DocumentDocumentHUIZHOU EPEVER TECHNOLOGY CO., LTD. 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. Do not install this product in humid, salt spray, corrosion, greasy, flammable, explosive, dust accumulative, or other severe environments. Solar Charge Controller 1. 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 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 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 the controller is working. 2. 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 3.

Wiring Connect the system in the order of battery load PV array following Figure 2-2," Schematic Wiring Diagram," and disconnect the system in the reverse order. 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. 1 Tel: +86-752-3889706 Website: www.epever.com Figure 2 Connection diagram 5.

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 Tel: +86-752-3889706 Website: www.epever.com lightning-prone areas, an external lightning arrester is recommended. 8. Troubleshooting Faults Possible reasons Troubleshooting The charging LED turns off during the daytime when sunshine falls on PV PV array disconnection Confirm that PV and battery wire connections are correct and tight. modules properly. Battery voltage Measure battery voltage with No LED indicator may be less than the multi-meter. Min.8V can 8V 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. The load will recover when the LED1 fast flashes. Battery over-discharged battery voltage is restored to or above the LVR (low voltage reconnect voltage). Please reduce the number Load LED flashes slowly. Overload of electric equipment. Press the button or restart the controller. Check carefully loads Load LED fast flashes. Load short circuit 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. 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 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. 9.
