4. Configuración e instalación

4.1 Diagrama de cableado

Refer to the electrical schematic for proper system wiring. Ensure all connections are secure and correctly polarized.

Figure 3: Electrical Schematic. This diagram shows the complete wiring for a solar inverter system, including solar panels, combiner box, DC/AC breakers, inverter, utility grid connection, and loads.

4.2 Conexión da batería

The inverter supports 12V and 24V battery configurations. It automatically detects the battery voltage and adjusts its output accordingly (2300W for 12V, 4200W for 24V). For 24V systems, connect two 12V batteries in series. For 12V systems, connect batteries in parallel if increasing capacity.

Figure 4: Battery Connection Options. This image illustrates how to connect batteries for 12V (parallel connection for 2300W output) and 24V (series connection for 4200W output) systems.

The inverter also supports lithium batteries and includes a BMS (Battery Management System) interface for monitoring and protection. Ensure the BMS is properly connected if using lithium batteries.

Figure 5: Communication Interfaces. This image highlights the dual communication interfaces for BMS (Battery Management System) and optional WiFi module, enabling remote monitoring and battery communication.

4.3 Startup and Shutdown Sequence

Secuencia de inicio:

1. Conecte a batería.
2. Acende o inversor.
3. Activate the protective switches for PV, Utility, and Loads.

Secuencia de apagado:

1. Deactivate the protective switches for Loads, Utility, and PV.
2. Apague o inversor.
3. Desconecta a batería.

Important Note: Inductive loads (e.g., motors, refrigerators) may require up to 3 times their rated power for startup. Ensure the inverter's capacity is sufficient to handle these surge loads. Exceeding the inverter's surge capacity can cause damage.

5. Funcionamento

5.1 Pantalla LCD e configuración

The inverter features an LED display that provides real-time system data and operating status. Use the function buttons below the display to navigate menus and configure settings. Settings include battery charging current, AC/solar charging priority, and charging current priority.

5.2 Modos de carga

O inversor ofrece catro modos de carga configurables:

• Prioridade solar: Solar power is prioritized for charging.
• Só solar: Only solar power is used for charging.
• Prioridade de servizos públicos: Utility grid power is prioritized for charging.
• Solar + Utility Hybrid: Combina enerxía solar e de servizos públicos para cargar.

5.3 Modos de saída

Three output modes are available to adapt to various application needs:

• Solar Priority (SUB): Solar power is prioritized for loads.
• Utility Priority (USB): Utility grid power is prioritized for loads.
• SBU: Solar, Battery, Utility priority.

Figure 6: Charging and Output Modes. This diagram visually explains the four available charging modes (Solar Charge, Utility Priority, Solar Priority, Hybrid Charge) and three load output modes (PV Priority, Utility Priority, SBU Priority).

5.4 Monitorización remota

The inverter supports remote monitoring via an optional WiFi/GPRS module (sold separately). This allows users to monitor system performance and status from a distance.

6. Mantemento

Un mantemento regular garante un rendemento óptimo e unha lonxevidade do seu inversor:

• Keep the inverter clean and free from dust. Use a dry cloth for cleaning.
• Asegúrese de que as aberturas de ventilación non estean bloqueadas.
• Comprobe periodicamente todas as conexións do cableado para comprobar se están ben apertadas e se presentan signos de corrosión.
• Monitor the battery status, especially if using lithium batteries with the BMS interface, to prevent overcharge or deep discharge.
• Inspect solar panels for dirt or damage that could reduce efficiency.

7 Solución de problemas

The LED display will show error codes if issues arise. Refer to the inverter's display for specific error codes to diagnose and resolve problems. Common issues and their potential solutions include:

• Sen potencia de saída: Check battery connections, DC/AC breakers, and inverter power switch.
• Vol. De batería baixatage: Ensure batteries are adequately charged. Check charging sources (solar, utility).
• Aviso de sobrecarga: Reduce the connected load. Inductive loads may cause temporary overloads during startup.
• Sobrequecemento: Ensure proper ventilation. Clean any dust from the inverter's vents.
• PV Input Error: Check solar panel connections and voltage. Ensure PV array voltage está dentro do intervalo especificado (55-500 V CC).
