LandStar EU series
Solar Charge Controller with USB output
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.
Do disconnect the solar module and fuse/ breakers near to battery before
installing or moving the controller.
Power connections must remain tight to avoid excessive heating from a
loose connection.
Only charge batteries that comply with the parameters of controller.
Battery connection may be wired to one battery or a bank of batteries.
Risk of electric shock, the PV and load can produce high voltages when the
controller is working.
2. Overview
The LandStar EU series controller is a PWM charge controller with USB output
that adopts the most advanced digital technique. It’s an easy operation and
cost efficient controller featured as:
3-Stage intelligent PWM charging：Bulk, Boost/Equalize, Float
Support 3 charging options: Sealed, Gel, and Flooded
Battery status LED indicator can indicates battery situation
Battery temperature compensation function
With humanized settings, operation will be more comfortable and convenient
The USB will provide power supply that can charge for electronic equipment
Battery type and load output can be set via button
Extensive Electronic protection

4. Wiring
(1) Connect components to the charge controller in the sequence as shown
below and pay much 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 power on the controller, check the Battery LED indicator on the
controller, it will be on solid green. Otherwise please refer to chapter 8.
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.

6. Setting Operation
1)Load ON/OFF Setting
When the controller is powered on, press the button to control the load
output.
NOTE: The USB will output when the load is on.
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.

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
prone areas, additional external suppression is recommended.
