Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 75V, 10 amp, 12/24-Volt

Received controller yesterday and installed yesterday. It works as described, very nice. Bluetooth works very nice, the available customizable functions are enough for my needs. For the money and what you get, i will never buy another $20 etc. budget controller again. This one is the 75/10 and i did not know the 75/15 was only a few dollars more or i would have bought that one, why not. I use these as battery maintainers on my autos, big boy toys etc., I have been through allot of $20 budget controller that i have no customizable functions, no more of that. I will buy a few of these i think. If i had to give a negative it would be the Bluetooth range you have to be pretty much right next to it, at least that's what i am finding. I have other Bluetooth devices that i get much farther ranges on.

The wiring terminals are of good quality, although I’d use ferrules. The case has the awesome Victon blue color and the main app works with this module as well, and is easy to use. The amount of data you get is super cool and useful. I have a 100 watt panel connected for battery charging purposes, and I’ve seen over 5Amps output, which is impressive. Overall it’s an awesome compact unit.

got this thing installed in my sedan/car. charges the car battery just fine. car interior reach +120F, but the unit works fine.

I have three Victron Energy solar charge controllers of different sizes. I love them all and personally think they are the best. They perform flawlessly and are extremely efficient. The controllers all have the same configuration interface per Bluetooth with the Victron Energy App on iPhone/Android. I can set up fully customized charging profiles easily and can see the performance at a glance. The controller is small and robust, weather proof and is a great value for its performance and price. I will say that if you attempt to get any support from Victron Energy, forget it. You are out of luck and have to go to the dealers for help. Please check who the dealer is before you buy so you have someplace to turn to for support if needed. Because of the support aspect, I give this controller 4 stars. I wish there was a better support system for customers.

I have two of these connected to lead-acid deep-cycle batteries. One drives a remote bird-house camera and one powers a pump in a bird bath. They were easy to set up and the instructions are clear. They have enormous programmability. The phone app is great for checking on the battery performance, solar power level, load, etc. There are a couple of features I wish it had. One is more pre-programmed battery types. They offer a few basic battery types and a custom program of gazillions of charging parameters for experts. I'm an electrical engineer and could get out the data sheet for my specific battery and program all the parameters, but what a hassle, and what if I make a mistake? It would be nice to have a few more standard lead-acid battery types in the menu. The unit has a streetlight function for turning on a light at night, but I want a general purpose timer that turns on the load in the day. That would be a small amount of software for Victron to add to the unit and the application. I want our birdbath to run only during the day. I could have used a smaller solar panel and smaller battery if this unit had a timer feature. This unit keeps a history of solar power generated and load power consumed that goes back at least a few weeks. I haven't looked to see how far back it goes, but it's interesting and useful to see how the panels are doing, or if the load is drawing unexpected power. It was also useful to see if my calculations were correct.

I installed this at our neighborhood HOA entrance to control a small solar/battery setup used to light our sign at night. I found the Bluetooth strong enough. I can easily talk to the controller 10 ft away. So easy with the app to check operation and change settings. Big game changer from the cheap pwm controller it replaced. So glad I upgraded to this MPPT controller which you really need for a solar application if you want to get the most from your panels. The streetlight setting and the load output made my application a breeze.

This Victron charge controller is a good choice for small projects such as keeping a vehicle or sump pump battery charged from a 25 Watt (or larger) solar panel. Ability to tailor parameters and monitor performance with a Bluetooth connection is a plus. The unit is dust and moisture resistant when mounted with the terminals facing down. As expected the MPPT buck/boost circuitry assures your battery gets the most possible charge given variable solar exposure. The Victron is more expensive than some, but is brand offers better than average quality and features. It makes sense to invest in a good quality controller to get maximum use and lifespan from your expensive batteries.

Solar is a great thing. Got sun? Free energy! But there is a learning curve to maximize your investment. Victron is one of the shining brands of solar energy, but top-brands don't always mean top-dollar. I was very happy to find this low-cost charge controller to upgrade my DIY power station to MPPT. Quick lesson: MPPT stands for Maximum Power Point Tracking. That's a neat bit of technology that squeezes out as much energy as possible from your solar panels. Must less expensive charge controllers (even if they SAY they're MPPT) are PWM, or Pulse Wave Modulation. Those devices work, but they do not have the extra efficiency to boost solar charging. In fact, MPPT devices like this Victron get you up to 25% more energy over a PWM charger. Back to the topic: This is indeed an MPPT solar charger, rated at 75 volts maximum, 10 amps maximum. You need to know what your solar panel(s) produce to know whether you can use this charger. It lacks a display, though small LED lights report basic charging functions: Float, Absorption, Bulk. And an intermittent flashing blue light lets you know Bluetooth is connected. Speaking of Bluetooth, yes, it's built-in to the device, you don't need a separate dongle. Download the Victron App, use the passkey included with the paperwork, and you have full access to the charger. You can't run many panels with this, probably no more than two, 100 watt panels in series would be best, though you could add three in series and still be within the 75/10 specifications. Check your panels to be sure. It's a great size for a DIY powerstation. A current pricing you could Frankenstein your own 500 watt pure sine-wave for less than $300. It includes a 20 amp standard blade fuse. I'd recommend have a few more on hand. Don't go lower than 15 amp. 20 amp is the device's sweet-spot. It does feature load ports, but no USB. While it's well built and great value, I do have two minor complaints... The wire outlets are really small. I had to double-crimp my ferrules to get them in. And as is the case with several small charge controllers, the openings to tighten the connections are small. I'm surprised these are flat-head screws, too. So if you don't have a small flat-head screwdriver, you'll need one before you can do anything with this. To be honest, Victron has higher voltage/amperage models for just a few dollars more. But if your needs are small and you don't see upgrading later, this will take care of you.

Exelente mppt para mi sistema aislado de energía.

Installation simple et paramétrage rapide en Bluetooth, très bon produit, je l'utilise pour charger une batterie LifePo4, fonctionne très bien

Pros: Works great for a small solar setup Phone app for setup and monitoring is amazing Easy connection Con: Wire terminals could be larger but work fine for wire size recommended
