Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - MPPT Charge Controller for Solar Panels - 100V 30 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 defaultthat 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.

The media could not be loaded. It’s a brilliant bit of kit! It charges battery’s and easy to set up, iv recently upgraded from a generic not mppt solar charger and it was not stopping charging at 100% giving me voltage problems and it would charge slowly. This on the other hand, iv hooked it up put the setting of the battery In and it just works! No voltage problems and charging faster than the old one! My advice is to spend the money! You get what you pay for!!!

Victron equipment is pricey but based upon this piece of kit I purchased it is worth it. The install was simple and the data from the bluetooth is very valuable for monitoring the system. I really like it and would be going fully with this brand if it were not so much more expensive than others.

Probably the best quality MPPT money can buy. I have the 100/30 set up in my campervan on a 140w solar panel and it’s keeps my 2 140ah leisure batteries charged whenever I’m away on a trip. It’s very easy to set up and it’s pretty much plug and play. The Bluetooth app interface is also easy to use and provides good information for your electrical set up. Size wise it’s a big heavy unit but that shows the quality of it if you ask me. The efficiency is excellent and it’s never skipped a beat in my 2 years of ownership.

Bit pricey, but worth the money just connect the wires and that's it all done. Nothing to set up.Connect to the app on the phone and you can see what is happening.very good bit of equipment.Build quality is very nice

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".

This Victron MPPT charger is now my second one. Victron Solar products are excellent, well made and functional. This 100/20 charger has been installed on my small 3 x 100W array. It is working fantastically. Installation and setup is a breeze - the free phone app makes monitoring the Solar input (watts) and voltages of your array and battery easy to understand and monitor. There are a ton of charging profiles already stored in the controller covering pretty much every battery you could wish to charger from SLA, AGM to LIFEPO4. The controller is monitored via Bluetooth - this is where Victron let themselves down slightly, the Bluetooth range is very poor, i loose connection in the next room and my house is a new build so doesn't even have thick stone/brick walls. There is also no remote monitoring without purchasing an additional £300 module. The Bluetooth module in the MPPT controller also does not work with Windows PC's, it will work fine with MAC OS. Victron publicly stated over 2 years ago they were working on a Bluetooth compatibility fix for this, but as of today it is still not compatible with windows PC's. The only option for us windows users is to purchase a Victron USB cable and tether to the controller via a wire, which is impracticable for most people. Hopefully one day windows bluetooth compatibility will come, then this product will truly be worthy of 5 stars!I hope that you found my review helpful.

Cut my old Sargent solar controller out today, used the old wires and wired it in, what a difference I can now see why the door panel is doing and whatState the battery is think I went a bit over board as I only have a 40w solar panel in the caravan. It it’s enough to keep battery charged over winter and I can always up grade the panel on the roof if I wanted or add more panels
