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.

    Must have for auto repair, handyman work or hobbyist

    Great for a do it yourselfer. If you do auto repair work or handy work around the house or maybe for hobby applications, you will find yourself needing one of these grommets. And with all the sizes included in the box, there has to be one that will fit the situation.

    Easy to read the panel

    I got this controller as I am new to the solar power panels. I wanted to make sure to protect my battery and lights as I connected this to my RV. Its easy to read the panel and easier to use than the electric box on my RV. Easy to follow instructions.
