MPPT SOLAR
<br />CHARGE CONTROLLER
<br />1. SAFETY
<br />Full
<br />consideration to the safety of persons and property has been given when
<br />designing the products. However the incorrect connection may cause the system
<br />breakdown or even safety accident. For your safety and benefits, the following
<br />rules must be complied during the operation.
<br />. Installation
<br />of this product shall be tinder the guidance of the professionals in this field.
<br />. Prevent this controller from water, humidity and insects, to avoid
<br />short-circuit.
<br />. Keep children and incapable persons away from the
<br />controller
<br />. Keep the controller away from electrical heater, heating machine
<br />and other high temperature electrical appliances; avoid the controller suffering
<br />from insulation directly.
<br />. Please check the rated voltage of solar panel,
<br />battery, and loads before connection. 12V rated voltage is 12V, 24V rated
<br />voltage is 24V, 48V rated voltage is 48V.
<br />. Make sure connections between
<br />positive and negative poles of Solar panels, Battery and Loads are correct.
<br />. The diameter of connecting cable must be matched with the requirements of
<br />the current. Do not use thinner diameter cable, the thinner diameter. The larger
<br />resistance, this will cause higher temperature and output power decreasing.
<br />. The total rated current of solar panel and loads must be smaller than the
<br />rated current of the controller.
<br />. Components of system must be correctly
<br />and firmly connected. Prevent the terminals from oxidation and moldy, to avoid
<br />connection trouble.
<br />
<br />Function:
<br />. Always keep
<br />the battery on fill voltage condition.
<br />. Prevent the battery from
<br />over-charging.
<br />. Prevent the battery from over-discharging.
<br />. Prevent
<br />the battery from reverse charging to solar panels during nights.
<br />. Reverse
<br />Polarity Protection for Battery
<br />. Reverse Polarity Protection for Solar
<br />Panels
<br />. When the battery voltage is low, the controller will automatically
<br />cut off the load from the system. If the voltage of battery is back to normal
<br />and the load will restart working.
<br />. Thunder protection
<br />. According to
<br />the battery voltage grade, the controller can automatically set charge-off
<br />voltage, the load-off voltage, the load- restore voltage. (The parameter is
<br />default under 25
<br /> 
<br />condition,
<br />locked by the CPU procedure, cannot adjust.)
<br />. The
<br />controller will automatically compensate the temperature of the charging voltage
<br />according to the changes of ambient
<br />temperature.
<br />Warning:
<br />Before
<br />connecting to the solar panel, please connect the controller to the battery; do
<br />not use solar panel supply power to the loads directly.
<br />Notes:
<br />Do not use
<br />lamplight to charge the solar panel (lamplight is too weak to charge)
<br />DC
<br />power source to replace the solar panel will cause troubles to
<br />controller.
<br />Choose the
<br />suitable wire which diameter should not be too small, please refer to the
<br />parameter.
<br />3. INDICATE
<br />LIGHT AND BUTTON
<br />. When Red LED
<br />(CHARGE) is on, battery is charged up strongly; When Red LED is flickering,
<br />battery is MPPT charged up in constant voltage; when Red LED is oft charge
<br />off
<br />. When Green LED (LOAD) is on, loads are working; when Green LED (LOAD)
<br />is off, loads stop working.
<br />. Three Color-changing LED (BATTERY), When light
<br />is red, it indicates low voltage, green indicate battery full charged, orange
<br />indicate normal status.
