LiTime 60A MPPT Solar Charge Controller (No Build-in Bluetooth), 12V/24V/36V/48V Auto, Max PV Input 200VDC LCD Display Solar Panel Regulator for LiFePO4/Lead-acid Battery

I bought three of them..I rebuilt my system i needed more than 150 volts rating on charge controler these are perfect 200v for my solar PV. Simple to use and very happy with performance.

Only had it a month, But works better than the cheap ones. 48Volt system 1650 watts, Pushing 142-145 volts on a 19' degree Day, Only thing that would be nice is a Bluetooth or Wifi. The fan keeps it nice and Cool, if you can handle a little fan noise when it is working Hard, Then you might buy a cheap one (But they get Hot and Trip out) above 120 V. FYI)

No problems. Screen hard to see even inside box.

Nicely manufactured with the right accessories from a well known battery manufacturer.

Excellent unit for the price - I was surprised by how well it is engineered. Once I found the right manual on the manufacturer's website, configuration was a breeze. I really appreciate being able to scroll through all the important charge/discharge measurements, with a single button. Efficiency appears to be as high as advertised, from back of a napkin calculations. As far as negatives - I wish the cooling fan was a little quieter.

Instructions are a nightmare, but once you get it, it seems to work well. I just installed literally today. UPDATE: This charge controller is Junk. It has settings for the voltages listed, however the custom settings aren't adjustable and no matter what settings you use. Be it Li, or FePo4, or custom settings, none of them fully top off the batteries. I have brand new 200ah worth of Lithium batteries at 24v, 1320w of solar, and with full sun I have yet to see above 28 amps, and yet to see 40% of my batteries last longer than 2 hours on a 4 amp load, unless I run a battery charger to top them off after the sun goes down. I have changed everything but this charge controller since I bought it and still having the same issues. I bought this peice of crap to save on generator fuel, and I have to run the generator just as much to top the batteries off.

compared to a few I've tried, this charger is great. User interface is nicely designed that makes good sense, intuitive. Easy setup, started working immediately. Efficiency also very good.

This MPPT is workig great to help manage the solar power I am capturing from 2 x 400w solar panels. Makes sure my 2 x LiFe batteries are getting charged and maintained at the proper level without being drained. Then managing the power to the inverter to power my 120VAC needs at my house.
