    Excellent product which I have purchased and used on previous occasions. The unit comes well packed for shipping and in it’s own box. In the box is the charge controller and a manual which gives installation and configuration instructions in English and Chinese. A diagram of the controller gives clear instructions on how the solar panel input, battery and load output are connected via paired (plus/minus) screw terminals. The controller can be configured via the display and selection buttons. The display is large enough to be read without glasses for most however it is not illuminated so will require an external light source to be read in a dark environment. The controller supports the display of battery voltage, solar panel charge current, load discharge current, accumulated discharge power and accumulated charging power. The controller supports the configuration of battery high voltage disconnection, low voltage disconnection, low voltage re-connection and a load working mode which allows the user to turn the output load off ‘x’ hours after sunset or run the load 24 hours a day. As far as battery types the controller is quite flexible as the high voltage disconnection and low voltage disconnection and fully configurable within the bounds of your system (that is 12 volts or 24 volts). The controller ordered was 100 amp model. The manual for this controller stipulates that it can charge 60 amp to the battery and 30 amp to the load at the same time which only adds up to 90 amps but I guess there must be some leeway for internal currents. Conveniently the controller comes with two USB outputs. These are low amperage outputs. One important thing to remember is to make sure you connect the battery to the controller before solar input and load output and make sure that the battery / batteries you are connecting are reasonably charged. The reason for this is that the controller will sense the battery voltage and set itself up for a 12 volt or 24 volt system.

    I got the controllers on time. They're whole, with no broken or scratched. I haven't installed it yet, so I hope it's all working. I wasn't taxed. For now, I recommend a salesperson.

    This is not a MPPT charger as other people have stated. it's a PWM, see attached pictures, has no coils or transformers inside to adapt impedance from the solar pannel to batteries. interesting itt has two barrel connectors that are not documented.

    good price for a standard solar controller, but this is not a MPPT controller.

    excellent product, fast shipping, the only problem is that female connector is badly welded, it's a bit crooked...

    Thank you for the quick and attentive shipping. The product is as advertised and does not see quality, I haven't run it yet.
