Using Suggestion:
1. This controller is for 12V/24V. When installing for the first time, please make sure the battery has sufficient voltage so that the controller can recognize the normal battery type.
2. Install the controller to the battery as close as possible to avoid voltage dropping caused by over long wires and affect normal voltage judgment.
3. This controller is only applicable to various lead-acid batteries.Do not use other batteries (including lithium batteries, nickel-metal hydride batteries, etc.).
4. This controller can only use the photovoltaic panel as a charging source. Do not use a DC or other power source as a charging source.
5. The controller will heat up when it is running. Please be careful to install the controller on a flat, well-ventilated place.

    Works like a charm!

    This is my 4th solar installation, and I decided to give this one a shot because of the 2 USB ports right I wired the system up with 8 gauge wire and the controller does accept an AWG 8 wire! I did make a custom wodden support panel so the wires are hidden behind the panel. It fired right up and works perfect. We really like the 2 USB ports so we can charge it. So far so good!

    Worth buying.

    I had to buy a new solar charge controller in a hurry and this one seemed to fit the bill. Previously had a name.brand unit and it failed within six months. This one is holding up great and has as added bonus the usb charging ports. By the way they will drain you cell phone down at night time if not unplugged. Great unit. Ordered a spare to keep in the trailer as a back up.

    Worked for a while.

    Device worked for 24 hours. Clock set to auto, battery showing no charge and no output. PV is charging. Actual battery voltage is at 12.2 volts. I hope they read this because I need help. I am ten days outside of my return window.
