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

A great addition to my 12V solar system. Received and setup very quickly. I have had other charge controllers that were extremely hard to set up. This one was a breeze.

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

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.

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

I went off grid at my home 4 years ago and bought all Victron components (charge controllers, inverters, monitors, etc.). They have performed flawlessly. Victron stuff costs a bit more, but it's worth it!When I upgraded my camper with LiFePO4 batteries, I had to buy a new charge controller. I tried to save a few bucks by ordering another brand for my camper. It worked OK for about 2 years and then died. I am a radio amateur operator and that CC put out a lot of radio interference. I had to turn it off when I was operating my radio.When the non-VIctron CC died, I went back to Victron. It works great and no radio interference.Stick with best and save yourself unnecessary headaches. Buy Victon.

Absolute game changer from the Renogy Wanderer. It keeps my batteries at a constant with no deviation or overpower. 300ah Lithium Battery, 200 watt Renogy panel, never without power while camping.

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.
