Victron Energy BlueSolar MPPT Solar Charge Controller - Charge Controllers for Solar Panels - 150V, 35 amp, 12/24/36/48-Volt

How refreshing. A budget priced, well engineered product. Well engineered, because all the details are well thought out. From the design of the circuit board, to the user interface, to the array of remote options, to the well organized plain English printed documentation. I also have a $700 MidNite Classic controller for another system. Very reliable and versatile charge controller. But this much lower priced unit does most of what the Classic can do, including custom settings for LFP batteries and remote monitoring.I almost went with one of the popular Chinese made EPEVER controllers, and in fact ordered one, but the product as a whole is just a mess. Confusing, uncommonly labeled settings, programming limitations, funky and confusing remote monitoring options, etc. I finally came across a guy on utube that had posted a video describing how the addition of a Victron charge controller solved the problems he had been having with his two EPEVER controllers. That cinched it. I returned the EPEVER unit, ordered the Victron unit, banked the $100 difference in price and never looked back.NigglesOk. No product is perfect. Victron markets a version of this controller with built in Bluetooth for remote monitoring. But they also sell a version where the Bluetooth can be a plug in add-on, which is great if you need to place the Bluetooth dongle in a better location for reception. My solar equipment is housed in a large, thick metal housing, so being able to place the dongle externally and pass the cable through the box and plug it into the controller was a great option. However, Victron designed the plug with a rectangular connector instead of a round one. Small design choice, but it kept me from being able to use one of those neat waterproof pass-through glands to seal the hole. You have to use a gland large enough to pass the plug through, but then the gland is too large to close down completely on the cable. Thus, not a waterproof connection.Very happy with my Victron controller!

Works as advertised

Love the Victron products. Be careful though, I did not realize they made this item without Bluetooth. When paired with the Bluetooth module, it does not properly network into the system with the controllers with Bluetooth built in. It does work, but not quite the same.

Im using them to charge up my 48v system comprised of 4 12v batteries out in the pasture. They power the solar well pump to bring water to tanks where there is no electricity available. No issues as expected from victron.

Blue is NOT Bluetooth! VERY misleading. If you want bluetooth, look for the SMARTblue unit, $40 more, or get the ve to bluetooth dangle for $40,your choice. Other than that ,the unit is Fantastic, works great right out of the box. GET ONE!

Love this machine. Installed it on my of grid cabin a few months ago and it hasn't missed beat. Good design, materials. Love it.

In my opinion the best brand of controller on the market. I have several and can share data with the app, make changes across all of them by the app and keep the updated with the app. What else do you need? They simply work

This mppt captures and improves what the solar pannels produce. I’ve used half a dozen solar controllers, but the Victron out performs them all, including midnight kid.
