7. Lithium battery configuration
7.1 Attention of using the lithium battery
Technician required for maintenance and repairing, do NOT disassemble and
repair the equipment personally.
The operation of overload may cause the battery to be damaged or safety
accidents.
Turn off the equipment after useto save battery life and avoid any problem or
accident caused by heating during standby mode.
Fully charge the battery monthly to ensure the life of the battery, if the equipmentis
not used in the long term,
The equipment should be stored in a cool, dry, and ventilated room, also away
from direct sunlight, inflammable, and explosives.
Keep the equipment away from water, which may cause device failure, short circuit,
or safety accidents.
Do NOT throw lithium batteries into water or fire, which may cause the battery
damaged or safety accidents.
Keep the lithium battery away from children.
Do NOT disassemble the lithium battery or try to penetrate it with sharp metal
objects, which may cause fire or explosion.
Do NOT throw the wasted battery away randomly,and send it to the battery
recycling department.

10. Protection
10.1 LD150S-N1/N1R/N2/N2R/N4/N4R/N4Sprotection
PV Reverse
Polarity
When the polarity of the PV array is reversed, the device may not
be damaged and can continue to operate normally after the
polarity is corrected.
LithiumBattery
Reverse Polarity
Fully protected against battery reverse polarity; no damage will
occur to the battery. Correct the miswire to resume normal
operation.
Lithium Battery
Over Voltage
When the battery voltage reaches the overvoltage disconnect
voltage(OVD), it will automatically stop battery charging to prevent
battery damagecaused by over-charging.
LithiumBattery
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.
Load Overload
When the overload current is ≥ 1.5 times the rated load current,
the device will automatically cut off the output.
Load Short Circuit
When the load is short circuit the device will automatically cut off
the output.
High Voltage
Transients
The internal circuitry of the device 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.
