Victron EnergySmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 100V, 20 amp, 48-Volt

Been using for about 6 months now. Having been a person who cobbles together cheap stuff usually... this was SO worth the investment. It just works... and it works great. The app is fantastic too, without requiring an account or internet connection.This product made me start buying into the whole Victron ecosystem. Being an power supply electrical engineer myself, I did open up their products and you absolutely get what you pay for... attention to detail and reliability.My one and only gripe about this MPPT controller is... on a 48V system, the output is limit to something like an amp, which is mostly usless. I'm not sure why they couldn't spec the components to be rated for more... but like they say you can use the output to run a relay or something. Little annoying but still would absolutely recommend this product to anyone.

I recently purchased two *Victron 100/20 Smart solar charge controllers for my (off-grid/on-grid) solar ranch project. These controllers are very versatile and compatible with any 12v, 24v, or 48-volt system and are rated up to 100 volts max / 20 amps max. Currently, these controllers are managing two 480-watt 24-volt solar arrays and two 24-volt x 400Ah battery banks. I plan to expand to a 48-volt system soon using the same controllers. The Bluetooth function is very handy for changing settings and monitoring your system. I didn't see a real need for a display screen on the unit itself (unlike a few reviews I've read) since you can carry the display screen with you using the phone app.I'm sold on *VICTRON*. Spend a couple more dollars and get the best. Five ***** Stars!

I have 3 Kyocera 140 watt PV modules in series so needed a MPPT charge controller capable of switching that HV input to charge a 24 VDC battery to replace the BZ products one which failed.The unit works great, but I wish it came in an enclosure capable of accomodating the need for conduit... which is a NEC code requirement. I kludged some wire wrap over the connections which is hacky at best.

Excelente

I have many Victron components and as always they work flawlessly. This does great with my solar panels on my RV. Functions perfect, bluetooth adds so much. Controls are easy, and the controllers is perfect.

The second one I received worked as it should. The first one I received the load would not turn on. Note load off seems to work instantly but load 'always on' doesn't seem to turn on the load instantly for some reason. I will need to do more testing. It can take 2 minutes for the load to come on when first powered up.

We would recommend this to everyone! We live on a sailboat and it works amazingly.

This solar charge controller is my go-to controller for my solar generator builds. I use a 12 volt system and these are Bluetooth and connectivity is is positive. These controllers all well built small in size and the connections are easy to locate. I have purchased at least six of these for my solar generators that I have built and I have had no issues with installation and connectivity. Anyone that is building a solar generator will be happy with this product because the app software provides information in regards to watt hours are being used and All battery functions are listed on the app. There are no negatives in my opinion with the solar charge controller.
