Victron BlueSolar MPPT Charge Controller 150/45
SCC115045222 - The Victron MPPT controller will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement, of the battery plus load. Thus, it essentially decouples the array and battery voltages so that there can be, for example, a 12 volt battery on one side of the MPPT charge controller and a large number of cells wired in series to produce 36 volts on the other. To fully exploit the potential of the MPPT controller, the array voltage should be substantially higher than the battery voltage. The MPPT controller is the solution of choice for higher power systems because of the lowest overall system cost due to smaller cable cross sectional areas. It will also harvest substantially more power when the solar cell temperature is low (below 45 C), or very high (above 75 C), or when irradiance is very low.

Great unit. Solidly built. I purchased it for a 100w panel that i had purchased for my sailboat.My first foray into solar power. I confess the original Charge Controller I purchased with the panel was a cheap one made of plastic. The wire connections to the Controller would not stay attached, even though I stepped them down to # 10 gauge. Infuriating! The replacement Victron product had great instructions and is built solidly. One complaint: same as the previous Charge Controller, twice now a wire has come loose from the Charge Controller box. This should not happen. The compression screws and plates should grab the wire more securely. I have really screwed them down hard now, but I still find myself checking them every once in a while while underway in a sea.

I happened upon this charger while trying to find a cheaper alternative to the Morningstar SunSaver MPPT, also a 75V input to 12/24 at 15A. This charger is nearly a third of the price and has the most important feature "According To Me": end of charge detection and termination. Unlike other MPPT chargers, this one monitors the battery current and stops charging when charging is complete instead of blindly absorption charging for a fixed time regardless of whether the battery is charged or not. You also don't need an expensive Bluetooth or serial connection for the Victron Connect to detect and configure the charger. If you have some basic electronics experience, a cheap chinesium grade cp2102 USB-UART adapter for your Arduino (not required) and 3 wires with DuPont ... MoreI happened upon this charger while trying to find a cheaper alternative to the Morningstar SunSaver MPPT, also a 75V input to 12/24 at 15A.

Victron has also embraced the IoT and Open Source communities which means that if you're like me and want to write your own monitoring system the VE.Direct protocol as well as connector pinouts are documented and there's some source code examples.

I installed the Victron 75/15 BlueSolar and BT module a couple of months ago as part of a complete re-vamp of the solar installation on our camper. Combined with a Renogy 100w panel, I'm getting great results on keeping the house battery charged, and the data and control provided by the VictronConnect app is a huge improvement over the primitive info I had available before (a charge-indicator LED and a volt-meter). The unit is mostly easy to install (more on that later) and functions brilliantly. There are a few minor flaws that cost the overall review 1-star: 1) The Battery/PV connection points use the screw-down terminal sockets where you insert the bare-end of a wire into a slot and tighten the screw. Maximum is ~10AWG that will fit into this hole.

Maximum is ~10AWG that will fit into this hole. If you're attempting any sort of parallel installation (either parallel PV panels, or in my case two parallel input cables so that I can swap between hard-wired and the panel detached from the roof and run with a long cable), you will need to get creative or use an outboard terminal block. Zero chance of jamming two braided 12AWG wires into one hole. I REALLY wish Victron had used a terminal block which accepted ring terminals. Most people could use a crimp tool, so this isn't a high barrier to a quality installation. The other issue with this slot-terminal system is that if you have the controller mounted low (like down in a utility cabinet, near your battery, per the instructions), it can be very hard to see the slots to correctly insert the wires. I've taken to dis-mounting the controller any time I need to deal with the wiring, then re-attaching it to the wall. Bummer. 2) The connector for the Bluetooth module is a small multi-pin flat connector that does not lock very securely. I have accidentally knocked it out on a couple of occasions just by putting tension on the cable. (And see above re: difficulty re-attaching cables if you can't see the bottom of the controller.) A locking connector here would be great. Some folks may opt for the other Victron unit that has built-in BT, but apparently the MOSFETs in that unit aren't the same, so it isn't strictly "outboard" vs "built-in" BT as a comparison. 3) The VictronConnect app overall is good, but has some usability issues. If you de-focus the app at all (i.e. switch to any other app, even briefly), it forces you to re-sync to the controller when you re-open the app. While trying to do something like read a Battery datasheet to transfer the critical charge parameters (max current, max voltage, etc.) to the Battery setup, this was a huge pain, as simply switching between the browser to see the parameters then switching back to the Battery setup in the app forced me to re-sync on EVERY context switch. This means re-selecting the controller (from a list of one, I guess some folks have several?), then re-selecting the Settings block, then re-opening the Battery tab, etc. etc. for each item. 4) As a general rule, blinking lights should be for things that demand your attention. The Bluetooth module blinks a bright-blue LED whenever you are NOT connected via BT. (And see #3 - this happens constantly!) I wanted to place this module someplace easy to see (so I could diagnose issues at a glance), but at night this blinking LED is bright enough to be annoying, so my choices are to bury the module inside a cabinet where it will not be visible, or to put a spot of tape over the LED - either solution nerfing the whole "at a glance" convenience.

It works very well, nice bluetooth app, reacts to voltage changes and all; the downer to me was that I couldn't get more than 220Watts off it (12Vdc system), so that meant I had to go for a bigger one and they get expensive. At first I thought, since the Vdc is 75 and Adc 15, I must be able to connect two 270w panels in series, right? Well, then I realized the controller's max output would be 220W. That means it is good for only one of my 270W and probably waste a potential 50W for part of the day. Anyways, it works well, just pay more attention next time. hope this comment helps other people.
Works as expected. I wish I had seen that it doesn't have bluetooth before I ordered it. My fault. Excellent product, but with no display and no bluetooth, it requires external metering to see how much voltage and power you are getting.
First of all, I would like to say thank you to ML Performance for making this purchase possible. I have to say its a smooth, fast and easy experience! And I would definitely recommend to anyone out there who wants to order BMWparts. 100% trusted & legit seller!!Looking forward for my next purchase from you guys. Keep it up ML Performace!
Well, I just wanted to give my opinion. I made the normal purchase like any other customer. A few days later I had a problem. I had to make an important trip. Contact ml performance by email to say that the contact service via email is spectacular. I never had a service like that with another store. well I told them that I needed the super urgent material. and well after a great job of coordination and good work from ml performance I received the material and everything went perfect. In general I recommend ml performance and I hope to work with them again in future purchases. thank you
I ordered this item during the COVID-19 pandemic (still on-going) and expected a large delay. There was never a period of uncertainty. Communication is second to none and the 'working from home' policy is a different level as I even received an e-mail at 2330 at night MLPerformance is a fantastic company and I will not hesitate to use them again. You even get a personal message from them in the package, a nice touch. I wish them all the success and support possible during these testing times. Phenomenal.
We all know how important it is to build a good customer base. The secret to success is to remain competitive and offer great service. ML Performance achieve both of those goals.I asked questions about my purchase before hitting buy. I had a reply quickly and great guidance. The email not only gave me the answer I needed but a link to the right product. Saving me time and confusion.The item arrived as described and was well packaged.I cannot wait to pop the part on my car.Great job ML. I will be coming back soon.
I have been really impressed with ML Performance. The website was easy to use and the response to my questions rapid. My itemswere delivered within 48 hrs. There was also a hand-written note from Charlotte in the packaging which was a great touch. Really good service and will definitely use again. Many thanks
