SmartSolar MPPT Solar Charge Controller 100V, 30A, 12/24V

I’ve been running a full Victron setup in my RV since 2021, including the MultiPlus inverter/charger, the SmartSolar 100/30 charge controller, the BMV-712 battery monitor, and the Digital MultiControl panel. After years of use across various climates and conditions, I can confidently say this system has been absolutely rock solid. Each component was easy to install and configure, and the integration between devices is seamless. The MultiPlus handles all of my AC needs flawlessly, switching between shore power, generator, and battery without a hiccup. The SmartSolar charge controller keeps my solar system optimized and running efficiently, even on cloudy days. The BMV-712 gives me precise battery monitoring at a glance, and the MultiControl panel makes managing the inverter simple from inside the RV. What I appreciate most is how this system has given me real freedom. I can boondock for days without stress, knowing exactly how my batteries are doing and trusting that the system will just work. It’s added reliability and convenience that truly changed how I RV. Highly recommend Victron to anyone serious about upgrading their mobile power setup. Worth every penny.

I think among MPPTs these are the best available charge controllers, and they work well in the Victron "ecosystem". I had several of these and all worked well with no issues. The bluetooth is very reliable and I never had any connection problem. It also participates in an inter-device network between the smart shunt and a Cerbo that I have. Not sure if it does anything, but ok. It works with any kind of batteries but specifically good for Lithium. Just size it right for your system, as they get bigger and pricier with more power. My current recommendation for a smaller DIY system is to get a 24/12 Volt one, it gives sufficient room for modification, unless you want to go for a 48V. The Voltage and Amps (the first and the second number in the model) should be sized for your panel configuration. For example, a 6x100V panels configured as 3 in series and then parallel may produce over 600W of power on a sunny day, with 60+V and close to 10A, something that a 100 /50 controller will handle easily, and it can be a 100/30 as well. I recommend these.

Update (2/12/23): Current inventory of VE products: (2) 100V/50A, (2) 100V/30A, (1) 100V/20A, (1) SmartShunt IP67 (newer), (1) SmartShunt (older), (1) BatterySense. Best feature is the VE.Smart networking feature, which allows the components to work together to optimize charging of the battery bank. Update (8/2/22): Ordered a 2nd unit. Working great! iPhone app has many great features. Summary: I have evaluated quite a few MPPT controllers for Vine, and while all were decent, the Victron Energy (VE) has high ratings, so I decided to purchase one for evaluation. My solar/PV system specs: 1000W of panels; 24-volt, 270Ah marine battery bank (Optima); Voltworks 2000W inverter. Using the system to reduce our electricity bill. This review is for the 100V/50A, which is the 2nd VE controller I've purchased. Observations: The first thing to notice is that this one, unlike most others, does not have a control panel (just three LEDs); which means you'll need a smart device to read the values. There are two basic VE offerings: this SmartSolar (built-in bluetooth), and BlueSolar (requires a BT dongle). Between the two, I went with the built-in BT (SmartSolar). One great feature of the VE system, is that it allows the MPPTs to communicate with each other via BT; which is a great feature for a larger system. Recommendations: One reason to choose the lower cost BlueSolar over the SmartSolar, is if you do not need the additional features that the BT brings; but for me, I didn't mind spending the extra $30-40 (per controller) to gain those features. Pros: Industrial quality & features; good application support (firmware updated upon first connect); security (bluetooth); good/efficient charging algorithm; good data and graphs. Cons: No built-in display (offset by the much better app and graphs). Conclusion: At $225, rating this 5-stars. Of all the MPPT controllers I have reviewed, Victron is the recommended brand.

I just hooked up a Victron SmartSolar Charge Controller MMPT 100/30 to my 12v solar panel system. I'm testing this unit and will use it to upgrade my system to 24 volts. The first thing I notice is the weight: Solid construction. The 100/30 can handle either a 12 volt or 24 volt system - it's rated at 440 watts for a 12v sys & 880 watts for a 24v system. In 12v battery mode you can use 12v panels in parallel or two 12v in series for 24v and then in parallel. In 24 volt mode the panels output must exceed the battery volts so... the first time it's used it sets itself to the battery voltage, after that you use the software to configure the voltage. I have the Victron App on my phone as i use the Smartshunt - 500A w/Bluetooth module. Once plugged in the SmartSolar charge controller shows up in the App and gives all the data you need to stay on top of things. The Victron wireports easily take the #10 AWG (30amp rated) wire ; which is the correct size for a 30 amp rated controller; AND has Big Fat Flathead Screws to clamp down on those wires. Compare that to a mid-price item like Renogy; their wireport just fits a #10 wire, and the screws are tiny phillips heads that are hard to get a bite on... or a WERCHTAY 60amp (sure) controller that can barely fit a 12AWG (20amp). Victron seems to have dropped their prices; I always thought they were way too expensive for me, but now for the price of an intermediate tier product you go Top Tier: The Smartsolar MMPT 100/30 is priced about the same as a Renogy product and already has Bluetooth; Renogy wants another $30 for a Bluetooth dongale. All in all a solid product with good data software: it supports iPad, and my Android phone. It has many support products.

Ships fast and EXACTLY as advertised. Easy to install. App and bluetooth were simple to navigate. Stats on the app are accurate. Works perfectly in my DIY solar power statoon.

Excellent. It's easy to tell what it's doing. It's very responsive on the lights feedback to solar panel input. The Bluetooth app (on the Android store) gives good history info. This device keeps daily history logs for something like 46 days iirc. I will probably hook up 600W (6 panels) to it and 2 high capacity LiFePO4s (24V). Have been using it to individually charge each one slowly to max using one panel.

Bought Victron mppt for my off grid solar system, no issues with this! Range is very far, premium and well worth it! Have a 800 watt array on this 100/30.

Item worked as it should have. I would purchase it again if needed,

Great as any good manufactured by VICTRON

Très bon contrôleur de charge fiable et facile à utiliser Le bluetooth est vraiment pratique pour suivre la production solaire directement sur le téléphone Fonctionne parfaitement dans mon installation je recommande

Ich nutze den Victron SmartSolar MPPT 100/30 in meinem 12 V-Solarsystem – und bin rundum begeistert. Das Gerät wirkt sehr hochwertig, ist sauber verarbeitet und lässt sich einfach anschließen. Die Bluetooth-Funktion ist ein echtes Highlight: Mit der kostenlosen VictronConnect-App sehe ich alle wichtigen Daten in Echtzeit (Spannung, Ladestrom, Batterie-Zustand etc.) und kann sogar Einstellungen anpassen. Die App läuft stabil und ist sehr benutzerfreundlich. Technisch ist der MPPT-Regler extrem effizient – auch bei bewölktem Himmel oder schwacher Sonne wird das Maximum aus den Solarpanels geholt. Ich habe den Eindruck, dass mein System deutlich schneller und besser lädt als vorher mit einem PWM-Regler. Die automatische 12/24V-Erkennung funktioniert einwandfrei, und auch unter höherer Belastung bleibt der Regler absolut stabil und zuverlässig. Fazit: Wer ein intelligentes, leistungsstarkes und langlebiges Ladegerät sucht, ist hier genau richtig. Top-Produkt – klare Kaufempfehlung!

Fake shop. Product is okay. They pretended to send it one week before it arrived in Japan. Reserved a shipping number from Sagawa before they even had the product.
