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 .

Why did you pick this product vs others?: Always in favor of the best product money can buy. Ease of installation: Install the wiring as it is labeled Value for money: After multiple research of products, I love the ability to communicate multiple devices to one system. Bluetooth connectivity: Ease of use for setup and monitoring as well as updates.

I wish the app was wifi instead of bluetooth. I didn't see a wifi unit when I ordered. Getting tired of heading out to my off grid shop to check on this. Especially now that temps in the upper midwest are sub-zero. Unit itself seems to be doing its job. Lets me series up my panels to run higher voltage with much less current to the battery system. The daily totals in the app were an interesting find.
