SmartSolar MPPT Solar Charge Controller (Bluetooth) - MPPT Charge Controller for Solar Panels - 75V 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.

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".

As described. Easy to install. Works great.

Brilliant solar controller. Easy install. Monitoring via the app is a cinch

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.

Very good high quality kit and simple to install

Great piece of kit, works beautifully and the Bluetooth app is superb but whoever set up/designed the provided battery profiles needs to go back and look at them again. I didn’t recognise a single profile offered, all we need is say, Flood, Gel, AGM, Lithium and perhaps a few other exotics. OK you can go in and set up your own battery profile but it’s really difficult to find these on the web and it’s fiddly and unnecessary. Come on Victron give us some realistic, workable battery profiles which people recognise.

VictronConnect app is impressive.

Solar energy is a great way to have back-up power for your home or for your RV. Solar isn't super complicated, but there are a lot of things you need to know to make the best purchases. Solar charges (like the Victron) come in both PWM and MPPT. PWM are significantly less expensive, but may fit your needs. MPPT is a better option, and this very affordable Victron unit is a fantastic entry-level charge controller. It's 75/15 name refers to the maximum volts it will accept/use from your solar array, and the 15 amps it can accept/use. The Victron Smart Solar 75/15 can handle up to 300 watts of solar panels wired in series or parallel. In series, that's about 68 volts max, well within tolerances, or 16.5 amps max which will be capped at 15 amps. Truth is, except for perfect sun and panel angle, you're not likely to hit the 16.5 amps. Still, that's not bad! A great part of the Victron 75/15 design is that it has bluetooth built in, so don't need to shell out extra for a dongle. Note: if you want this, look for the "Smart Solar," if it doesn't say this, you'll need a dongle. The size of this unit is just excellent; I bought it for my DIY powerstation. It works great, giving me nearly the full 100 watts from my Renogy solar panels under ideal conditions. For the money (about $65 at the time of purchase) it's simple enough for the beginners, or strong enough to manage a modest RV. Cons: It uses small, flat-head screws, so you'll need a small "pocket" screwdriver to make the connections. The input for the wires is pretty small. I had a ferrule kit, so I was able to insert 12 AWG with no trouble. I don't know how you'd easily get 10 AWG (somewhat standard for solar) but what I had worked and I'm happy.

does the job buy again.

Great solar mppt

Va genial,te informa en todo momento y con información en tiempo real de la gestión de carga gracias a su conexión bluetooth, está muy bien de tamaño porque no ocupa mucho espacio, fácil de usar y muy completo.

We've had it installed one summer in our boat and it does what it's expected to do. Perfect shipping and easy to install!
