Product Features

Wiring

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

2. The following rules must be observed when modifying the parameters value in user  battery type (factory default value is the same as sealed type):
   A. Over Voltage Disconnect Voltage > Charging Limit Voltage” Equalize Charging
   Voltage ” Boost Charging Voltage ” Float Charging Voltage > Boost Reconnect Charging Voltage.
   B. Over Voltage Disconnect Voltage > Over Voltage Reconnect Voltage.
   C. Low Voltage Reconnect Voltage > Low Voltage Disconnect Voltage ” Discharging Limit Voltage.
   D. Under Voltage Warning Reconnect Voltage > Under Voltage Warning Voltage

   The load is turned ON/OFF via the button.

2. Light ON/OFF

Time Control
Control the load on/off time through setting real-time clock

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).

• 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.
