4. Configuració

4.1 Entorn d'instal·lació

Install the inverter in a clean, dry, and well-ventilated area. Avoid direct sunlight, high temperatures, and excessive humidity. Ensure sufficient clearance around the unit for proper airflow.

4.2 Connexions de cablejat

Refer to the port diagram in Section 3 for connection points. Ensure all connections are secure and correctly polarized. Use appropriate cable gauges for all connections to prevent overheating and power loss.

• Connexió de la bateria: Connect the 48V battery bank to the Battery Input terminals. Observe correct polarity (+ to + and - to -).
• Entrada del panell solar: Connect your solar array to the Solar Panel Input terminals. Ensure the total open circuit voltage of the PV array does not exceed 500VDC.
• Entrada/Sortida de CA: Connect the grid AC power to the AC Input and your loads to the Main Output and Second Output terminals.
• Connexió paral·lel: For parallel operation (up to 9 units), connect the parallel communication cables and power balancing lines between the inverters.

4.4 Battery-less Operation

This inverter supports battery-less operation, allowing it to directly power loads from photovoltaic (PV) modules. In this mode, the inverter converts DC power from PV directly to AC power for homes or other loads. If PV generation is insufficient, the system can draw energy from the grid to ensure continuous power supply.

Image: Explanation of battery-free operation, detailing how the inverter can supply power without connecting batteries, directly converting DC power from PV modules to AC power for loads, and integrating with the grid when PV power is insufficient.

5.2 modes de càrrega

L'inversor admet quatre modes de càrrega:

1. Priority of the Mains Power Supply: If no mains power is available, the battery is charged using solar energy.
2. Prioritat solar: Charging with solar energy has priority. If no solar power is available, the battery is charged via the power grid.
3. Mixed Loading: Solar and mains power can charge the battery at the same time.
4. Només solar: The battery can only be recharged using solar energy.

5.3 Charge Output Working Modes

The inverter offers three charge output working modes:

1. Netz (Utility Priority - Default): The mains current has priority over the load.
2. Solar: Solar power has priority, then battery, then grid for power consumption.
3. SBU (Solar-Battery-Utility): Solar power has priority, then battery, then utility (grid) in order of priority.
