    Attention:
    1. ALWAYS connect battery first !! Make sure enough batteries’ voltage let controller recognize the right system voltage. NEVER connect the solar panel array to the controller without a battery. The disassembly sequence is contrary to the wiring order.
    2. DO NOT connect any Inverter/ wind/ Alternator or Charger into the charge controller !! Please connect the Inverter directly to the battery.
    3. Ensure solar input voltage higher 3V or more than batteries’ voltage and total input power in the range. If input power is too low for max input power, it may be appears to have been discontinued, the charging current almost be zero when controller is floating charge.
    4. The charging indicator is on and off, and the charging current is off and on. This situation generally occurs on cloudy days or in the evening when the light is insufficient, which is a normal phenomenon.
    5. When the controller is buzzing, it is because the fan is trying to dissipate heat. Please wait patiently.
    6. DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating. Remove all clutter around the controller to reduce interference and make sure there is enough space for heat dissipation. ( leaving a space of approx. 20cm )
    7. Ensure all connections going into and from the controller are tight. DO NOT let the positive (+) and negative (-) terminals of the battery touch each other.

    Solid unit, well built, nicely designed

    So far I like everything I see here. It's a well built, solid unit. Construction wise, I'd have made the fuses easier to access, but it just makes you want to really be sure you keep your current under the limit :) The manual leaves something to be desired. You kind of have to hunt for the code to access the parameter-setting screens, which they make harder and say "the parameter settings must be operated by qualified technicians"... but in reality, especially since they set the battery default to AGM, the battery parameters are the first thing you need to change if you have LiFePO4 or other batteries to use on your system, so ... hint: The "password" is three down arrows, then three up arrows, then enter.

    There are settings for just about everything, time, date, the beeping keys (which I immediately turned off), etc. But once it's set up it's good. I'm putting this on a small 1kW system with a few 100 Ah LiFePO4 batteries and I should never see the full 40 A inrush given the relatively light loads I use and the fact that they rarely discharge over a full day of use to below 50%.

    If I encounter any unexpected behaviors, I'll return to edit the review accordingly. Right now, I'm expecting this to be a good unit, and a price point (around 75 USD at the time I purchased) that made it attractive against higher cost units like Victron. I've got about a dozen charge controllers I've run up and tested so far, most are OK, but I expect this one might be a bit better overall. Time will tell.

    40amp It works

    Wanted to offset my telecom and office as it runs 24/7. As well as have it powered in the event of power outages. Well it does the job 800 watts is more than enough however the system is up for 500watts.

    it works as it should here is hoping it last at least 5 years.
