Safety Instructions
1.Read all of the instructions and cautions in the manual before
installation.
2.There are no repairable parts for this controller,do not disassemble or
attempt to repair the controller.
3.Keep the controller from the water.
4.Make sure all connections with controller are tight.
5.Please read the product installation steps to ensure all connections
are correct.
Please follow the safety instructions for operation, the damage caused
by not following the safety instructions shall be borne by the individual.
General Safety Information
1.NEVER connect the solar panel array to the controller without a
battery. The battery must be connected first.
2.Ensure input voltage does not exceed 55 Voc to prevent permanent
damage.
3.Ensure that the output current of the solar panel does not exceed the
rated charging current of the controller.
Charge Controller Safety
1 . Do NOT let the positive (+) and negative (-) terminals of the battery
touch each other.
2. Explosive battery gases may be present while charging.
Be certain there is enough ventilation to release the gases.
3. Be careful when working with large lead-acid
batteries. Wear goggles and have fresh water available in case there is
contact with the battery acid.
4. Over-charging and excessive gas precipitation may damage the
battery plates and activate material shedding on them. Too high of an
equalizing charge or too long of one may cause damage. Please
carefully review the specific requirements of the battery used in the
system.

1. The positive and negative poles of the battery must be connected to
the battery terminals of the controller first.
2. Finally, connect the positive and negative poles of the solar panel to
the PV terminals of the controller.
Note: Please strictly follow the above sequence for connection,
otherwise the controller may be damaged. The disassembly sequence
is opposite to the wiring one.
Caution
1. First make sure your battery system is 12V or 24V.
2. Ensure that the maximum open-circuit voltage of the solar system
does not exceed 55V.
3. Ensure that the maximum output current of the solar panel does not
exceed rated current.（10A/20A/30A）
4. Ensure that the voltage of the solar panel is higher than the battery
voltage.

Error code Cause of failure
Normal.
Battery voltage is too low.
Battery voltage has exceeded

limit(80°C/176°F).
Disconnect and reconnect
with correct wire polarity.
Solution
/
Check if the system voltage is
set correctly or turn off the
load and continue charging
until the battery voltage
reaches the recovery voltage.
Check if the system voltage is
set correctly.
Place the controller in a
suitable temperature
environment.
Reduce the power of the solar
panel system.
Reduce the voltage of the
solar panel system and the
voltage is lower than 55V to
recover.
Disconnect and reconnect
with correct wire polarity.

Bulk Charge: Constant current charging, providing the maximum current
to the battery until the battery voltage reaches the constant voltage stage
(boost charging voltage or equalize charging voltage).
Boost Charge: Constant voltage charging, the battery is charged for 120
minutes at an elevated charging voltage.
Float Charge: After the boost charge, the controller will reduce the battery
voltage by reducing the charging current, and let the battery voltage be
maintained at the set value of the float charging voltage. During the float
charging stage, the battery is charged very slightly to ensure that the battery
is maintained in a fully charged state. In the float charging stage, the load can
obtain nearly all solar power. If the load exceeds the power that solar energy
can provide, the controller will not be able to maintain the battery voltage at
the float charging stage. When the battery voltage is low to the set value of
boost charge return voltage, the system will exit the float charging stage and
enter the bulk charging stage again.
