3. Configuració i instal·lació

Una instal·lació correcta és crucial per al funcionament segur i eficient del vostre controlador de càrrega solar. Seguiu aquestes pautes generals:

1. Lloc de muntatge: Choose a cool, dry, and well-ventilated indoor location. Avoid direct sunlight, high temperatures, and moisture. Ensure sufficient clearance around the controller for heat dissipation.
2. Superfície de muntatge: Mount the controller vertically on a non-flammable surface using appropriate screws. The die-cast aluminum design aids in heat dissipation, but good airflow is still essential.
3. Seqüència de cablejat: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order. Ensure correct polarity for all connections.
4. Mida del cable: Use appropriately sized cables for all connections (solar, battery, load) to minimize voltage drop and ensure safety. Refer to local electrical codes and the controller's specifications for recommended wire gauges.
5. Posada a terra: Ensure the controller is properly grounded according to local regulations.

For detailed wiring instructions, refer to the "Wiring Diagram" section below.

4. Esquema de cablejat

The following diagram illustrates the typical wiring connections for the EPEVER MPPT Solar Charge Controller within a solar power system. Ensure all connections are secure and correctly polarized.

Figure 4.1: Wiring connections for the solar charge controller, showing connections to solar panels, battery, inverter, and various loads. The MT50 remote meter and PC/APP monitoring connections are also depicted.

• Connexió de la bateria: Connect the battery to the controller's battery terminals first. Observe correct polarity (+ to + and - to -).
• Connexió del panell solar: Connect the solar panel array to the controller's PV terminals. Ensure correct polarity.
• Connexió de càrrega: Connect your DC loads (e.g., lights, small appliances) to the controller's load terminals.
• Connexions opcionals:
  • MT50 Remote Meter: Connect the MT50 to the controller via the RS485 port for remote monitoring and parameter setting.
  • PC/APP Monitoring: Use the RS485 to USB cable (and eBox for APP) to connect the controller to a PC or smartphone for advanced monitoring and data logging.
  • Temperature Sensor (RTS): Connect the RTS to the designated port for accurate battery temperature compensation.

5. Instruccions de funcionament

Once installed, the EPEVER MPPT Solar Charge Controller operates largely automatically. However, understanding its indicators and settings is beneficial for optimal system management.

5.1. Engegada inicial

After connecting the battery, the controller will power on and display system information. Connect the solar panels, and the controller will begin charging the battery if sufficient solar power is available.

5.2. Using the MT50 Remote Meter

The MT50 remote meter provides real-time data and allows for parameter adjustments. Connect it to the controller's RS485 port. The display shows charging status, battery voltage, PV voltage, and load status. Use the buttons to navigate menus and modify settings such as battery type, load control mode, and charging parameters.

5.3. Load Control Modes

The controller offers various load control modes, configurable via the MT50 or PC software:

• Control manual: Turn the load ON or OFF manually.
• Llum ON/OFF: Load turns ON at dusk and OFF at dawn.
• Light ON + Timer: Load turns ON at dusk and stays ON for a set duration.
• Control de temps: Load turns ON and OFF at specific times.

5.4. Selecció del tipus de bateria

Select the correct battery type (Sealed, Gel, Flooded, or User-defined) to ensure proper charging algorithms and prolong battery life. Incorrect settings can damage your batteries.

6. Manteniment

Regular maintenance helps ensure the longevity and optimal performance of your EPEVER MPPT Solar Charge Controller and the entire solar system.
