Victron Energy MPPT 75|15 Charging Controllers

Got this to replace my cheap chinese controller and the difference in charging capacity and the control you have is amazing.Not cheap but I still think it was worth every penny.

The item is well made and easy to fit....BUT....bluetooth connectivity fails when attempting to pair the device with my iPhone or Macbook Pro computer, so I am unable to monitor it', and the solar panels, performance. I have therefor given 3 stars for "easy to install" as installation was impossible to complete. This seems to be a common fault judging by the number of people who have been as unsuccessful as me when trying to pair the device. The advice is to refer to the pairing instructions but despitefollowing instructions to the letter it does not work. The connection, like many other folks, fails at 80%. There appear to be no solutions. I therefor cannot recommend this device. What I would recommend is buy the item without bluetooth (Victron BlueSolar)....it is cheaper.

Just the job, very good quality easy to install and to set up on the Bluetooth, perfect

I had been using a ring controller and this didn't seem to work correctly, seen some reviews on the Victron systems and though what have I got to lose.it took me about 30 minutes to do the swap over and go through the settings screen, this was easy and simple as there is a lot of info available on the Victron site, all managed through the free app, ohh boy what a difference this made, instant data and charging my batteries at around 10amps at the time.I find myself sitting watching the app on the smart phone to see how much the batteries are charging, how much sun I'm getting...I would recommend these systems to anyone looking for a good MPPT system along with there solar panels, brilliant bit of kit...

We have used this in our motorhome with our 160w solar panel and its fantastic. You can see so much information via the app and change settings etc. We have had it up and running a good few weeks now and can't fault it.

Very good product, working well so far, fully programmable via the built in Bluetooth. Plenty of setting up info on YouTube( Be carefully only the smart version has built in Bluetooth). The only down side is Bluetooth has short range, Not the cheapest out there but you get what you pay for. Comes highly recommended, other than that can't fault it.

I purchased this to charge new renogy lifepo4 & lead acid battery via a Dokio 160w portable solar panel and it works very well. The application is very easy to use and instructions easy to follow, there are multiple profiles for different types of batteries. One important instruction to follow is to attach the battery connector first before the solar otherwise you could risk damaging the charge controller.

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".
