8. Maximum Power Point Tracking (MPPT) Technology
Due to the nonlinear characteristics of solar arrays, there is a unique maximum energy output point (Max Power Point) on their curve. Traditional controllers (with switch charging or PWM charging) cannot charge the battery at this maximum power point, thus failing to obtain the maximum available energy from the PV array.
EPEVER's MPPT algorithm continuously compares and adjusts operating points to locate the array's maximum power point. This tracking process is fully automatic and requires no user adjustment. MPPT technology "boosts" the battery charge current by tracking the MPP. Assuming 100% conversion efficiency, the input power (PPV) equals the output power (PBat).
Normally, the PV array's maximum power point voltage (VMpp) is always higher than the battery voltage (VBat). Due to energy conservation, the battery current (IBat) is always higher than the PV current (IPV). The greater the difference between VMpp and VBat, the greater the difference between IPV and IBat. A larger difference between the array and the battery can decrease system conversion efficiency, highlighting the importance of the controller's conversion efficiency in the PV system.
MPPT controllers can increase efficiency by 20%-30% compared to PWM controllers.
In real-world applications, PV panels may exhibit multiple local maximum power points due to shading from clouds, trees, or snow. However, there is only one true global Maximum Power Point. The EPEVER MPPT algorithm is designed to quickly and accurately track this real MPP, improving PV array utilization and preventing energy waste.
9. Battery Charging Stages
The controller employs a three-stage battery charging algorithm: Bulk Charging, Constant Charging, and Float Charging. This method effectively prolongs battery lifespan and significantly improves system performance.
A) Bulk Charging:
When the battery voltage has not reached the constant voltage (Equalize or Boost Charging Voltage), the controller operates in constant current mode, delivering its maximum current (MPPT Charging) to the batteries.
B) Constant Charging:
Once the battery voltage reaches the constant voltage set point, the controller switches to constant charging mode. MPPT charging stops, and the charging current gradually decreases. This stage includes two phases: Equalize Charging and Boost Charging. These are not repeated in a single full charge cycle. Equalized charging typically occurs on the 28th of each month.
- Boost Charging: The default duration is 2 hours. Users can adjust this time and preset value. The system switches to float charging when the duration is met.
- Equalize Charging: Some battery types benefit from equalizing charging to stir electrolytes, balance voltage, and complete chemical reactions. This increases battery voltage above the standard complement voltage, gasifying the battery electrolyte. If automatically controlled, the equalizing charging time is 120 minutes. Equalize and boost charges are not performed constantly to avoid excessive gas precipitation or overheating.
WARNING (Equalize Charging):
Explosive Risk! Equalizing flooded batteries produces explosive gases; ensure good ventilation of the battery box.
CAUTION (Equalize Charging):
- Equipment damage! Equalization may increase battery voltage to levels that damage sensitive DC loads. Verify load's allowable input voltages.
- Over-charging and excessive gas precipitation can damage battery plates. Review specific requirements of your battery.
- The controller accumulates time when battery voltage equals the set value. If not adjusted, it equalizes charging based on internal timing.
C) Float Charging:
After constant charging, the controller reduces battery voltage to the float charging preset voltage by lowering the charging current. During this stage, the battery is maintained in a fully charged state. Loads can draw almost all power from the solar panel. If load power exceeds solar array power, the controller will no longer maintain float charging. If battery voltage drops below the boost voltage reconnect voltage, the system exits float charging and re-enters bulk charging.

| 11 | Overload Protection | Controller cuts off output after delay if load current exceeds 1.05x rating. Attempts 5 auto-recoveries (5, 10, 15, 20, 25s delays). To restart: press Load button, restart controller, or wait for night-to-day change (>3h). |
| 12 | Device Overheating | Controller stops working if internal temperature > 85°C, resumes below 75°C. |
| 13 | TVS High Voltage Transients | Internal TVS protects against high-voltage surge pulses with less energy. For frequent lightning, install external surge arrester. |
Note: When the controller's internal temperature reaches 81°C, the charging power automatically reduces (5%, 10%, 20%, 40% for each 1°C increase). Charging stops at 85°C and resumes below 75°C.
