30A MPPT Solar Charge Controller, 12V/ 24V Solar Panel Battery Intelligent Regulator with Dual USB Port, LCD Display and Timer Setting ON/Off Hours

This 60 Amp MPPT solar charger is working great at managing my small array of 8 x 100 watt panels charging 4 x 100Ahr LiFePO4 batteries. I see some negative reviews and wonder if proper setup was done. The owner manual says maximum input voltage from the panel is 23 volts (many panel will exceed this voltage, so check panel voltage ) and there is a specific setting for charging LiFePO4 batteries. See my pictures. I had this unit online for less than a month. It does get warm mid-day when there is about 35 Amps coming in from the panels. I will update with longevity.

The unit is very smart with many settings for nighttime only or daytime usage , 12 or 24 volt systems with automatic detection of either. Works with 12 volt panels right up to 30 v and has been error free for 6+ months. It even gives you a rough idea of how much power came in and went out over the time its been powered on. Be sure to select your battery type in the appropriate menu. Can be combined with another dissimilar battery pack via another charge controller or a timer to further control usage times. A car terminal block may be used for distribution. There may be a puff of smoke upon first connection , this is just the factory oils burning off. The 100A unit pictured left is having used battery troubles and thus is currently blanked. April 2025 Update . 18 months , they still work but i have noticed neither screen will show anything anymore , the internals are still just fine but no display makes for tough understanding of the overall system. Some voltage protection for the screens would be prudent to extend the safe life of the screen. That's an internal device issue but also still functional without display. pleasantly surprised

Fantastic product

Fantastic and robust. Highly recommend

This controller is misleading in it's description and is a complete piece of crap! The title makes you believe this is a MPPT controller -- "60A MPPT Solar Charge Controller". However, it appears that the name of the company is "MPPT Solar". It claims to use "MPPT technology", but further in the listing it states "and has fully 3-stage PWM charge management". What a bait-and-switch! Worse, this thing doesn't live up to the specs it lists. I hooked this up to a single 375 panel that outputs 40v max amperature ~10amp). As soon as I connect the panel the screen on the controller goes blank. I debugged the hell out of this thing and at the end of the day, it's just a crappy product. I'm returning this and picking up something from a more reputable brand.
