2.1 Valdiklio montavimas

Mount the charge controller vertically on a non-flammable surface in a well-ventilated area. Ensure adequate clearance around the unit for proper heat dissipation. Maintain a minimum clearance of 150mm (approximately 6 inches) above and below the controller for optimal airflow.

Figure 2.1: Mounting Clearance. This diagram illustrates the recommended minimum clearance of 150mm (6 inches) above and below the charge controller to ensure proper air circulation for cooling.

2.2 Laidų jungtys

Follow the wiring diagram carefully. Always connect the battery first, then the solar panels, and finally the DC load. Disconnect in the reverse order.

1. Prijunkite akumuliatorių: Connect the battery bank to the BAT+ and BAT- terminals. Ensure correct polarity.
2. Prijunkite saulės baterijas: Connect the solar panel array to the PV+ and PV- terminals. Observe correct polarity and ensure the open-circuit voltage of the solar array does not exceed the controller's maximum input voltage (150 V).
3. Prijunkite nuolatinės srovės apkrovą (neprivaloma): Connect your DC loads to the LOAD+ and LOAD- terminals.
4. Prijunkite temperatūros jutiklį (neprivaloma): If using, connect the external temperature sensor to the designated port for accurate battery temperature compensation.
5. Prijunkite keitiklį (neprivaloma): If an inverter is used, connect it directly to the battery bank, not through the load terminals of the controller.

It also illustrates the navigation flow through various parameters like Main Monitoring Page, Component Voltage, Charging Current, Battery Voltage, Battery Capacity, Load Current, Charging Capacity, Device Temperature, Discharging Capacity, Load Mode, and Abnormality Codes.

3.2 Akumuliatoriaus įkrovimas Stages

The MPPT charge controller employs advanced charging algorithms to optimize battery life and performance. The charging process typically involves several stages:

• Fast Charging (Bulk): Delivers maximum current to rapidly charge the battery.
• Sustaining Charging (Absorption): Palaiko pastovų tūrįtage to fully charge the battery without overcharging.
• Plaukiojantis įkrovimas: Reduces voltage to a lower level to maintain the battery at full charge and compensate for self-discharge.
• Equalizing Charging (for specific battery types): Periodically overcharges the battery at a controlled rate to balance cell voltagir užkirsti kelią sulfacijai.

3.3 Baterijos tipo pasirinkimas

The controller supports various battery types. It is crucial to select the correct battery type in the settings to ensure proper charging parameters and prevent damage to the battery. Options typically include:

• SLD: Sandari švino rūgšties baterija
• FLD: Open Lead-Acid Battery (Flooded)
• GEL: Gelio baterija
• LI: Ličio baterija
• VARTOTOJAS: User-defined parameters for custom battery types.

3.4 Bluetooth Module (Optional)
