The product can automatically manage the working of solar panel and battery in solar system. It is easy to set up and operate. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically (LCD will be unavailable at the same time).

Change the default setting of solar controller, requires: 1. Disconnect the solar panel 2. ensure the remain voltage of battery no less than 12V

Note: <1>Avoid water, direct sunlight exposure, dusts(It must stay in cool and well-ventilated place to prevent from overheating)

<2> the regulator is only suitable for lead acid batteries:OPEN, AGM, GEL, not for nickel hydride, lithium, ions, or other batteries.

<3>Make sure your battery has enough voltage for it need to detect voltage and resistance from the battery prior to charging.

<4>Indoor use only: the working temperature of this controller is -35°C to +60°C, during hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation.

<5>When the battery voltage is too low, the controller will stop output(≦ 8V, controller turn off itself, LCD is blank,≦ 10.7V, 12V output ports are not available); after the solar panels charging, the battery will return to 12.6V. It is a natural to output(All values × 2 when using 24V system).
