CAUTION: 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.
Step 1: connect the battery ①
CAUTION: While wiring the controller do not turn on the breaker or fuse and make sure that the leads of "+" and "-" poles are
connected correctly.
Step 2: Connect the PV ②
CAUTION: If the controller is used in ungoverned or frequent lightning area, must install a reasonable arrester in the PV array
input side.
Step3: Connect the Remote temperature sensor cable ③
NOTE: The controller will charge or discharge the battery at 25℃ as default and no temperature compensation, when the
temperature sensor is damaged.
CAUTION: Make sure that the battery voltage sensor cable of "+" and "-" poles are connected correctly when wiring.
Step4: Connect the Remote battery voltage sensor ④
Refer to the chaper 4 "Remote set battery type".

When the charging current of the PV array exceeds the controller’s rated current, it
will be charge at the rated current.

Protection Instruction
PV Over current
When the voltage of PV will exceed 50V, the controller will stop charging and
restart to charge when the PV voltage is below 45V
PV Over voltage
When the PV voltage is below 50V and short circuit, the controller will stop
charging; the controller restart to charge when the fault is cleared, it don’t
damaged the controller.
PV short circuit
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.
PV Reverse Polarity
Prevents the battery from discharging to the PV module at night.
Night Reverse Charging
Fully protected against battery reverse polarity; no damage will occur to the
battery. Correct the miswire to resume normal operation.
Battery Reverse Polarity
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 Voltage
The controller can detect the battery temperature through an external temperature
sensor. The controller stops working when its temperature exceeds 65 °C and
restart to work when its temperature is below 55 °C.
Battery Overheating
The controller is able to detect the temperature inside the battery. The controller
stops working when its temperature exceeds 85 °C and restart to work when its
temperature is below 75 °C.
Controller Overheating
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.
