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

This is a well-engineered controller. Ive had no problems with the BlueTooth and the TTL serial output port is great if you wish to connect to a microcontroller, etc. Would buy again (& did buy an AC/DC Victron charger, too). Loss of 1star: Today learned it is a bit quick to shutoff the load output. Testing using a no-load-connected 750W DC-AC inverter (it draws 6W at 12VDC after power-on). If I connect using thin wire 20ga, it works fine, but if I attach the inverter using short length of 10ga wire, the high inrush current and voltage drop on the Victrons Load+ terminal causes the Victron to disconnect the load from battery. Reading their (good) online forum it seems to have issues with some DC refrigerators or halogen lamps, lights where resistance is low at turn-on & there is a high inrush current. Would be nice if it could handle a bit longer inrush duration (seems to occur in <200microseconds). Solution would be for users to wire such high-inrush loads to the battery directly, but that takes away the ability to monitor load current. Victron also has a bunch of other solutions to monitor system current, so one could use one of those, at additional $ and complexity.

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 own many Victron charge controllers. I like these the best because: 1) They actually work with most battery banks -- 12/24/36/48, Yes 36v works. 2) Unlike the bigger more expensive units, the fuse is external and replaceable 3) You can buy 6 of these for the price of a 250/100 controller 4) If you have one big charge controller and it fails. Your whole system is dead. There is strength in numbers. Unless you NEED big high voltage strings, these are a better option in my humble opinion.

Ive had Epever and Renogy controllers which were both difficult to read and configure for Lithium battery. Once I resigned myself to bluetooth - I loved it! The software offers a lot of programmable options which is important for LifeP04 battery (check out Battle Born batteries for info on how to configure). The bad: Victron says to use 10AWG wires. Good luck. It took a half hour to install two cables. You install. You damage the wires. You cut. You reinstall and on and on...By the time I got both in, the terminal box was trashed and the screws (pleeeeease, my daughters Barbies jeep has sturdier screws..and theyre plastic) the screws have a very shallow indentation for a flathead screw driver. After multiple attempts of tightening, one of them was stripped. Ive ordered a 100/30 in the hopes of actually being able to use 10AWG. (Victron says that model accommodates 6AWG but reviewers disagree......) Disappointed but hopeful. If you are going to use this, go with 12AWG.

Works better than I expected to it does exactly what it says and it works perfect for a battle born battery no problems with it very happy purchase Having built-in Bluetooth helps a lot if you dont have to buy the extra dongle for communication I really like the fact that its customizable you can set the parameters that you would like for your setup which is extremely helpful For whatever reason it seems to produce a little bit more voltage and current then I would expect it to thats probably what its designed to do but its a major Plus to me

The Victron 100/20amp controller installed and started without problems. I was able to use the VictronConnect app to look at the status of the system and configure the charging profile for my 100 ah hybrid gel battery. The controller powers all loads until PV capacity is exceeded then adds in battery power as needed. No need to remove battery for charging ever.

I have this on a small pico hydro unit and it works well. the app is nice, its easy to use. 4 stars, not 5 because the bluetooth connection, while good, limits the usefulness of the app, would be better on wifi, and because its somewhat limiting in what you can do with it, and limited configuration without buying a bunch of other victron equipment, but if all you need is a plug and play small controller, this one is nice, its super small, looks good, and works well.

I have three Victron Energy solar charge controllers of different sizes. I love them all and personally think they are the best. They perform flawlessly and are extremely efficient. The controllers all have the same configuration interface per Bluetooth with the Victron Energy App on iPhone/Android. I can set up fully customized charging profiles easily and can see the performance at a glance. The controller is small and robust, weather proof and is a great value for its performance and price. I will say that if you attempt to get any support from Victron Energy, forget it. You are out of luck and have to go to the dealers for help. Please check who the dealer is before you buy so you have someplace to turn to for support if needed. Because of the support aspect, I give this controller 4 stars. I wish there was a better support system for customers.

I highly recommend this product. Just returned from a 63 day camping trip during which the Victron 20 Amp controller worked flawlessly. 60 of our 63 day trip were without shore power and relied on our 100 watt solar panel. While I have a generator, there was never a need to use it to charge our batteries. The Victron controller was part of an upgrade I did that replaced a cheap PWM controller, moved the controller from the solar panel to the battery box, and added 8 gauge wires from the controller to the batteries. The Victron controller charged my two group 27/66 amp hour batteries more quickly and more deeply than the PWM controller. My energy into the batteries from my solar panel now always exceeds my energy out (I track cumulative watt/hours). I could also run my fantastic fan during the day and my batteries would still receive an excellent charge. These MPPT controllers charger more rapidly than PWM by converting excess volts to additional amps. The Victron controller consistently stepped up the amps coming from the solar panel by as much as .7 amps. Excellent product!

This is a good solar charge controller, once you setup the battery parameters correctly it works really good, it is efficient. What may makes it difficult for some people is the fact that you need the specs from your battery manufacturer to know the battery charge voltages to setup absorption, float, and equalization (only for Flooded or if your battery manufacturer requires that) You need a special usb cable if you plan to use the app in a laptop running windows, unfortunately the bluetooth connection doesnt work for that they say on the Victron forums that they are working on it. The bluetooth app is good, I allow me more distance for monitoring my batteries with more independence, instead of looking to the tiny LCD screen of my old and trusty PWM SCC. UPDATE: this controller have the tendency to consume the battery no matter the chemistry you have. Same thing happens with SLA or LiFePO4 you have the battery all the way to the top and then the controller takes from 12 to 20 amps per day. I have disabled the load, it is permanently off but if you use a voltmeter it shows that you have 0.6 volts on that and 0.1 volts if I disconnect the solar panels. I suppose it is a design defect, but who knows. I will be moving on to a different product this time because at the rate it discharge a battery you are wasting precious solar energy and there are cloudy days that wont allow the battery to be fully charged.
