• A controller can work continuously at full load within an environment temperature range from -25°C to 55°C 3-Stage intelligent PWM charging: Bulk, Boost/Equalize, Float
• Support 3 charging options: Sealed, Gel, and Flooded
• LCD display design dynamically displays the device’s operating data and working condition
• Double USB output
• With simple button settings, the operation will be more comfortable and convenient
• Multiple load control modes
• Energy statistics function
• Battery temperature compensation function
• Extensive Electronic protection

PRODUCT FEATURES:

*USB output ports provide the power supply of 5VDC/2.4A and have short circuit protection.

CONNECTION DIAGRAM:

1. Connect components to the charge controller in the sequence as shown above and pay attention to the “+” and “-”. Please don’t insert the fuse or turn on the breaker during the installation. When disconnecting the system, the order will be reserved.
2. After powering on the controller, check the LCD. Always connect the battery first, in order to allow the controller to recognize the system voltage.
3. The battery fuse should be installed as close to battery as possible. The suggested distance is within 150mm.
4. This regulator is a positive ground controller. Any positive connection of solar, load, or battery can be earth grounded as required.
   CAUTION
   NOTE: Please connect the inverter or other load that has a large start current to the battery rather than to the controller if the inverter or other load is necessary.

• Browse Interface
  

1. When no operation, the interface will be an automatic cycle, but the following two interfaces not be displayed.
   
2. Accumulative power zero clearing: Under the PV power interface, press SET button and hold on 5s then the value blink, press SET button again to clear the value.
3. Setting temperature unit: Under the battery temperature interface, press the SET button and hold on 5s to switch.

• Fault Indication
  

  Status	Icon	Description
  Battery over-discharged		Battery level shows empty, battery frame blink, fault icon blink
  Battery over voltage		Battery level shows full, battery frame blink, and fault icon blink.
  Battery overheating		Battery level shows current value, battery frame blink, and fault icon blink.
  Load failure		Load overloads, Load short circuit

  1When load current reaches 1.02-1.05 times, 1.05-1.25 times, 1.25-1.35 times, and 1.35-1.5 times more than the nominal value, the controller will automatically turn off loads in the 50s,  0s, 10s, and 2s respectively

• Load Mode Setting
  Operating Steps:
  Under the load mode setting interface, press the SET button and hold on 5s till the number begin flashing, then press the MENU button to set the parameter, and press the SET button to confirm.

  1**	Timer 1	2**	Timer 2
  100	Light ON/OFF	2 n	Disabled
  101	Load will be on for 1 hour since sunset	201	Load will be on for 1 hour before sunrise
  102	Load will be on for 2 hours since sunset	202	Load will be on for 2 hours before sunrise
  103-113	Load will be on for 3-13 hours since sunset	203-213	Load will be on for 3-13 hours before sunrise
  114	Load will be on for 14 hours since sunset	214	Load will be on for 14 hours before sunrise
  115	Load will be on for 15 hours since sunset	215	Load will be on for 15 hours before sunrise
  116	Test mode	2 n	Disabled
  117	Manual mode (Default load ON)	2 n	Disabled

  NOTE: Please set Light ON/OFF, Test mode, and Manual mode via Timer1. Timer2 will be disabled and display “2 n”.

• Battery Type
  Operating Steps:
  Under the Battery Voltage interface, press the SET button and hold on 5s then enter into the interface of the Battery type setting. After choosing the battery type by pressing the MENU button, waiting for 5s, or pressing the SET button again to modify it successfully.
  NOTE: Please refer to the battery voltage parameters table for the different battery type.

PROTECTION:

TROUBLESHOOTING:

Faults	Possible Reasons	Troubleshooting
The LCD is off during the daytime when sunshine falls on PV modules properly	PV array disconnection	Confirm that PV wire connections are correct and tight.
The wire connection is correct, LCD does not display	1) the Battery voltage is lower than 9V 2)PV voltage is less than battery voltage	1)Please check the voltage of the battery. At least 9V voltage to activate the controller. 2)Check the PV input voltage which should be higher than the batteries.
Interface blink	overvoltage ge	Check if the battery voltage is higher than the OVD point (over-voltage disconnect voltage), and disconnect the PV.
Interface blink	Battery over-discharged	When the battery voltage is restored to or above LVR point (low voltage reconnect voltage), the load will recover
Interface blink	Battery overheating	The controller will automatically turn the system off. But while the temperature decline to be below 50°C, the controller will resume.
Interface blink	Overload or Short circuit	Please reduce the number of electric equipment or check carefully the loads connection.

SPECIFICATIONS:

^Above the parameters are in the 12V system at 25°C, twice in the 24V system.
