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

Ive been using this charge controller for over 2.5 years now. This is the best MPPT charge controller I have used. The bluetooth feature is great though it is pretty short range. The app is nice, easy to use, and keeps track of the power generation data and charge state of the batteries. It keeps a 30 day log of things like max daily PV power output, time spent in bulk, absorption, and floating charge modes, and how much energy was generated each day and a lifetime total. To date my small 600w system has generated over 1.5 megawatts of solar energy. A big plus and one of the main reasons I got this unit is that it is passively cooled by fins on the back. No moving parts and no loud fan. Installation was a breeze and I like that you can add more of these in parallel to increase your power generation if needed.

Not much to say. It works as advertised is is very high quality. Well worth the money. I will be buying more Victron products.

Should have bought this from the get go.... It just works perfectly, app is super easy to use and there is a ton of information it gives you

Worked for a few days and I disconnected it to try a different solar panel and now VictronConnect can’t find my 100/30 at all. Tried all the suggestions on Victron’s site but still no luck. I’m going to try the Bluetooth dongle. If that doesn’t work then I give up and buy another brand. Update: The Bluetooth dongle worked. The 100/30 can now be seen as a devise in VictronConnect. I am upgrading my stars, but because of the extra cost for the dongle, I’m only adding two. I needed the Bluetooth to work in order to configure the charge controller correctly for lithium batteries. Update: An amazing thing has happened. After the 100/30 Bluetooth quit working, I contacted Victron and asked how to apply for warranty service. I was told to go thru Amazon, where I purchased it. Not really expecting much, I was very happy to receive a totally new 100/30 yesterday, 9/16/20. I have now installed it and it works perfectly. This changes everything! I’ve never had such excellent warranty response. Thanks very much. This earns full stars as well.

After purchasing a 26$ controller, which seemed to work okay, I decided to upgrade to a bit more professional controller for my simple solar solution so I could have a better view of what was really happening with my 400 watts of solar panels dumping to 2 marine deep cycle batteries. This unit is everything that I expected and much more. The bluetooth interface is amazing. 26$ will get you a charge controller and most likely it will work but with the bluetooth interface (iPhone, IPad, and Mac) on the Victron, I can watch this one work real time along with built in trending. It keeps track of my power generation daily with bar graphs showing peak Watts and Volts per day along with battery charge max and min. I can see, while writing this, I am currently making 301 watts and have been generating for 3h 43m in bulk mode loading the batteries. For me, that is worth the extra money and 5 stars for Victron for making a product that is easy to use and very stable. NOTE: Make sure you size it right. Many different models to chose from to fit your solar size.

This is my second one of these. The Bluetooth based information from the unit raised my solar expertise up a level. Do make sure to change the Bluetooth pin as this is an internet of things device. Voltage does change curiously, but that’s the built in temperature adjustment. The load circuit does get tripped occasionally, I presume from some of the cheaper power outlets I used. It isn’t clear how to reset when this happens, I just disconnect the positive load and connect it directly to the battery, then switch back after a awhile. I’ve had that happen 2-3 times a year on my first unit and it is still working good. This is a lead acid designed controller but is fully programmable and includes agm and lithium presets.

Solid quality.

The SmartSolar MPPT 100/50 Charge Controller Bluetooth worked initially, but it suddenly will not work. My other Victron Bluetooth products have worked for a long time, several years. This did not. It was a good charge controller for a few months, but now I have no control over it. I went through all the troubleshooting guides, and performed everything they suggested, but still will not work. I am considering either getting the optional display or the Bluetooth Dongle, but it is not necessary for Smart Solar products, and if the cost for the two are 25% what a new solar MPPT charge controller from a competitor costs, I will probably just change it out for a different brand. Too bad - all my other Victron products in the system work well. The Bluetooth on other components work fine. Since I cannot connect to Blue tooth, I cannot even update the firmware to see if that works. There is really no real tech support that I can find.

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

Spend a few dollars extra and get the best. In my case the small size and feature set made it the only logical choice for my boat. The bluetooth connection feature(s) via smart phone is worth every penny, you can change LifoPO4 to lead acid settings in 30 seconds. I can monitor my battery bank from the house, If you are going to hook up 3 or more panels in series you may want to get the 100V version for about $20 more. Cons: I have read these units run a little warm. That is because they have the best MPPT controllers in the business and actually do create the most watts from the array, Bluetooth network probably sucks some power to maintain, but we are talking minimal amounts. The screw connecters for the wires are small, and I couldnt put a #10 stranded marine wire in them. Customer support is funky, but the distributor that sold it to me called me on phone within an hour. Documentation can be confusing at times
