※Thank you for selecting the LandStar E/EU series solar charge
controller. Please read this manual carefully before using the
product and pay attention to the safety information.
LandStar E/EU series
——Solar Charge Controller
1.Safety Information
Read all of the instructions in the manual before installation.
DO NOT disassemble or attempt to repair the controller.
Install external fuse or breaker as required.

6. Setting Operation
1)Load ON/OFF Setting
4. Wiring
Step 2：Connect the system in the order of ❶battery ❷ load ❸PV array
in accordance with Figure 2-2,”Schematic Wiring Diagram” and disconnect the
system in the reverse order❸❷❶.
NOTE: While wiring the controller do not close the circuit breaker or
fuse and make sure that the leads of "+" and "-" poles are connected
correctly.
NOTE: A fuse which current is 1.25 to 2 times the rated current of
the controller must be installed on the battery side with a distance
from the battery not greater than 150 mm.
NOTE: If an inverter is to be connected to the system, connect the
inverter directly to the battery, not to the load side of the controller.

When the controller is powered on, press the button to control the load output.
2)Battery Type Setting
Operation:
Step 1: Enter setting mode by pressing button for 5s until the battery status
LEDs are flashing.
Step 2: Select the desired mode by pressing button.
Step 3: The mode will be saved automatically without any operation for 5S and
LED will stop flashing.

Battery Voltage Control Parameters
8. Troubleshooting
Below parameters are in 12V system at 25 ºC, please double the values in
24V system
7. Protection
Battery Over Voltage Protection
When the battery voltage reaches to the set point of Over Voltage
Disconnect Voltage(OVD), the controller will stop charging the battery to
protect the battery from being over charged to break down.
Battery Over Discharge Protection
When the battery voltage reaches to the set point of Low Voltage
Disconnect Voltage(LVD), the controller will stop discharging the battery to
protect the battery from being over discharged.
Load Overload Protection
Load will be switched off when 1.25 times rated current overload happens.
User has to reduce load appliance, then press the button or repower the
controller.
Load Short Circuit Protection
Load will be switched off when load short circuit (≥3 times rated current)
happens. User has to clear short circuit, then press the button or repower
the controller.
High Voltage Transients Protection
The controller is protected against small high voltage transients. In lightning
①When load current reaches1.25 times 1.5 times and 2 times more than
nominal value, the controller will automatically turn off loads in 60s, 5s and 1s
respectively.
10. Disclaimer
This warranty does not apply under the following conditions:
Damage from improper use or use in an unsuitable environment.
PV or load current, voltage or power exceeding the rated value of controller.
User disassembly or attempted repair the controller without permission.
The controller is damaged due to natural elements such as lighting.
The controller is damaged during transportation and shipment.
Any changes without prior notice! Version number：V2.0
prone areas, additional external suppression is recommended.
