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

I have a small system with two 100 watt PV panels and a 1000 watt pure sine wave inverter. This charge controller allows me to squeeze out all the wattage out of the PV panels even on cloudy days. So far Ive seen a max of 175 watts from the two panels in direct sunlight and 24 - 135 watts on cloudy days... not bad. The build quality is exceptional, the plastic case is thick and heavy and the components are solid. I like the simple design. The only thing I dont like about the controller are the wire nuts and ports, they are rather small. You may have a problem connecting any wire gauge smaller than 10 to this controller. The Victron connect app provides useful information via Bluetooth but you need to be within a few feet of the controller to keep a stable connection. I will be ordering the Bluetooth battery shunt shortly and setting up a VE.Direct network to get better battery information as the controller only provides limited information on the battery charge state and voltage. I am finding that Victron is more like expensive Lego blocks if you want additional functionality you need to purchase more bolt-on components. Unfortunately most of their components are expensive but you get what you pay for and they make very good products.

I really like Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth). It really is doing everything for me. AAAAA+++++

Love this charger !!! Very easy installation and it works fantastic. The only complaint I have with it is the bluetooth capability. A large part of the reason I purchased this controller was so that I could monitor my charging from a mounted tablet on the wall using Victrons Bluetooth app. I can only mount the tablet about 10 feet away from the controller or it keeps losing Bluetooth connection. This seems to be a very common issue with these as well as most Victron products. I adjusted where I was mounting my tablet and it works well, just not where I had originally wanted it.

I got this to upgrade older pwm controllers and most specifically for the data monitoring software. The data monitoring on this thing is great and one of the best out there for a small product like this. The fact it keeps track of energy production and battery condition is great. BUT the load controls setting for the load output terminals has been a nightmare to configure or get working properly. I got two of these and with the new software both do the same issue. Under custom settings the the load is supposed to be driven on and off by the battery voltage. How ever I have had issues where the load terminals never turn or when they do it doesnt turn the load off and completely drains the battery. I know that most people or applications dont use the load terminals and it doesnt affect there system. Mine is for a water pump so the load control was part of the buying decision. For now I have resorted to a different control.

I had a 6 year old group 27 AGM battery in my truck which was starting to die. After connecting this battery and the new Victron charge controller the battery came back to life. The algorithm of bulk, absorption and float revived this battery at a point where I did not need to replace it by a new one. I had the charge controller connected to a single 100W solar panel and occasionally hoked it up. In about 3 weeks and around 15 charges the Victron device learned and applied sort of a recovery algorithm and raised the current charge rescuing the battery. Now when I turn on the truck in the morning it feels like the battery is brand new and the battery voltage stays at a constant 12.6V every morning.

The Victron 100/20amp controller installed and started without problems. I was able to use the VictronConnect app to look at the status of the system and configure the charging profile for my 100 ah hybrid gel battery. The controller powers all loads until PV capacity is exceeded then adds in battery power as needed. No need to remove battery for charging ever.

I installed two of these solar charge controllers about seven days ago. They seem to be working great. I also installed Victrons smart phone application and was able to promptly update the firmware and monitor their measurements via Bluetooth on my phone. I would definitely buy these again.

Installed this as an upgrade to the PWM charge controller that came with my travel trailer. Noticeable decrease in charging times (increased efficiency). This is paired with 380W of panels and two Battle Born 100AH Lithium batteries. I would recommend this for a new install, or as an upgrade.

This is my second one of these. The Bluetooth based information from the unit raised my solar expertise up a level. Do make sure to change the Bluetooth pin as this is an internet of things device. Voltage does change curiously, but that’s the built in temperature adjustment. The load circuit does get tripped occasionally, I presume from some of the cheaper power outlets I used. It isn’t clear how to reset when this happens, I just disconnect the positive load and connect it directly to the battery, then switch back after a awhile. I’ve had that happen 2-3 times a year on my first unit and it is still working good. This is a lead acid designed controller but is fully programmable and includes agm and lithium presets.

I own many Victron charge controllers. I like these the best because: 1) They actually work with most battery banks -- 12/24/36/48, Yes 36v works. 2) Unlike the bigger more expensive units, the fuse is external and replaceable 3) You can buy 6 of these for the price of a 250/100 controller 4) If you have one big charge controller and it fails. Your whole system is dead. There is strength in numbers. Unless you NEED big high voltage strings, these are a better option in my humble opinion.
