Victron Energy SmartSolar MPPT Solar Charge Controller 75V 15A 12/24V

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.

Very good i think it has made a big difference to my solar set up

I have a campervan with a 100W solar panel and 2 x batteries 220amp total. I'm impressed with this, well made and is easy to setup. Built in Bluetooth and app is great. Manual is okay but do your research on meanings of certain functions such as absorption. The MPPT seems to draw from the solar only what it needs which is clever and regulates the power. I had a fridge, 1000W Inverter running and charging 2 phones and MPPT was brilliant see 100W PHOTO. It drew power from the solar to supply what was being used and maintained the float charge very clever. You got to get one they are ace but a bit pricey. Update- I posted a question about this item about why my battery voltage (12.73v) at the controller was different to the battery voltage with a voltmeter (12.3v). Through some research it is because the cable between the controller and the battery terminals is to thin. So I put in thicker cable and it has worked perfectly. Both the voltmeter readings and the controller readings are exactly the same so now i know what state of charge the batteries are at. Really great controller.

Fantastic does exactly what it says on the box great value for money easy to install

Fitted this in my VW camper which runs a 150w panel and LifePO4 battery. Very quick to fit and adjust the charge profile. Victron app is stable to use, I have an old iphone dedicated to running the app so I can quickly see what's going on. 15amp maximum charge is fine for my use and this unit is compact enough to fit into a tight space. Only criticism is that connections are specified to take 10AWG cable but they're a bit too small. I have very short cable runs from DC MCBs to the MPPT for the panel and battery, so I stepped down on the cable size for these. Also note that the load output isn't really designed for accessories that draw a large startup current (fridge or inverter) - it's sensitive and it'll shut down when these start up. Fine for everything else though, so I have fridge and inverter wired directly through a fused connection to the battery. It means you can't monitor the total current draw via the app but to be honest you just need to see the incoming charge and battery voltage to confirm that everything is working and charging as it should. Highly recommended and very good price.

Amazing controller! I recently purchased a new solar panel because it did not appear to be powerful enough, at the same time I decided to buy this controller... the difference the new setup made was fantastic! Out of interest, I coupled up my old solar panel, only to find that there was nothing at all wrong with it, it was down to a poor quality controller! This controller manages to get the very best performance from you solar panel and you can monitor all the live and 30 days of data on your phone via bluetooth. Highly recommended.

Great bit of kit but who the hell thought it was a good idea to basically use a strobe light to indicate the solar charger is off at night? It's SO bright and I had to put tape over it because it drove me insane. Seriously it's been used in campervans and boats so sure someone should have thought to tone it down

Having started off with a quick solar kit only to learn that the solar controller that came with the kit was not very effective. Hearing lots of people stating this brand is top-notch, which I completely agree as I was able to get close to max at 198w from a good sunny day from 2x 120w panels. Well, my previous one would barely get 120w from those two panels which is, not to mention, pretty poor. Therefore I recommend you take a look and try it out. I also got the 100/20 one connected to a 200ah life4po battery

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.

This is an excellent charge controller, loaded with features, very compact, very reliable. The ability to use an app to track the solar metrics extends beyond just that capability. In my case (as a software developer and electronics tinkerer type person), I'm using an ESP32 module (about $6) to capture the Bluetooth broadcast data from the charge controller and upload it to my website, where I can easily monitor the solar performance of my camper remotely. I'm using the VictronBLE ESP32 library with additional code to upload the data to my web server. This charge controller supports around 200 Watts of solar if your battery(s) are 12 V, and around 400 Watts if your battery(s) are 24 V (15 A x 12 V = 180W, 15 A x 24 V = 360 W, however since the charge voltage is a little higher than your battery voltage, it is right around 200 W and 400 W). I'm running 400 Watts of solar (2 x 200 W) with a 12 V battery, so the charge controller can really only make use of about half of my maximum solar power. However, the upside is that on a cloudy day when the panels cannot produce their full power, having double the solar results in double the wattage (IE if one panel can only produce 30 watts on a very overcast day, then I get 60 watts with double the panels). The charge controller handles this just fine - it only allows up to the 15A to flow even if the panels can produce more. I highly recommend this controller. If you don't understand the relationship between the amperage of the controller, the battery voltage, and the wattage, then use AI or research it yourself a little. It isn't too complex. Essentially for this controller, the 75V is the maximum solar voltage it can handle (and that is determined by the properties of your solar panels, and whether you have then in serial or parallel combinations), 15A is the maximum amperage it can send to a battery or load, and 12/24 means it works with both 12V and 24V battery setups.

does the job buy again.
