12 Volt 30 Amp Digital Solar Charge Controller
Installation & Operation Manual
This 30Amp charge controller is designed to protect your 12Volt Lead-acid or Gel-cell battery
from being overcharge by solar panel, which prevents discharge of battery during nighttime.
This controller reduces overall system maintenance and prolongs your battery life. It will
continuously display the charging current or battery voltage in charging proceeding from
LCD digital meter; also automatically indicate your battery condition from LED bar-graph.
This controller is design to work with all kinds of 12 Volt solar panels for indoor use.
