Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 150V 35 amp 12/24/36/48-Volt

This 150/35 is my third Victron Smartsolar MPPT solar charge controller. They are great quality and function well no matter the configuration. This unit will be used to add more solar to our off grid cabin. We also use a 75/15 that is used in an ammo box with a 20Ah battery and multiple usb outlets, 12v sockets 2.5x5.5 barrel connectors etc. We also purchased a 100/20 which is used for maintaining car batteries, charging a 48V ebike, charging outdoor lighting batteries. The 150/35 and 100/20 can charge 12, 24, 36, 48 volt batteries if your solar array has the correct voltage to do so. These need 5v above battery voltage to start charging and 1-2volts above battery voltage to continue charging. Never exceed the voltage limit and remember that voltage goes up when your solar panels get cold, so account for this when setting up your system. The Victron Connect app is great and works through bluetooth. You are able to adjust all charging parameters in the app through your phone with a nice and logical app. Victron release updates fairly frequently and they are always an improvement, I have never regretted an update like one might with a computer or cell phone. Another positive to this is that the updates are stores in the app, so you can take your phone to a place where you have a comtroller needing an udate and successfully update it with no cell service. Top quailty product with great features. I will purchase more in the future.

Excellent purchase, work flawless

So far works great. Using 48V. It knows the state of batteries. Currently have it half way maxed out. Will update when maxed and running.

Very satisfied with the quality of the Victron product. Connects to blue tooth quickly. Easy to install.

I needed an upgrade and it seems to work well. its part of a system. I've been using PWM in the past so MPPT has been a improvement.

Excellent unit , not our first Victron solar charge controller. Solid build. Definitely would buy again. We also have a set up where we run two 100/30 units together. All our systems are for off grid cabins . 24v for us .

Easy setup. Works as advertised. Runs a bit hot. It has a good heatsink so I'm not worried about the electronics but you'll need to provide good air flow. The bluetooth connectivity is convenient and the app works well. I do wish that the app saved the data locally and let you display the graphs when not connected to the device however. The bluetooth range could also be improved. I have the controller connected to a battery in the same cabinet and I can connect to the battery's BMS just fine from the living room but not to the controller. All are minor issues but one star off for the lot of them.

After having a Renogy Rover melt on me (they warrantied it as defective), I decided to go with a quality product and am thankful I did. The Victron unit is much smaller than the Renogy and produces better power. For instance, I used the same two panels and changed the input from Renogy to Victron. The Renogy on average produces 10% less than the Victron measured through a shunt and application values. The app interface is also so much better and the ability to export a CSV is a huge benefit as I’m building a MySQL database of solar yield to weather patterns and battery voltage. I’m a data nerd so this was probably one of the features I was most excited about. It’s also fantastic that Victron has an open source software that can be run on a raspberry pi to add remote monitoring.
