Introduction and functions

2.1. Introduction
Thanks for purchasing our MPPT solar charge controller with LED.
This MPPT series controller is designed to charge the battery in an off- arid solar system. And itis for personal use only. With the technology of maximum power point tracking(MPPT), it has a high efficiency to charge your solar system and provide you better solar energy.
Main characteristics are listed as below:

• MPPT Technology offers high efficiency of solar system.
• Automatic voltage regulation for 12 or 24V system.
• LED indicators.
• 3-stage U curve charge principle.
• Negative grounding
• Dual teminals for solar panel input.
• Battery type: AGM, GEL Lead-acid Battery or Lithium iron phosphate Battery
• Temperature-compensation, it measures the ambient temperature to determine the charging voltage.

2.2. Function and protection

• Step-up function
  The MPPT solar controller is equipped with a step-up function. The controller charges the battery even if the solar voltage is lower than the battery voltage.
  Note: please note that this function is not given when the solar voltage is lower than the solar controller’s own consumption. In this case, the solar controller switches to standby mode. (See explanation of standby mode)

• Standby mode
  When the solar charging power is lower than the solar controllers own consumption, the standby mode automatically activate after 30 seconds.

• Over-discharge protection
  With battery voltage decreasing to 11V/22V. the controller switches the load off automatically. As soon as the battery is recharged, the load is switched on automatically.

• Over-charge protection
  The controller stops the charging process when the battery is fully charged. This prevents the battery from being damaged by overcharging.

• Over-temperature protection
  The controller switches off the output current when the temperature inside the device is too high. When the solar controller cools down to normal operating temperature, charging current will recover automatically.

• Desulfation function (pulse charging)
  Following the regular charging steps, the solar controller starts pulse charging to the battery. This causes sulfate layers in the battery being dissolved which prolongs the battery lifetime significantly

• Reverse polarity protection
  The controller is protected against incorrect connection to the battery Ensure correct polarity when connecting. If wrong connection occurs, the fuse blow. Replace the fuse to reset the device.

Mounting and connection

• The controller is designed for indoor use only.
• Protect it from direct sunlight and place it in a dry environment.
• Never install it in humid rooms (like bathroom).
• The controller and the battery must be installed in the same room.
• The controller warms up during operation. Must be installed on a non-flammable surface only. Installation: connect the controller by following the steps below to avoid installation problems.

Please see the picture, it shows how to install the controller on the wall by screws.

• Make sure that the ventilation slits are unobstructed
• Mount the controller in a way that ensures there is enough space below and above for ventilation

4.1. Connecting to the battery
Connect the wire to the battery with the cortect polarity. To avoid overheating the wires or causing the voltage drop from the wires, please select the wire size based on controller’s rated current.
Recommended wire size: 20A: min 4mm2, 30A min Bmm2 40A: min 8mm2, 50A: min 10mm2, 60A: min 12mm2 Note: Better wire size and less length give smaller power loss and less voltage drop.
We strongly recommend you to connect a fuse directly to the battery to protect any short circuit in the battery wiring. The fuse must at least withstand the controller’s rated current . For example, you can use a 40A slow-blow fuse with a 30AMPPT controller.
Note: wrong connection, the beeper alarms.
4.2, Connecting to the solar panel
Comnect the wires tothe solar panel with proper polarity. To avoid overheating the wires or causing the voltage drop from the wires, please select the wire size based on controller’s rated current.
Recommended wire size: 20A: min 4mm2, 30A min 6mm2, 40A: min 8mm2, 50A: min 10mn2, B0A: min 12mm2. Note: Place the posiive and the negative wires closely to each other to minimize electromagnetic effects.
Note: Solar panels provide supply as soon as exposed to sunlight. Mind the solar panel manufacturer’s recommendations.
Note: If wrong connection, the beeper alarms.
4.3. Connecting to the load
Connect the wires leading to the loads with proper polarity.
Ifthe DC loads were protected by short circuit, over current or low voltage, the faultled lit turns red and flash.
There is a fuse inside of the controller for protection. If fault happens, the fuse blow. 4.4. Grounding the Solar System
It any grounding s required, always do this on the negative terminals(any negative terminal). 4.5. Replacing the internal fuse
The controller is equipped with an internal safety fuse. To replace the fuse, the housing of the solar controller needs to be opened. You need to disconnect the cables and the four screws on the housing. Then replace the fuse by the spare fuse given when purchasing.
Note: replace the fuse only by a fuse in the same type and rated current!

Operation and recommendations

Protect the solar charge controller against electromagnetic effects, impacts and vibrations.

• Protect the solar charge controller against heat. If the controller become 100 hot due to high ambient temperature, the overheat protection starts and switches the device off to avoid consequential damage. Do not operate the device until it cools down.
• Avoid sudden change of the temperature. The sudden change of the temperature may cause the formation of condensation water inside the solar charge controller. In this case, the solar charge controller needs a new ambient temperature and to be placed at a wel ventilated space for at least one hour.

5.1. System Voltage
The MPPT controller adjusts its voltage automatically to fit the 12V or 24V system by detecting battery voltage. The default option is 12V. Once the battery voltage exceeds 18.0V, the controller judges that it is a 24V system. 5.2
Recommendations for Use

• The controller warms up during normal operation. If there is an insufficient ventiation (e.g. in an installation cabinet), the controller limits the solar charge current to prevent overheating.
• The controller does not need any special maintenance or service. Remove dust with a dry tissue.
• The battery need to be fully charged at least once a month, otherwise the battery wil be permanently damaged.

5.2. Battery notes

• If used improperly, batteries are a high risk for humans, animals and the environment. Always follow the safety instructions of the battery manufacturer!
• Lead-acid batteries contain aggressive corrosive acids. Avoid eye and skin contact with liquids from the battery! Never disassemble. Iead batteries! If the acid is brought into contact with eyes or skin, immediately flood with running, clear water! Then seek for medical help immediately! If acid gets on your clothes, remove the contamina- ted clothes immediately and flood the affected parts of the skin with running, cool water thoroughly.
• Battery stores a large amount of energy. Under any circumstances, never short-circuit the batteries. We recommend you to connect a fuse (slow-blow type) directly to the battery terminal.
• Please read the safety instructions of the battery manufacturer. If in doubt, consult your dealer or installer.
