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

Purchased several of these charge controllers. Great compact design and a reasonable price point. Very easy install. The Bluetooth model has a lot of features and functions…….this is my go to charge controller.Cons: none

What I liked:- Easy to use App- App even creates a network with the Victron SmartShunt and communicates with it- The MPPT tracking is fast and I get full power from 100 watt panels. In fact, I've gotten 214 watts from two 100-watt panels in series.-Bluetooth works great and I can easily setup all the battery parameters via the app

Nice packaging, well-functioning phone app, built-in bluetooth that you don't need to pay extra for (hear that Renogy? although, in Renogy's defense, their controllers have a display, whereas this one- you really need to have the app to see what it's doing), small and easy to mount. Yes- pay a little extra and get a good MPPT controller rather than one of those cheap PWM ones for your RV solar setup. Seems to work great.I guess I do have one complaint. I have 10AWG wires going into it, which *barely* fit into the connectors. I think they're sized for 12 gauge. Granted, given the amp rating on this, 10 gauge is overkill.

Works like a charm and is easy to setup. Went back to buy 6 more and there was a limit of one unless you have a commercial amazon account? Went and bought them elsewhere, thanks for the intro amazon.

Easy to install and the app to monitor and configure the unit from your phone works great.

This solar charge controller comes with Bluetooth and is a bit higher in price than the competition, but for good reason. Victron makes high quality products and backs them up with a 5-year warranty and support. You can adjust the amount of power it delivers to your batteries too. I have 800w of panels in a somewhat low light area and I'm able to bring in a solid 430w of power at the 15A charge setting (max for this controller) even in low light. Just don't go over the Voltage rating. 100V is a HARD limit, meaning if you surpass it, it will damage the controller. I'll need to upgrade it soon so I can get all the available power from my panels. I also love the integration between the different products and the open source nature of the company. The fact I can use a Raspberry Pi to run Victron's Venus OS and any good quality USB to TTY serial adapter to connect it all is a HUGE win for Victron. The phone app is also well designed and they even offer free logging of your data to their VRM web portal. I'll be coming back to Victron for more stuff in the near future.

This is a good little MPPT Controller, Bluetooth, efficient and does what it's supposed to do . It also has a Load Output to prevent from draining your battery flat. My only gripe is the specs say the terminals can accept 10AWG or 6mm2. While a bare, stranded 10AWG wire will fit, if you use Ferrules, it will not fit in the terminal. The largest wire this controller will take with a Ferrule installed is about 12AWG. I use Ferrules on ALL connections that use a clamp down terminal. I never allow bare strand wire to be clamped down by the terminal. If you do this, it will smash the wire, spreading it apart, and not allow for a secure connection. Yes, it will work but, with the amount of vibration in a Boat or RV, the use of Ferrules will make for a more secure connection. I returned the 100-15 and purchased a 100-30 Smart Solar MPPT. The 100-30 is the smallest Controller that will accept 6AWG Ferrules. I use 4AWG wire and crimp on 6AWG Ferrules. Works perfect and when cut apart to inspect, the copper is so tight, it's almost welded together from the amount of force the ferrules crimp down. FYI, the wire and crimp tools I use are from TemCo. While this controller doesn't need anything bigger than 12AWG wire, I always oversize my conductors for low loss and room for expansion (Future Proofed). Hope this helps someone make the proper choice for their application.

Works great !
