Maximum Power Point Tracking Technology
This is a MPPT charge and discharge controller, With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of photovoltaic array, in order to obtain the maximum solar energy in time, which remarkably improves energy efficiency the maximum conversion efficiency can reach 99.5%; the maximum power point tracking is automatically traced, the charging efficiency is increased by 10% to 30% (compared with the controller without maximum power point tracking), with high efficiency / energy efficiency / intelligence. Copper Coil

Battery Charging Stage

The controller have 3 stages charge mode, Constant Current Charging, Constant Voltage Charging and Floating Charging for rapid, efficient, and safe battery charging.

1. Constant Current Charging (Bulk Charging)
   In this stage, the battery voltage has not yet reached constant voltage (Equalize or Boost Voltage), the controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging).

2.   Constant Voltage Charging( Equalize and Boost Charging)
   When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant voltage charging mode, this process the charging current will drop gradually. The Constant Charging has 2 stages, equalize and boost. These two stages are not carried out constantly in a full charge process, and its boost charging is start at 25th of each month.

3. Floating Charging
   After the constant voltage stage, the controller will reduce charging current to maintaining the battery voltage on the Floating Voltage set point. Charging the battery with a smaller current and voltage on Floating Voltage stage, while maintaining full battery storage capacity. In Floating charging stage, loads are able to obtain almost all power from solar panel. If loads exceed the power, the controller will no longer be able to maintain battery voltage in Floating charging stage. If the battery voltage remains below the Recharge Voltage, the system will leave Floating charging stage and return to Bulk charging stage.

 Installation Instructions

Wiring sequence: 6-5-4-3-2-1
When installing the wire, first loosen the screw counterclockwise

• Prepare complete installation tools, materials and cables. Please select the appropriate cable.
• Ensure that the current density is < 4A / mm2, which will help to reduce the pipeline pressure drop.
•  Check whether the installation site meets relevant safety requirements and avoid humid, dusty, flammable, explosive and corrosive environment
• Install the controller fixed on the vertical plane to ensure the installation hole diameter and hole spacing. In order to ensure good heat dissipation of the controller, 10cm space is reserved at the bottom of the controller
•  As shown in the right wiring sequence: load, battery and solar energy. (please be sure to connect the circuit breaker or switch and do not operate with electricity)
• The panel is connected to the controller to ensure the polarity of the load, battery, solar panel and controller.
• Warning: in order to prevent accidents (high pressure or high temperature), non professionals shall not engage in loading and unloading operations.
• Be very careful when installing batteries, especially lead-acid batteries filled with water. Please wear goggles and clean any place in contact with battery acid with fresh water.
•  Keep the battery away from any metal object that may cause a short circuit to the battery.
• A gap of at least 150 mm to 300 mm is required between the top and bottom of the controller to ensure normal air circulation. Ventilation and cooling fans are strongly recommended if installed in sealed enclosures.
