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 for 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.
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.
for 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 for Protection for Battery
Reverse Polarity for 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 for 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.
Before connecting to the solar panel, please connect the controller to the battery; do not use solar panel supply power to the loads directly.
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.
Color-changing LED working voltage indicates area:
Color-changing LED: 12V , 24V
Red LED: 10.5V-11V , 21V-22V
Orange LED: 10.5~11V-13.7V , 21~22V-27.4V
Green LED: ≥13.7V , ≥ 27.4V
Rated Vo1tae: 12V / 24V
Max Load current: 10A , 15A , 20A , 30A ,40A , 5OA , 60A
Input voltage range: 12V~20V/24
Length≤1m:Charge loop drop: <250mV , <250mV , <250mV , <250mV , <250mV , <250mV , <250mV ,
Length≤1m:Discharge loop drop: <50mV , <50mV , <50mV , <50mV , <50mV , <50mV , <50mV ,
Full charge cut: 1.37V~14.4V/27.4V ~ 28.8V/54.8V ~ 57.6V (data under no load condition)
Low voltage cut: 10.5V ~ llV / 21V ~ 24V
Temperature compensation: -3mV/°/cell
No load loss: ≤10mV ≤10mV ≤20mV ≤20mV ≤30mV ≤40mV ≤45mV

Max wire area : 2.5mm2 , 2.5mm2 , 4mm2 , 6mm2 , 8mm2 , 10mm2 , 12mm2
Ambient temperature: -25°—55°
6. TROUBLE SOLUTION
Phenomenon:Green LED off, battery indicator LED is red.
Reason: Low voltage of battery
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.
