When using the product, please do remember the below information to avoid fire,
lightning or other personal injury:
Warning!
Ensure input DC voltage is no more than Max. DC voltage (Voc) .Over voltage
may cause permanent damage to solar charge controller or other losses, which
will not be covered by the warranty! This chapter contains important safety and
operating instructions. Read and keep this operation guide for future reference.
Warning!
Authorized service personnel must disconnect both DC and battery bank power
from the solar charge controller before attempting any maintenance or cleaning
or working on any circuits connected to the solar charge controller.
● Before using the solar charge controller, please read all instructions and cautionary
markings on the solar charge controller, and all corresponding sections of this
guide.
● Contact I-Panda for any questions or concerns about your controller. Trying to
modify or repair it may result in a fire, electric shock, or injury.
● To reduce risk of fire and electric shock, make sure that existing wiring is in good
condition and that all wire is properly sized. Do not operate the solar charge
controller with damaged or substandard wiring.
● Do not disassemble the solar charge controller. It contains no user-serviceable parts.
See Warranty for instructions on obtaining service. Attempting to repair the solar
charge controller by yourself may result in a risk of electric shock or fire and will
void your warranty.
● To reduce the risk of electric shock, authorized service personnel must use
insulating tools when connecting or working on the controller.
● Keep away from flammable, explosive materials to avoid fire.

• Mount on a solid surface.
• The mounting location should be accessible at all times.
• The charge controller should be easy to remove from the mounting location at any
time.
• The ambient temperature should be between -4 and 140F (-20 and 60 °C) to
guarantee optimal operation.
Danger:
Possible fire and explosion hazard
The charge controller enclosure may become hot during operation.
• Do not mount the charge controller on flammable construction material.
• Do not mount the charge controller near highly flammable materials.
• Do not mount the charge controller in potentially explosive areas.
• Do not expose the charge controller to direct sunlight to avoid power
loss due to overheating.

5. MPPT Controller Connection
5.1 Safety
Danger!
High voltages are present and dangerous
• Disconnect the PV array using a disconnection unit and secure it against
accidental reactivation.
• Disconnect the circuit breaker and ensure that it cannot be reconnected.
• Ensure that no voltage is present in the system.
Warning:
Risk of injury due to electric shock。
If all cables with different voltages are routed in parallel, damaged cable
insulations may lead to a short circuit.
• Route all cables separately if possible.
Warning:
Over voltage can destroy the system.
• Use an external over voltage protector in areas with an increased risk of
lightning.

5.2 Connections of the PV power system
5.2.1 PV String
Solar charge controller device can be connected in parallels to charge the same battery
bank. Please select PV modules with excellent function and reliable quality. Solar
panels may be connected in series or in parallel. Open-circuit voltage (Voc) of module
arrays connected in series should be less than Max. DC input Voltage (150V) of the
MPPT solar charge controller; operating voltage (Vmax) should conform to MPPT
voltage range.
Please use PV cable to connect modules to the charge controller. It should be outdoor
uv rated and we recommend 10Awg to prevent excessive losses due to distance. It is
beneficial to increase the dc voltage to optimize performance and decrease
inefficiencies.

5.3.2 Firmware(Solar Eagle)introduction
We have developed software that completely monitors and allows for many
parameter changes via a computer.
6. Steps for Commissioning or Shutdown
6.1 MPPT controller work step
Please make sure the controller is properly wired.
Step 1: Close the battery breaker or make connection with the battery bank. Some
led’s and the lcd should illuminate.
Step 2: Now make the PV connection. If the PV module voltage is in the charging
range, then the controller will start to work .
6.2 Steps for Proper Shutdown
Step 1: Open the PV breaker to disconnect panels from controller.
Step 2:Open the battery breaker or disconnect controller from battery bank. This
will completely shut the controller to off.
Caution: Follow the steps for shutdown to avoid damage
.
Warning：NEVER disconnect the battery while charging.
This will cause permanent damage to the controller and is not
covered under the warranty. Always disconnect PV panels
first.
Caution :Please follow the steps to ensure proper programming.
