Thank you very much for using our product! We will offer you the permanent and reliable service for your solar system! The manual gives important recommendations for installing and using the MPPT controller. Please read the manual carefully and thoroughly before using this product.
When the circumstances change, the working point of solar panels deviate from the maximum power point, MCU will adjust the solar panels working point based on MPPT calculation to make the solar panels back to the maximum power point again(refer to Chapter 2.4 about MPPT technology introduction).

The controller uses Buck conversion circuit and MCU technology to track the maximum power point to implement the maximum output power of solar panels in different illumination intensity and temperature. The MPPT algorithm increases efficiency of your PV system and decreases the quantity of solar panels.

SMPPT Installation & Operation Manual Version 1.0 battery and prevents battery from leaking gas, and this can increase the lifetime of battery. Float Charge: The battery is at saturation state, and the controller charges the battery at a trickle current to make the battery voltage fixed at the settled float charging voltage (this voltage has temperature compensation).
Load key(Load key chapter 5.2.2). 2.4 MPPT technology Instructions Solar panels are nonlinear materials, and the output power is mainly affected by illumination intensity, solar panels temperature and load impedance. When the illumination intensity and solar panels temperature are fixed, the output power of solar panels is only affected by load impedance.

Compare working point A & B, it is easy to find using MPPT controller can increase the using efficiency of solar panels. Compared to normal controller, MPPT controller can generate more power.
SMPPT Installation & Operation Manual Version 1.0 Figure 2-5: Voltage-Power Curve 3. PV System Planning Reference 3.1 System Voltage The common system voltage of solar system has 3 types: 12V, 24V and 48V. The higher the system voltage, the more power the system can handle. In reality application, user should consider the load power, and the voltage scope permitted by load, and then confirms which system voltage you should use.
