[Upgraded] 30A Solar Charge Controller, 12V/ 24V Solar Panel Regulator with Adjustable LCD Display Dual USB Port Timer Setting PWM Auto Parameter

Works great hooked to a 100 watt panel and 100ah lithium battery

Second one purchased, used in camper build feeding 200W solar into 200Ah Li batteries. Seems stable, runs cool, no gremlins so far, EXCEPT:NOTE it is shipped set up for 24V output (mine was anyway), you will need to **immediately** reprogram for 13V output or you could overload your 12 V system.This is not a complaint, just informational. I like it and bought a spare.

It works, works great but the directions or the tiny little instructions that come with it are worthless and not in order. You can figure it out yourself better. The voltages don't match with my Fluke VOM Meter but not that far off. I have it set up with 2 each 100 watt solar panels, 2 each 180 amp deep cycle batteries in a 12 volt parallel and charge 2 each 1000 watt solar generators, the shut down low voltage is 10.7 and 14.4 at high. It doesn't like to do both solar input to batteries and output to load at the same time causing it to jump around between low and high limit volts but you can set it to do each one separately where it works great. The 2 USB's work well and put out 2 volts. It works just as good as the $200 ones except it's sensitive , for the price it's well worth it.

I have no idea what this is. It says it's PWM, but not sure. It says it can support 30A but the terminals are undersized. It says it can charge a Lithium battery but there is no indication that the battery is actually be charged because there is no way to show Amps coming in. This controller lacks all the important features you need like being able to adjust your array if your Amps are to low or determine you have a wiring problem because your Amps are too low or realize your battery is not charging because you hooked up to many panels in series. That's right, no one will tell you but good luck with panels in series with this controller and given how bad quality the terminals and soldering I'm not sure I would recommend this.

Works perfectly

Really hard to figure out how to use these. The "manual" isn't really clear. Need to do more testing. Had it shutting down the input source when the battery was pulling an amp to 1.5 amps of charge.

Super easy connections. Made a recharge solar box used it as the control feature.

Exactly as described works great so far.
