1. SAFETY
Full consideration to
the safety of persons and property has been given when designing the products.
However the incorrect connection may cause the system breakdown or even safety
accident. For your safety and benefits, the following rules must be complied
during the operation.
. Installation of this product shall be tinder the guidance of the
professionals in this field.
. Prevent this controller from water, humidity and insects, to avoid
short-circuit.
. Keep children and incapable persons away from the controller
. Keep the controller away from electrical heater, heating machine and other
high temperature electrical appliances; avoid the controller suffering from
insulation directly.
. Please check the rated voltage of solar panel, battery, and loads before
connection. 12V rated voltage is 12V, 24V rated voltage is 24V, 48V rated
voltage is 48V.
. Make sure connections between positive and negative poles of Solar panels,
Battery and Loads are correct.
. The diameter of connecting cable must be matched with the requirements of the
current. Do not use thinner diameter cable, the thinner diameter. The larger
resistance, this will cause higher temperature and output power
decreasing.
. The total rated current of solar panel and loads must be smaller than the
rated current of the controller.
. Components of system must be correctly and firmly connected. Prevent the
terminals from oxidation and moldy, to avoid connection trouble.
2. FEATURES
. MPPT solar charge
controller MPPT10-60: Compared with normal solar charge controller, this MPPT
controller could increase efficiency by 10%-30%.
. This controller can charge and discharge at the same time.
. This MPPT controller has perfect SOC function, control charge current, and
supply power to the loads.
Function:
. Always keep the
battery on fill voltage condition.
. Prevent the battery from over-charging.
. Prevent the battery from over-discharging.
. Prevent the battery from reverse charging to solar panels during
nights.
. Reverse Polarity Protection for Battery
. Reverse Polarity Protection for Solar Panels
. When the battery voltage is low, the controller will automatically cut off
the load from the system. If the voltage of battery is back to normal and the
load will restart working.
. Thunder protection
. According to the battery voltage grade, the controller can automatically set
charge-off voltage, the load-off voltage, the load- restore voltage. (The
parameter is default under 25℃ condition, locked by the CPU procedure, cannot
adjust.)
. The controller will
automatically compensate the temperature of the charging voltage according to
the changes of ambient temperature.
Warning:
Before connecting to
the solar panel, please connect the controller to the battery; do not use solar
panel supply power to the loads directly.
Notes:
Do not use lamplight
to charge the solar panel (lamplight is too weak to charge)
DC power source to replace the solar panel will cause troubles to controller.
Choose the suitable
wire which diameter should not be too small, please refer to the parameter.
4. INDICATE LIGHT AND BUTTON
. When Red LED
(CHARGE) is on, battery is charged up strongly; When Red LED is flickering,
battery is MPPT charged up in constant voltage; when Red LED is oft charge off
. When Green LED (LOAD) is on, loads are working; when Green LED (LOAD) is off,
loads stop working.
. Three Color-changing LED (BATTERY), When light is red, it indicates low
voltage, green indicate battery full charged, orange indicate normal status.

6. TROUBLE SOLUTION
Phenomenon:Green
LED off, battery indicator LED is red.
Reason: Low voltage of
battery
Solution:
A:Cut off the power,
disconnect the load; reconnect the load after the charge become normal.
B:Battery charge
problem: Increase the solar panel power or change the battery.
Phenomenon:Battery indicator
LED is orange and Load indicator LED is green, the loads cannot work.
Reason: Over load or short-circuit causes the
controller inner fuse cut off
Solution: 10-20
minutes after eliminated the malfunction, the fuse will automatically back to
working.
