Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth)

good little controller. The terminals are very flimsy & cant get 8 awg or even 10awg wire in without stripping cable stains down! Connection problems they come loose or fall out. It wont charge of they are loose! They are to close together & might short out… make sure u use strain reliefs & zipties. After tgat i was able to get it to work…Manual to small to read & obtuse! No customer support ur on your own here!

Great solid case, the efficiency is great and I really liked the bluetooth/wireless networking. This really helps overcome some of the documentation challenges with a Victron product. The ability of this device to network with the BMS product is great. Unfortunately the whole of the Victron line of products are not up to this same level of integration just yet, so dont expect the inverter/charger line of products to integrate with this system.

Used to replace a pwm controller on my 100w portable system. HUGE improvement on efficiency for my rv charging.

This little solar charger is packed with Bluetooth built in, the range is somewhat limited but Ive NO issue with that. The electrical ports could use better little screws for lack of knowing the right name for it. Or better idea, package in some wire leads that fit it well. For the size of charger I got(75/15) the sizing is great. Very solid housing, with corner holes for mounting.

Spend a few dollars extra and get the best. In my case the small size and feature set made it the only logical choice for my boat. The bluetooth connection feature(s) via smart phone is worth every penny, you can change LifoPO4 to lead acid settings in 30 seconds. I can monitor my battery bank from the house, If you are going to hook up 3 or more panels in series you may want to get the 100V version for about $20 more. Cons: I have read these units run a little warm. That is because they have the best MPPT controllers in the business and actually do create the most watts from the array, Bluetooth network probably sucks some power to maintain, but we are talking minimal amounts. The screw connecters for the wires are small, and I couldnt put a #10 stranded marine wire in them. Customer support is funky, but the distributor that sold it to me called me on phone within an hour. Documentation can be confusing at times

I had a Victron 75/15 MPPT controller that worked well but failed after 3 years. I replaced it with this, and I get more out of my 300 watt panel than I ever have before. It also has pre-sets for LiFePO4 batteries that I migrated to from AGMs in my Sprinter van. Works perfectly.

I use this to charge my battery with solar. With the Bluetooth capability. Now I can monitor the status of my second battery.

The Victron 100 20 MPPT controller delivers peformance as effortlessly and efficiently as it delivers energy. This unit was connected to two 105 A-hr lead acid deep cycle batteries for storage, two 120 W Photovoltaic panels for energy capture, powering a load composed of a Dometic 95DZ dual zone fridge freezer. For the test a grocery load was simulated with two 1 gallon jugs of tap water and two ice cube trays of water to make ice. The test was begun late in afternoon on Saturday and concluded early evening on Sunday. The Victron supplied energy throughout the entire process and smoothley and effortlessly transitioned from solar power to battery. As the sun came up I was able to monitor panel voltage in real time, and began to see it slowly offset battery power, until the batteries began to charge and all power for the Dometic was supplied by panels. The test was a complete success and demonstrated to me the need to expand the system by one battery and one pannel to 345 A-hr, and 360 W solar. The Victron did extremely well and was only slightly warm at highest load condition. Thank you!

I highly recommend this product. Just returned from a 63 day camping trip during which the Victron 20 Amp controller worked flawlessly. 60 of our 63 day trip were without shore power and relied on our 100 watt solar panel. While I have a generator, there was never a need to use it to charge our batteries. The Victron controller was part of an upgrade I did that replaced a cheap PWM controller, moved the controller from the solar panel to the battery box, and added 8 gauge wires from the controller to the batteries. The Victron controller charged my two group 27/66 amp hour batteries more quickly and more deeply than the PWM controller. My energy into the batteries from my solar panel now always exceeds my energy out (I track cumulative watt/hours). I could also run my fantastic fan during the day and my batteries would still receive an excellent charge. These MPPT controllers charger more rapidly than PWM by converting excess volts to additional amps. The Victron controller consistently stepped up the amps coming from the solar panel by as much as .7 amps. Excellent product!

This is a true MPPT,should of gotten this a long time ago, battery even charging on a cloudy day
