Solar Charge Controller

Safety Information

• Read all the instructions in the manual before installation.
• DO NOT disassemble or attempt to repair the controller.
• Install an external fast-acting fuse or breaker as required.
• Disconnect the solar module and fast-acting fuses/breakers near the batterybefore 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 controller’s parameters.
• The battery connection may be a single battery or a bank of batteries.
• Risk of electric shock! The PV and load can produce high voltages when thecontroller is working.

Overview

The LandStar E/EU series controller is a PWM charge controller 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, and Float

• Support 3 charging options: Sealed, Gel, and Flooded

• Battery status LED indicator indicates battery situation

• Battery temperature compensation function

• With humanized settings, the operation is more comfortable and convenient

• The USB provides a power supply that can charge electronic equipment(LS
  EU series only)

• Battery type and load output can be set via the button

• Extensive Electronic protection

Product Features

Wiring

Connect the system in the order of ❶battery load PV array following Figure 2-2,” Schematic Wiring Diagram,” and disconnect the system in the reverse order❸❷❶.
NOTE: Do not connect the circuit breaker or fast-acting fuse while wiring the controller. Ensure that the leads of “+” and “-” poles are connected correctly.
NOTE: A fast-acting fuse whose current is 1.25 to 2 times the controller’s rated current must be installed on the battery side with a distance from the battery not greater than 150 mm.
WARNING: The controller has no PV reverse connection protection; please connect it correctly.

LED Indicators

NOTE:
① The above voltage values are measured in the 12V system at 25℃; please double the values in the 24V system.
② “○” states LED indicator on; “×” states LED indicator off.

Operating

1. Load ON/OFF Setting Press the button to control the load output when the controller is powered on.
2. Battery Type Setting

Operation:
Step 1: Enter the setting mode by pressing the button for 5s until the battery status LEDs are flashing.
Step 2: Select the desired mode by pressing the button.
Step 3: The mode is saved automatically without any operation for 5S, and the LED stops flashing. Battery Type Indicator shows as below:

NOTE: “○” states LED indicator on “×” states LED indicator off

Protection

• Battery Over Voltage Protection
  When the battery voltage reaches the Over Voltage Disconnect Voltage(OVD), the controller stops charging the battery to protect the battery from being overcharged.

• Battery Over Discharge Protection
  When the battery voltage reaches the Low Voltage Disconnect Voltage(LVD), the controller stops discharging the battery to protect the battery from being over-discharged.

• Overload Protection
  The load is switched off after a delay when the load current exceeds 1.25 times the rated current. The user must reduce the load appliance, press the button, or restart the controller.

• Load Short Circuit Protection
  The load is switched off when the load short circuit (≥3 times the rated current) happens. The user must clear the short circuit faults, press the button, or restart the controller.

• High Voltage Transients Protection
  The controller is protected against small high voltage transients. In lightning-prone areas, an external lightning arrester is recommended.

Troubleshooting

The charging LED turns off during the daytime when sunshine falls on PV modules properly.| PV array disconnection| Confirm that PV and battery wire connections are correct and tight.
No LED indicator| Battery voltage may be less than 8V| Measure battery voltage with the multi-meter. Min.8V can start up the controller.
Charging LED fast flashes.| Battery over voltage| Check if the battery voltage is higher than the OVD, and disconnect the PV.
LED1 fast flashes.| Battery over-discharged| The load will recover when the battery voltage is restored to or above the LVR (low voltage reconnect voltage).
Load LED flashesslowly.| Overload*| 0 Please reduce the number of electric equipment.
C) Press the button or restart the controller.
Load LED fastflashes.| Load short circuit| (i) Check carefully loads connection, clear the fault.
® Press the button or restart the controller.

• When the load current exceeds 1.25 times, 1.5 times, and 2 times the rated value, the controller can automatically turn off loads after 60s, 5s, and 1s, respectively.

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 exceeds the controller’s rated value.
• User disassembly or attempted to repair the controller without permission.
• The controller is damaged due to natural elements such as lighting.
• The controller is damaged during transportation and shipment.
