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

Works great !

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.

I’ve tried the rest Victron is best

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

The media could not be loaded. For more than twice the cost of other comparable units I expected a lot from Victron Energy MPPT. Unfortunately, the flaws in designs make this unit---and assume other VE MPPT as well because they use the software---unusable in many situations.The system is so overengineered it makes you wonder if its made for consumers at all. Here, I will just focus on two major ones that basically render the Victron Energy MPPT useless. I have attached a short video to illustrate them.The VE engineers believe the charging voltage must be 5V above the battery otherwise its pointless. So in everyday use, quite often their algorithm SmartSolar doesn't open the solar charging until 3-4 hours after the sunrise; the solar energy shows 0W more than 30% during the day and I am in southern Ca, the sunlight capital of the country. I don't care how smart VE engineers sound, that is a lot of energy to waste!The second major flaw is that VE SmartSolar algorithm thinks that if the load goes from 1W to 5W the whole output needs to be reset, so it turns off the load for 1 sec and reboot the output, and now my mini computer system and wifi network that are powered by VE controller just lose their power and connection. Yeah, I am sure those VE engineers will come up with a 100 reasons why rebooting is a good idea, but I don't care, because in practice I just cannot use a system that constantly cuts power to my critical equipments.BTW, those flaws are NOT setup related because I have gone thru all the settings.Other annoyances include there are no quick setup diagram or manual; it comes with a fine print dictionary size booklet you are supposed to read thru and understand the engineering genius behind the design. Seriously, in this day and age, why cannot a manufacture with so much resources and charging so much for their products devote a little bit effort in making setup steps intuitive for new users. And the battery current display has two digits after the decimal which is in A, but in reality only 0.1A shows, the second digit is always zero. So the precision VE MPPT claims is not really there. I never know if my system is drawing 0.11A or 0.19A, for example, because it doesn't show. So if you want to calculate the power consumption to design your solar system you cannot get it from VE MPPT.
