Victron EnergySmartSolar MPPT Tr Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 150V, 70 amp, 12/24/36/48-Volt

This is a replacement for a blue sky charge controller i was using in my RV. This thing is built like a tank and very heavy duty. It was very easy to install and works great for over a month so far. The Bluetooth and corresponding app are awesome to be able to check my solar history from my phone and i also bought the plug in meter so i can also see exactly what’s happening at a glance. I liked this so much that i bought 2 more for my solar powered work trailer. My only regret is not having upgraded to this sooner.

It has a functional and useful float mode. Very reliable. Easy to use interface.

Victron chargers are quality products. I have half a dozen of various sizes running off grid sites throughout the valley and they all just work. The Bluetooth makes checking their statuses very easy.

Everything made my Victron has been excellent. Their products have worked very well in my RV electrical system and when it came time to add solar panels to my RV, Victron was the only one I looked at. This has VE.DIRECT port on it so I was able to purchase that cable and integrate it into my Cerbo GX device to get a full picture of all incoming and outgoing power. Very versatile, easy to install, configure, and update firmware via the Bluetooth. Highly recommend.

Very efficient unit it will track the power of the panels to get the most out of them. I like the unit so much I have three off them.

I have an Aims 3k inverter charger and had EP Ever solar charge controllers. The EP Ever's would send a voltage spike to the inverter when the solar charge controllers finished the charge cycle which put the Aims inverter into a perm fault, requiring the inverter to be power cycled.The new Victron charge controller doesn't do the voltage spike anymore.Anyone want three EP Ever 40 amp solar charge controllers?

When I opened the package this charger controller looked and felt like a sturdy and quality product. When I connected it however there was absolutely no charge going to the batteries despite the controller getting input voltage from the solar panels. After days of troubleshooting and frustration I discovered that the black jumper wire was loose. Tightened that screws and the controller started working like it should. Been working great since. The Bluetooth connectivity is an amazing feature. Being able to get the readings from an app is amazing especially the 30 day report which lets you keep track and compare the daily performance of the solar system. On good days I get over 2KW from 2 x 300 watt (total 600 watts) solar panels. It also tells you how long of each stage (bulk, adsorption, float etc) daily. I have Battleborn lithium batteries and was able to program the parameters right from my phone. Pretty convenient to connect and monitor the controller from inside your house. Only downside is everything you open the app it has to reconnect. It’s pricey but worth it. Victron is a reliable and quality brand.

without really combing through the docs it's not super clear how fat your copper can be that you connect to your Tr terminals with these. with the Pv in you're usually good with something like 8awg if you're pushing 50+ volts of solar, the smaller wires are fine in that case because you're moving juice with voltage and less so with current. However, once you're dumping, say, ~2000 watts worth of 24v current to your batteries - YOU CAN AND SHOULD USE 2 AWG TO BATTERIES. 48v may be okay but if your system is under 36v don't even play with it, size as high as possible out the gate.... and yes I'm writing this because after about 1.5 years of ownership i have nearly melted a few things arriving at this conclusion.with all that said it's notable that this unit will detect an overheating connection at it's own terminals and shut off the output.above all, as per usual: just RTFM; READ THE MANUAL.
