- Measure the actual battery voltage with a precise multimeter.
- Use "PV▲" or "BAT▼" to adjust the displayed voltage on the controller to match the multimeter reading.
- Press "SET/Ⓞ" to confirm and save the calibration.
4.4 3-Stage PWM Charging
O controlador emprega un sistema de 3 segundostage charging algorithm to optimize battery charging and extend battery life.
Figure 7: Explanation of the 3-stage PWM charging process.
- Carga masiva: The battery is charged at maximum current until the voltage alcanza o volume de carga impulsiva configuradotage.
- Aumentar a carga: The battery continues to charge at the configured boost charging voltage until it reaches a full charge state, with the charge current gradually decreasing.
- Carga flotante: The controller reduces the battery voltage by lowering the charging current, maintaining the battery at a floating charging voltage to keep it fully charged.
4.5 Configure Load Enable Duration
The load output can be configured for continuous operation or controlled by solar light and time settings.
To configure load duration:
- Press and hold "SET/Ⓞ" to enter the load mode setting.
- Use "PV▲" or "BAT▼" to select the desired mode:
