Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - MPPT Charge Controller for Solar Panels - 100V 15 amp 12/24-Volt

Works fine. Installed with no problems, only small problem was the pin required. I could not find it, so used the default that came up. Runs cool though not in full use yet, as I have only two panels feeding into it, and the load is being taken direct from the battery. Bluetooth and the information given in the statistics is fine, though a bit more range on the Bluetooth would be good. Well made and should last many years, at a fair price.

I replaced a Chinese MPPT that had almost impossible to follow instructions with this Victron. ‘Chalk and cheese’! The victron works brilliantly and was so easy to set up.

Probably the best quality MPPT money can buy. I have the 100/30 set up in my campervan on a 140w solar panel and it’s keeps my 2 140ah leisure batteries charged whenever I’m away on a trip. It’s very easy to set up and it’s pretty much plug and play. The Bluetooth app interface is also easy to use and provides good information for your electrical set up. Size wise it’s a big heavy unit but that shows the quality of it if you ask me. The efficiency is excellent and it’s never skipped a beat in my 2 years of ownership.

With only 175w of solar panels on my "Solar Shed", I've never wanted it to offset my normal house mains supply, but I did add 816Ah of flooded lead acid battery capacity and a 2.5 Kw mains inverter so that I could keep the fridge, freezer and some LED lights going for a couple of days if we ever get power cuts. On the weeks when the power is solid, I use the "Solar Shed" to do a couple of washing machine loads, and run the electric lawnmower. This has all worked fine in the summer but the old PWM controller that arrived with the panels, was struggling in the winter. So when it also developed an intermittent fault last week, I started researching a better replacement. The Victron unit is far superior in every respect. Firstly, it harvests about 15% more power at low light conditions than the PWM unit could, and secondly it is amazingly configurable, via its Bluetooth driven link with an App on your smartphone (see pics). I was particularly pleased to see that it can automatically run an equalisation charge at a voltage of your choice for a defined period after a user configurable period of days that can be over some weeks or months. It also allows you to just run one manually - ideal on a nice sunny day when the batteries are already "Floating" and you just want to get the Specific Gravities of all 18 cells to be nice and uniform. I have three top tips for you if you want to invest in this top quality controller:- A). Read the manual and pay careful attention to polarities when you connect the load, battery and PV positives and negatives. The battery is different, see.. B). When you download the APP and run it for the first time, it will automatically request access to Bluetooth itself and "find" the controller - Pass-Code is "000000" (Six Zeroes) C). If you don't want the load to be "Permanently on" (The default), then you will have to install and run the App, go to "Settings" (The wee Cog) and change it to "Permanently off".

Victron equipment is pricey but based upon this piece of kit I purchased it is worth it. The install was simple and the data from the bluetooth is very valuable for monitoring the system. I really like it and would be going fully with this brand if it were not so much more expensive than others.

It’s a brilliant bit of kit! It charges battery’s and easy to set up, iv recently upgraded from a generic not mppt solar charger and it was not stopping charging at 100% giving me voltage problems and it would charge slowly. This on the other hand, iv hooked it up put the setting of the battery In and it just works! No voltage problems and charging faster than the old one! My advice is to spend the money! You get what you pay for!!!

This Victron MPPT charger is now my second one. Victron Solar products are excellent, well made and functional. This 100/20 charger has been installed on my small 3 x 100W array. It is working fantastically. Installation and setup is a breeze - the free phone app makes monitoring the Solar input (watts) and voltages of your array and battery easy to understand and monitor. There are a ton of charging profiles already stored in the controller covering pretty much every battery you could wish to charger from SLA, AGM to LIFEPO4. The controller is monitored via Bluetooth - this is where Victron let themselves down slightly, the Bluetooth range is very poor, i loose connection in the next room and my house is a new build so doesn't even have thick stone/brick walls. There is also no remote monitoring without purchasing an additional £300 module. The Bluetooth module in the MPPT controller also does not work with Windows PC's, it will work fine with MAC OS. Victron publicly stated over 2 years ago they were working on a Bluetooth compatibility fix for this, but as of today it is still not compatible with windows PC's. The only option for us windows users is to purchase a Victron USB cable and tether to the controller via a wire, which is impracticable for most people. Hopefully one day windows bluetooth compatibility will come, then this product will truly be worthy of 5 stars! I hope that you found my review helpful.

This Victron MPPT controller is a great upgrade to my vans solar system, I was really struggeling to keep the leisure batteries charged with the cheap PMW contoller that came as part of the kit with my solar panels. Now even on the dullest, rainy Scottish November days I can acheive a full charge. Well worth buying.

Had eerst de 75/15 Victron 4mm² aansluiting. gekocht maar die is voor de koeling gevuld met kanariezand. Dach al! waar komt dat zand vandaan. Voor iets meer nu de 100/30 van Victron met koelribben. Veel degelijker. Voor max 440Wp paneel En invoer je kunt 6 mm² kabel gebruiken. ( Voor de camper bus. )

Provato quasi tutte le funzioni del Victron e devo dire che funziona tutto alla perfezione. Il collegamento wifi e l'app sono semplicissime da utilizzare e abbastanza complete anche in termini di statistiche. Il prodotto sembra robusto fatto di buoni materiali. La morsettiera e' vermente fatta bene e ben dimensionata per il mio 15A. Le impostazioni del caricatore, tutte impostabili con app in wifi, sono veramete elementari, il voltaggio della batteria la riconosce automaticamente e per ciascuna tipologia e' tutto preimpostato ma se si vuole si possono cambiare i parametri. E' un MPPT al 100%, infatti aggiusta la potenza assorbita in funziona di quella massima disponibile. La corrente erogata a carico da servire (load + batteria) e' maggiore di quella in ingresso da FV ed a tensione inferiore (12 o 24v) come deve essere per un Buck converter. La gestione del carico funziona bene sia in termini di programmazione sia in termini di gestione della potenza. Provato varie situazioni (ad esempio Potenza FV > e < di quella richiesta da carico e dal caricabatteria etc). Funziona veramente bene, come un orologio, un prodotto semplice ma professionale che non crea sorprese. Ho letto di molti MPPT che si comportano in modo strano nella gestione del carico. Ad esempio ho letto di caricatori che non gestiscono correttamente attivazione/disattivazione carico a seguito transizione giorno notte, notte giorno e giorno notte (hai detto niente!!! da buttare) o altre situazioni strane. Non ha ventola e quindi e' silenziosissimo ed io non sono riuscito a farlo scaldare fino a 80W assorbiti. Il prodotto e' eccellente ma ha un lato negativo, il costo che non e' proprio economico soprattutto per correnti da 20a in su. Comunque se non volete problemi e non volete andare a caccia di problemi ve lo consiglio vivamente, io non mi addentrerei in caricatori MPPT da 100A che costano pochissimo, anzi, ve li regalano addirittura, il perche' lo scoprereste certamente in seguito.

Great as any good manufactured by VICTRON

Très bien conforme et moins cher que chez beaucoup de vendeur. Je recommande.

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.
