BlueSolar MPPT Solar Charge Controller - Charge Controllers for Solar Panels - 100V, 15 amp, 12/24-Volt

Very nice unit but I didn’t know it was that small and I figured it would not meet my needs so I had to return it for it bigger brother 150/70 unit. I see reviews on YouTube and I came to realize this unit would be too small for my project and I needed a larger unit with more amperage. I will update when I get my new unit.

Connected to both 12V nominal panel and a 48V panel and they both worked great. MPPT charge controllers have really come down in price over the years, and victron is a somewhat respected name. This is just an important heads up and the true purpose of my review. This model does not include integrated Bluetooth technology. For connectivity you have to buy a dongle, currently around $40 to connect, or just buy the Bluetooth model of this unit for only an additional $15.00. If you don't want or need connectivity, fine- buy this one and save a few bucks. But I love the information that the Bluetooth connectivity will give you and in my mind it's worth the extra 15.00. In a portable setup it will allow you to position your panels to optimal angles and see incoming watts, as well as the state of the charge of the battery. You can also easily make adjustments to the charging profile if desired.

Works great so far. Have had for over 2 years and still works. I feel this was a great buy.

I feel tricked that this was Bluetooth ready. In the pictures it shows it connected to the Victron app. Only after installing and doing lots of searching, I find that it needs the Bluetooth dongle to use the app. Its not a problem getting the dongle. The problem is my time wasted researching what I need and why it wouldn't connect. It needs to be clear from the get go on what is needed. I would have paid more for a unit that had Bluetooth ready. Just seems like a deception tactic. They need clear indication on what all is needed. Or if there is another option that has these specs but does have Bluetooth. I see by the comments many people have had this same problem. Many have sent it back. Do better VICTRON.

Good quality

Bought this after several YouTube and Amazon reviews and very glad I did. My other MVP controller failed so It needed replacement. I made a system upgrade to lithium Life-po 4 batteries also and added new floor panels along with my roof ones. At first it didn't work so I contracted Victron support. They spent about an hour on the phone with me going through various tests until we found the likely source of the problem - the 300 amp fuse unit. I replace that and it worked like a dream and has been going ever since. The Bluetooth is so handy and the size of the unit is so compact compared with other behemoth controllers.

As many have remarked, the terminals could be better. Otherwise an excellent contoller.

Does a good job once it starts charging. My other controllers starts charging with less solar.
