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

So far working fine on my 480 watt 48 volt panel

I really like Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth). It really is doing everything for me. AAAAA+++++

Replaced a non working controller in a RV.

The terminals where the wires connect are tiny. My solar panels use 10 gauge wire which never in a million years would fit in the tiny connectors. The manual indicates that 10 gauge will work but I had to remove about half of the strands to get the wire in. I then bought some crimp on ferrules thinking that the 10 gauge ones would fit. Nope the 12 gauge tips barely worked. I hope that these tiny wires are enough for the power from the panels and into the inverter...

Charge controller did not work properly from the beginning. Ultimately ended up with error code 28 repeatedly and controller was dead. I returned it and the replacement is working correctly so far.

Victron are the standard in solar charge controllers. This controller is well built. It has been in my campervan for almost 3 years now, and has performed flawlessly. The integral bluetooth allows you to configure the controller, and check the state of charging, all from your phone - no need for displays taking up wall space in an RV! I mounted this under the sofa in my campervan. If it wasnt for the solar panels on the roof, you wouldnt know I had a solar installation. It is very unobtrusive.

Seems to work fine. I have the SmartSense battery monitor which this uses to get accurate battery voltage and that is really helpful since I have a ~20 wire run from my solar controller to my battery. But having now owned 4 different charge controllers in the last 7-8 years, I dont think Victron is worth the extra $. Heres why: First, you get zero support. Thats right, Victron will only provide support to certified resellers, so if you have a problem and you bought from Amazon guess what? Youre SOL. In my case I believe theres a bug in their charging algorithm, but I literally cannot talk to anyone at Victron directly. (That said their community support is great, but its not the same as actual technical support). Second, some of their really useful features (like being able to monitor charge voltage over time and graph it) only work if you disable screen lock and leave your bluetooth device (phone, typically) connected and running the app. Dont change apps because your graphs will reset. Why cant this run in the background? The unit does have daily stats but that doesnt help me when Im trying to understand why charging isnt cutting out as expected. My personal issue is that I have a LiFePO4 setup (which this device does support), but I want to cut off charging on my setup when the battery hits about 90%. The Victron has several settings to shorten the absorption times, all of which seem to work when I drain the battery and need to recharge it. However if the battery doesnt get drained one day and starts off full, the unit still goes into bulk mode for several hours and ends up topping off the battery. I assume this is a charging algorithm-related problem, but its disappointing behavior and defeats the reason I purchased the device.

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.

This product is amazing. There is excellent software development that can be used both on your phone AND your tablet IN LANDSCAPE ORIENTATION. It comes with Bluetooth built in so that youre not having to decided between using an on device display thats the equivalent of a calculator from 1995 or extra Bluetooth dongles for incredibly limited app software development that is only usable on your phone. It has many different presets and the voltage ranges for those are all within reasonable levels compatible with a huge spread of brands. I recently had to replace my battery because my old charge controller was only compatible with its brand of lifepo4 batteries as the voltages were all set at 14.4 including the float voltage. I couldnt have the old controller destroying the new replacement battery, and I had seen the name victron mentioned in forums but I never really looked into it, but I was pushed into the situation so I did my research and was incredibly impressed with the features included, the accessible exterbal 25A fuze, and most importantly the intelligent app design that is also compatible with tablet operating systems to be used as an actual intelligent dedicated display. After installing this with 3x100w mono panels my new battery was able to go through all charge stages to float without error, unlike my other old controller that constantly had overvoltage errors on the old and new battery. Incredibly that company updated the their app to remove several features such as charge limit and imposed restrictions to certain settings, so the charger was literally unusable with the new replacement and I was pushed into getting something else. Im glad I was, the app support and common sense compatibility is amazing. The size is incredible too, its not big at all. Victron should be the first name people think of when they start setting up a solar system. There is just no debate now that Ive been able to experience both firsthand, and Im not interested at all in a different company thats willing to burn out the other brands batteries so that you purchase their own. I dont like that at all. Get Victron, dont argue with yourself about it. Youll have a working system much less likely in need of being replaced in two years like I was. You dont need to figure out the hard way like I did that Victron is top shelf reputable quality. Ill definitely be getting more Victron products in the future.

Experimented with a few other charge controllers for our off grid RV. I think I am finally happy with this Victron 100/50 charge controller. My 400ah lifepo4 batteries were charged from 54% to 100% by noon on a sunny blue Arizona sky. My previous charge controllers usually got the batteries to 100% by 2-3 PM if I was lucky. Love the app!! I was able to enter my specific batteries parameters that were recommended by Powequeens manual. Also able to see the history of what my panels and charge controller did for the day/week/month/year. Im Happy!
