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.

When I look at the specs, they all appear to be the same dimensions, 30A , 60A or 100A MPPT, so I thought I'd add the weight of the small unit, which was 248g, however the manual said 300.I'm not convinced/ can't comment at this time if it's an MPPT controller or a PWM, however I can say that the connectors worked well. The display isn't super bright, but it does track Ah in and out. In my case, my load is coming off the battery, so it's not tracking that, but still, that was why I went with this controller over the other similar ones at this price point - even if it's not MPPT.According to my measurements, it draws 22 mA when running in the daylight, although the manual calls is 10 mA.You can change your load on/off points so that at 11.5(max) it will shut off the connected load to save your battery and it will turn on again at 12.6 (max). At 12.3V a battery is 50% discharged - not accounting for the "load", so I would ideally set it to 12.0V to shut off my load and not turn it back on until the battery was at 12.9V - showing a reasonable charge based on my 120W panel. I didn't check the minimums, but at least 10.5 for the shutting off as that's the default. As far as max charge it starts at 14.2V, and will only go down as far as 13.7. I'm more afraid of cooking a battery than undercharging it, so I would've went to 13.4 or something. I don't mind putting an actual charger on it occasionally to top it right up - again I'm more concerned with battery health than anything, but I might be alone in that.Lastly, something I didn't realize about it is you can program your load to only come on during daylight hours, or to only stay on 1-15 hours after daylight ends. Or you can manually on/off, but you can't say turn a load on automatically at 7 pm and go to 3 am or anything. Still it could be a useful feature to some. Otherwise if you don't use these settings a quick button press changes you from on and off. The 30A controller allows 10A draw on the load side.

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.
