1. Security
The factors referring to body and property security have been considered
during designed the products. But incorrect connection will cause to
breakdown. For your security, please do everything according to the
following regulation.
•Please contact the local agent before installation, which should be
guided by professional
•Prevent any liquid from spattering on controller. Do not clean the
controller with wet cloth
•Keep children and incapacity person away from controller
•Keep controller away from electrical heater, warmer and other source of
heat; avoid controller under Sun.
•Please check the rated voltage of solar panel, battery, and loads
before connection. Their rated voltages all should be 12V (or 24V).
•Pay more attention to connect the positive and negative pole among
Solar panels, Battery and Loads correctly..
•The diameter of connecting cable could not be smaller, which should be
suited to loads.
•The total rated current of solar panel and loads are kept lower than
controller’s rated current.
•Tight and good connection among components.
•Connecting wired battery positive and negative poles directly is
prohibited.
2.Feature
CMP (16A-24A) solar charge controller
is controlled by CPU, According to the voltage of battery; controller
will adjust the charge current and decide if to supply the loads
electricity. The following is the detailed performance:
•Generally keep the battery on full voltage condition.
•Prevent the battery from over-charging.
•Prevent the battery from over-discharging.
•Prevent supplying electricity from the battery to solar panels during
nights.
•Reverse Polarity Protection for Battery
•Reverse Polarity Protection for Solar panels
•When the current of load exceeds the rated one of controller, the
controller will turn into the self-protection state and is automatically
locked up, the screen shows “Overload”.
•Short Circuit happens; The Controller will turn into the
self-protection state and is locked up, the screen show “Short circuit”.
•Low voltage happens to battery, the controller will automatically
separate loads from system. When the voltage of battery goes up, the
loads will automatically restart to work.
•Protection from the lightning strike
•When Controller is normally working, the LCD Screen will show New
Charging Current (a dash“-”before the numeral), Discharging Current and
Voltage of battery every 5 seconds.
•Controller is always counting Charging Current Hours and Discharging
Current Hours of the Battery
•When controller start up, according to the voltage level of battery,
Controller will self-setup the Charging-off voltage, the Load-off
voltage, the Load-on voltage. These datum is tacitly approved under the
standard environment temperature 25℃.
•According to varies system temperature, the controller will
automatically compensate the temperature of the charging voltage.
•Users could setup the Charge-on or off voltage, the load-off voltage,
the Load-on voltage, etc, according to their requirements.
•To prevent battery from over discharging, Controller will automatically
control the lowest Load-off voltage of the load, which is no less than
10V (as per 12V battery) or 20V (as per 24V battery). If voltage of the
battery is less than 10V (or 20V), the button “-” will stop working.
•To recover its defaults, please keep pressing down the button “Menu”
for over 5 seconds.
3. Connection
As form
•Connect “+” and “-” poles of battery with the correct ports on the
controller (the third and fourth ports from the left).
•Connect “+” and “-”poles of solar panel with the correct ports on the
controller (the first and second ports from the left).
•Connect “+” and “-” poles of load with the correct ports on the
controller (the fifth and sixth ports from the left).
Attention!
•Correctly connect the electrodes of solar panels, battery and loads!
•Choose the proper cable according to the current of the loads; the
diameter could not be smaller. The cable 4m㎡ minimum is suggested!

5. Fix the breakdown
•phenomenon：Green light goes out, the loads stops
working, and LCD Screen shows Battery low
Reason：Low voltage of battery
Solution：Charge up the battery or change the battery
•phenomenon：Green light goes out, the
loads stops working, and LCD shows Over load
Reason：Overload
Solution： Reduce the quantity of loads and then press Button Reset
•Phenomenon：Green light goes out, the
loads stops working, and LCD Screen shows Short circuit
Reason：Short circuit is happening to loads.
Solution：Disconnecting the malfunction and then press the button
Reset
•Phenomenon：Green LED is light
Loads are normally working
•Phenomenon：Red LED is light
Battery is charged up rapidly
•Reason：Red LED is flickering
Battery is in constant voltage (or floating) charged up
•Phenomenon：Red LED goes out
Reason：Charge-off of battery
Solution：This is the common phenomenon during nights. If it is so
during days, please carefully check the connection among Solar panels,
Controller and Battery.
