Safety Tips

• Review this manual thoroughly before attempting installation.
• Beware of any nearby electrical equipment that may interfere with installing this device.
• Solar panels can generate high voltages and currents, make sure your solar panels are completely covered from sunlight during installation. It is recommended that installation be performed by a qualified electrician.
• Connecting wires to this device can generate sparks, please wear proper insulation gear while installing this device.
• To avoid damage to the battery or controller, use proper fuses in wiring. Please do not hesitate to contact the professions if you need help with fuse sizing.
• Always keep children away from this device.
• Be certain to use the correct gauge of wire, see below for a table of recommended wire size for various current loads.
• Lithium batteries are not allowed to be reverse connected, for risks might happen in battery activation if the wiring connection reversed.

Product Features

Thank you for choosing our products. This MPPT solar charge controller is a device for solar charge regulation and direct current output load control This device is mainly used in small and medium sized off-grid solar power systems.
These MPPT charge controllers have features as follows:

• By continuously checking solar panel power output changes, the controllers employ multiple MPPT charge algorithms in combination to boost charging efficiency in different weather and temperature conditions.

• Built-in buffer, allows max 25% exceeding rated power input

• Charging modes available for most common deep-cycle battery types in the market, including AGM (sealed lead acid batteries), GEL, Flooded, and Lithium.

• Allows mobile phone APP operation for monitoring and parameters settings, with connection of external blue tooth communication module (optional accessory, not in the standard package list).

• Auto recognition ofl2V/24V battery system voltage by M2420N/M2430N/M2440N models; auto recognition ofl2V/24V/36V/48V battery system voltage by M4860N model Lithium battery excluded from this feature.

• Supports recording of system running data including power generated and power utilized for up to 300 days, compatible with monitoring App through IOS and Android.

• We have built-in BT communication module in this controller and we provide APP PV Charge Pro for mobile phone monitoring and operation. You can search “PV Charge Pro”and download the APP at IOS APP Store and Google Play Store.
  (The password in setting page for APP “PV Charge Pro”: 723456)

• Provides multiple load control mode options for light based, time based and manually adjusted scenarios. Low no-load loss.

•  Industrial grade design with reverse polarity protection for solar panels, battery.

Mounting Instruction

• Step 1
  Find a cool dry and weather safelocation for installation.

• Step 2
  Mark the controller’s mounting holes on the mounting surface.

• Step 3
  Drill holes in the marked mountiong hole location.

• Step 4
  Insert pilot scre\NS in the mounting hole.

• Step 5
  Fasten the controller into the pilot screvvs.

• Step 6
  Continue to wire battery, solar, DC load andother accessories to the controller.

Wire Connection Sequences

During installation of your MPPT controller, please follow the order of connection below:

• Connect the positive battery wire followed by the negative battery wire.
• Make sure your solar panels are fully covered to prevent electrical shock
• Connect the positive solar array output wire followed by the negative solar array output wire.
• Connect DC load wires to the DC load output (if applicable).
• Connect the external temperature sensor to its terminal shown above.
• Download APP PVChargePro and turn on the BT function in the mobile phone. Testing the APP function with the controller.

Controller Specification

• The variable “n” is adopted as a multiplying factor when calculating parameter voltages, the rule for “n” is Listed aS: if battery system voltage is 12V, n=l; 24V, n=2; 36V, n=3; 48V, n=4.
• For example, the equaLize charge voltage for a 12V FLD (Flooded) battery bank is 14.8V”l=l4.8V. The equalizing charge voltage for a 24V FLD (Flooded) battery bank is 14.8V’2=29.6V.
