the PWN controller would lose and maximized my wattage gain by a significant range. Even when under cloudy days, it still generates more wattage than a 12v PWM. I HIGHLY recommend anyone who is planning / upgrading their own solar panel system to get this or any one of their MPPT controller. The wattage gain is so significant that youll get your money worth much sooner that youll expect. This is excluding the potential ability to upgrade of your solar system in series and in parallel compare to a 12v PWM which can at most only be connected in parallel. In short, GET IT for your solar panel system.

Does a great job regulating the battery power on our RV’s solar setup.

Used to replace a pwm controller on my 100w portable system. HUGE improvement on efficiency for my rv charging.

I have three Victron controllers and I love them. Glad I went with Victron. The three I have are the SmartSolar type with Bluetooth. The controllers communicate and I can monitor all of them through their phone app.

good little controller. The terminals are very flimsy & cant get 8 awg or even 10awg wire in without stripping cable stains down! Connection problems they come loose or fall out. It wont charge of they are loose! They are to close together & might short out… make sure u use strain reliefs & zipties. After tgat i was able to get it to work…Manual to small to read & obtuse! No customer support ur on your own here!

Great charge controller, but the shipping packaging was awful. Product box was destroyed and a corner of the product has a scratch. Product was only placed in a plastic mailing bag with nothing else for shipment.

Being this is my set up i struggled with set up. Once i got it connected and running the app is very user friendly and very much worth the extra money to invest in victron. I bought the 100/30 smart charger. Configuration was simple just sitting in the recliner lol!! Can easily monitor progress with 2 flicks of the thumb!! Only thing is read the book and except the location permission. YES HIGHLY RECOMMEND!!!
