LiTime 30 Amp MPPT 12V/24V/Auto DC Input Solar Charge Controller Build-in Bluetooth Module, Parameter Adjustable LCD Display LED Indicators Solar Panel

Much larger than your typical controller but very well made and looks great as well. Simple to understand and the digital display is easy to read. The Bluetooth app is a nice feature so you can keep tabs on the progress without having to go outside and check on it. MPPT does a great job with the charging process. After trying it out for a few weeks, I bought a 2nd one for my remote cabin's solar system. Manufacturer customer service was great when I inquired about other products.

LiTime really make a good product, this is our second unit to purchase and so far, all is working good.

Great product, Easy to install, solid build quality, and the display is very helpful.

I upgraded the battery in my nearly 40-year-old solar battery system at my off-grid cabin from lead-acid to LiFePO4, having gotten tired of replacing the lead-acid batteries every three to four years. With the change in battery type I also had to change the charge controller. I'll spare the details of a few other controllers I tried and finally bought what I should have in the first place, this LiTime 30A MPPT charge controller. This controller was easy to install and configure. The Bluetooth interface, which other suppliers offer as an option and charge extra for, was included and that was an added bonus for collecting data on the use and performance of my system. The companion free app installed easily on my Android tablet and is intuitive to use, though there are a few humorous "Chinglish" messages that appear. e.g. "Disconnected successed" comes up when you close out of the interface for the controller. The attached photos are of the controller installed in the load center of my system and a screen shot from the Bluetooth app on my tablet at the end of the season just before I shut everything down to close up for the winter. The discharge amp hours are not entirely accurate because I do not run the entire load of my cabin through the controller, that comes directly off the battery. I have a composting toilet with electric fans which I operate through the controller when we are away so the controller will shut those down if there would be some failure in the solar array or a very extended stretch of bad weather that would prevent the battery from charging enough. This controller has made my system almost completely hands-off in terms of day-to-day operation. With lead-acid batteries, especially late in the season, I had to constantly monitor the battery voltage and charge state because the reduced full sun time on my array at that time of year. This controller and the LiFePO4 battery just worked.

This large well built controller works great with solar panels on my truck. I like the load terminals as the load can be monitored and turned on & off via a button or the bluetooth app. The app is workable, but forgets its pairing when shutdown, keeps asking to pop up when minimized & there are places they use dark gray on black text which is hard to read in bright areas.

This is a very sturdy and well-built controller. However, the product manual does not define the various battery types. They have shut down the tech department without any explanation. There is no way to find out what the various error codes mean.

Returned item due to physical size. Original intent was to use this with field deployable solar panels and lithium batteries. This MTTP charger selected was my first choice, but I had to settle for a PWM type instead. MTTP chargers appear to be large in physical size and best suited for permanent or semi permanent large installations I would purchase this Solar Charge Controller again but for a large scale installation. Good product.

This controller was so easy to set up , I accidentally hooked up the solar leads up in the reverse and it let me know without causing any problems after that it took maybe 2 minutes to set up . very happy so far it is charging great with 2 lifepo4 batteries it automatically set it's self for lithium.

Matched this MPPT up with my LiTime batteries and it works great. Overall construction seem good although the buttons feel a little cheap. App works fantastic for monitoring all the stats and allows me to turn on the load without diving into the cabinet where it is mounted. You do have to be fairly close to connect the bluetooth but hasn't been an issue for me. Was similar or cheaper than some other options and I had no worries about any compatibility as it is LiTime same as my batteries. Would definitely buy again or recommend.

Pas installer encore mais semble de très bonne qualité à suivre...

Bluetooth functionality is awesome
