3 Wiring

Installation Procedure:

Connect the system in the order of ❶battery ❷ load  ❸PV array in accordance with Fi gure 2”Connection diagram” and disconnect the system in the reverse order❸❷❶.

NOTE: The LS-B series is a positive ground controller. Any positive connection of solar, load or battery can be earth grounded as required.

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.

6 Protections

 PV Over Current

When the charging power of the PV array exceeds its rated power, it will be charged at the rated power.

 PV Short Circuit

When not in PV charging state, the controller will not be damaged in case of a short-circuiting in the PV array.

 PV Reverse Polarity

When the polarity of the PV array is reversed, the controller may not be damaged and can continue to operate normally after the polarity is corrected.

 Battery Reverse Polarity

Fully protected against battery reverse polarity; no damage to the controller will result.

Correct the miswire to resume normal operation.

 Battery Over Voltage

When the battery voltage reaches the over voltage disconnect voltage, it will automatically stop battery charging to prevent battery damage caused by over-charging.

 Battery Over Discharge

When the battery voltage reaches the low voltage disconnect voltage, it will automatically stop battery discharging to prevent battery damage caused by over-discharging. (Any controller connected loads will be disconnected. Loads directly connected to the battery will not be affected and may continue to discharge the battery.)

 Battery Overheating

The controller can detect the battery temperature through an external temperature sensor. The controller stops working when its temperature exceeds 65 °C and begins working when its temperature is below 55 °C.

 Load Overload

When the load is overloading (The overload current is ≥ 1.05 times the rated load

current), the controller will automatically cut off the output. If the load reconnects automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button restarting the controller, switching from Night to Day (nighttime > 3 hours).

 Load Short Circuit

When the load is short circuited (The short circuit current is ≥ 2 times the rated controller

load current), the controller will automatically cut off the output. If the load reconnects the output automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button, restarting the controller or switching from Night to the Day (nighttime > 3 hours).

 Controller Overheating

The controller is able to detect the temperature inside the battery through an optional remote sensor. The controller stops working when its temperature exceeds 85 °C and begins to working when its temperature is below 75 °C.

 TVS High Voltage Transients

The internal circuitry of the controller is designed with Transient Voltage Suppressors (TVS) which can only protect against high-voltage surge pulses with less energy. If the controller is to be used in an area with frequent lightning strikes, it is recommended to install an external surge arrester.

7 Troubleshooting

Faults

Possible reasons

Troubleshooting

Charging LED indicator off during daytime when sunshine falls on PV modules properly

PV array disconnection

Confirm that PV and battery wire connections are correct and tight

Wire connection is correct, the controller is not working.

Battery voltage is lower than 8V

Please check the voltage of battery. At least 8V voltage to activate the controller.

Battery indicator green slowly flashing

Battery over voltage

Check if battery voltage is higher than OVD(over voltage disconnect voltage), and disconnect the PV.

Battery indicator red on solid

Battery over discharged

When the battery voltage is restored to or above LVR(low voltage reconnect voltage), the load will recover

Battery indicator red slowly flashing

Battery Overheating

The controller will automatically turn the system off. But while the temperature decline to be below 55 ºC, the controller will resume.

Charge, Load and Battery(orange)indi cator flashing

Controller Overheating

When heat sink of controller exceeds 85℃, the controller will automatically cut input and output circuit. When the temperature below 75℃,the controller will resume to work.

Load indicator red slowly flashing

Load Overload

①Please reduce the number of electric equipments.

②Restart the controller. ③wait for one night-day cycle (night

time>3 hours).

Load indicator red fast flashing

Load Short Circuit

①Check carefully loads connection, clear the fault.

②Restart the controller. ③wait for one night-day cycle (night

time>3 hours).
