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

The Victron 75/15 smart charge controller is working exactly as it should and I have been using it for 30 days and have had no problems whatsoever. Victron is a quality product and is extremely simple to set up. The Bluetooth function works well with the app and offers plenty of information. Highly recommend.!

I have to say some kind words so far for this charge controller, in short, this is an amazing product. Early in its use, I have a small outdoor solar array using batteries to power a sprinkler system, sound system, lighting and an outlet using a separate inverter. We live on top of a hill, no trees, no wind blocks and get the worst of the weather constantly. I have been through many MANY MPPT Solar Charge Controllers and was a bit scared to go with a Bluetooth only controlled device. I was quickly impressed with the VictronConnect software, giving a demo device so I could test drive the settings and see exactly what I would get and control. Next up, how hard is it to connect and reconnect once I got physical hardware.... It was literally as easy as the demo equipment. I was able to power on the controller using Solar power OR battery, meaning as long as you have 1 power source it just works. Bluetooth connected instantly, one tap on my Android phone and the PIN on side of the controller and I was done. I did notice that the default for me was 24v when I had a 12v battery connected but that wasn't a big deal, went through set to 12 and was all set. Because I do a lot of work with solar controllers, I wanted to see how accurate and fast this little beast was on the phone app, ran a constant 25w load and the app was within a half second reporting accurately. Variable loads also gave good information, up to this point I was already sold that this was a solid device. The app is just about perfect, gives you Amp and Watt usage which is nice for quick math and efficiency conversion. I also really like that the battery stats show when your load is pulling from solar only or from battery, very clever and easy to read. Pros: Super easy to install, Plug and Play Easy to configure easy AND expert settings Complete customization of battery settings and a good number of presets Was able to configure exact settings for my 12.8v LiFePO4 battery! Feels solid and I have no doubt that it will last in harsh environments Easy to mount, Good size fits just about anywhere Easily control load on/off depending on solar input Cons: Cant find any yet but here are some things to note Mine defaulted to 24v, easy change to 12, maybe sensitive batteries and large systems might have connection issues Would be nice to have a day timer for on/off functions as well as solar input but this is being super picky If you are looking for a good MPPT Solar Charge Controller, feature rich and don't mind using your phone and Bluetooth to configure, this is the one you want. Can't comment on longevity thus far but I have no doubts this will last! Will update if anything changes...

I use this charge controller between a solar panel and a battery. The panel is a single 120-Watt 12/24-Volt unit with a maximum (open circuit) voltage of 33.7 V. The battery is a pair of 12-Volt lead-acid batteries wired in series to make 24V. It appears to be working well. It charges and maintains the batteries at about 25.8 Volts. The controller is easy to wire and set up. The iPhone app took some fiddling around to get going - a couple extra minutes that may have been my fault. Once up and running the app connects the phone to the controller via Bluetooth over a modest distance, maybe 10 yards. The app shows charge current, panel voltage, charge power, and battery voltage. The controller is compact and appears to be solidly made. I would buy another if I have the need.

With the phone app and Bluetooth connectivity, this controller is the best I've ever used. I was using other controllers with the digital screens until the purchase. The app provides a significantly better experience than any digital on-controller screen could. Victron is my new go-to brand. This controller is used to manage the electric fence around my cattle pastures - I need something reliable to keep the cattle in and the wild hogs out.

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.

ottimo prodotto e facile da installare e configurare

De momento satisfecho con el producto, comparado con mi controlador chinorris anterior que no ofrecía ningún dato sobre consumo o amperaje o potencia es un gran salto de calidad. Se nota cómo cuando la placa está aportando por ejemplo 3A, desde el controlador a la batería está enviando en torno a un 30 o 40% más de amperaje al convertir el voltaje sobrante también en energía aprovechable. En un panel de 125w, me ha registrado puntos de potencia de 115w. El voltaje en la salida Load lo veo bastante estable, incluso con la batería a tope, cosa que mi anterior controlador PWM se quedaba cómo conectando y desconectando los paneles y provocaba cambios bruscos en el voltaje de alimentación de la nevera 12v que he conectado para probar. Este sí que le mantiene un voltaje estable. Además con la batería en flotación limita la potencia de la placa adaptandola a lo que necesita el sistema, pasando de 10 o 12w de la carga de mantenimiento, a 75w cuando he conectado la nevera (38w) y un pequeño inversor para cargar el móvil, de manera que mantenía el pequeño flujo de 0.5A aproximadamente hacía la batería y aportaba el resto de amperaje directamente a los aparatos conectados. Mi única duda es en días nublados o con el panel en sombra qué el amperaje que me aporta es muy bajo, cosa de 0.5 A, 0.6 en las primeras horas de la mañana, pero puede que se deba a que la placa no proporcione más en esas condiciones, ahí no tengo datos de qué haría otro controlador. Este lo veo muy completo, ofrece un montón de datos por bluetooth al móvil. Si llevara wifi para acceder a esos datos a través de Internet ya sería genial, pero bueno, no se puede pedir todo.

Lätt att installera, perfekt app och gick att ha på svenska

Really good piece of kit
