SAFETY INSTRUCTIONS
The following symbols are used throughout this manual to indicate potentially dangerous conditions or mark important safety
instructions. Please take care when meeting these symbols
WARNING: Indicates a potentially dangerous condition. Use extreme caution when performing this task
CAUTION: Indicates a critical procedure for safe and proper operation of the controller.
LIABILITY EXCLUSION
The manufacturer shall not be liable for damages, especially on the battery, caused by use other than as intended or as mentioned
in this manual or if the recommendations of the battery manufacturer are neglected. The manufacturer shall not be liable if there has
been service or repair carried out by any unauthorized person, unusual use, wrong installation, or bad system design.
OVERVIEW
This series solar controller is based on an advanced maximum power point tracking (MPPT) technology developed, dedicated to
the solar system, the controller conversion efficiency up to 98%.
It has several outstanding features, such as:
• A combination of multiple tracking algorithms enables tracking the maximum power point quickly and accurately.
• Innovative Max Power Point Tracking (MPPT) technology, tracking efficiency >99.9%.

• LCD display design read operating data and working condition easily.
• Real-time energy statistics function.
• 12/24/48V automatic recognition.
• Flexible System battery selection: Liquid, Gel, AGM and Lithium.
• Extends battery life through accurate remote temperature sensor.
• Controller is protected against over-temperature due to built-in power reduction function.
• Four stages battery charging process: MPPT, boost, equalization, float.
• Dual automatic protection to avoid exceeding the rated charging power and current.
• Multiple load control modes: Always on, Street lamp, User-defined Mode.
• Two USB interfaces (only -EU model).
• IoT wireless communication or Bluetooth communication functions optional.
• With the wireless communication function of the IoT, the controller can be connected remotely through IoT/GPRS.
• Monthly charging data can be calculated and displayed by grouping and graphs.

MPPT
MPPT Profile
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could detect the real-time power of the solar
module and the maximum point of the I-V curve that make the highest battery charging efficiency.
Current boost
Under most conditions, MPPT technology will "boost" the solar charge current through the solar module input power formula where MPPT Charging:
Power Into the controller (Pmax)=Power out of the controller (Pout), i.e., Iin x Vmp = Iout x Vout, assuming 100% efficiency.
If the solar module's maximum power voltage (Vmp) is greater than the battery voltage, the battery current must be proportionally greater than the
solar input current so that input and output power are balanced. The greater the difference between the Vmp and battery voltage, the greater the
current boost.
High Voltage Strings and Grid-Tie Modules
Another benefit of MPPT technology is the ability to charge batteries with solar arrays of higher nominal voltages. For example, a 12 Volt battery
bank may be charged with a 12-, 24-, 36-, or 48-Volt nominal off-grid solar array. Grid-tie solar modules may also be used as long as the solar array
open circuit voltage (Voc) rating will not exceed the maximum input voltage rating at worst-case (coldest) module temperature. The solar module
documentation should provide Voc vs. temperature data.
