4. Konfigurazioa eta instalazioa
4.1 Kableatutako konexioak
Carefully connect the solar panels, battery bank, AC input (grid), and AC output (loads) to the designated terminals on the inverter. Ensure all connections are secure and correctly polarized. Refer to the wiring diagram in Figure 3 for port locations.
4.2 Eragiketa Paraleloa
The DATOUBOSS 11KW Hybrid Solar Inverter supports parallel operation of up to 9 units to increase total power output. Follow the specific communication and power wiring diagrams provided in the full installation guide for multi-unit setups.

4.3 Hasierako konfigurazioa
Upon initial power-up, use the LCD and function keys to configure essential settings. This includes setting the input voltage range suitable for your household appliances or personal computers, and defining the AC/solar charger priority.
5. Funtzionamendu moduak
The inverter offers various operating modes to optimize power usage and battery charging.
5.1 Kargatzeko moduak
There are four distinct charging modes available:
- Priority of the Mains Power Supply: If mains power is available, the battery is charged using solar energy.
- Eguzki-lehentasuna: Charging with solar energy has priority. If no solar power is available, the battery is charged via the power grid.
- Mixed Loading: Solar and mains power can charge the battery at the same time.
- Eguzkia bakarrik: The battery can only be recharged using solar energy.
5.2 Charge Output Working Modes
Three charge output working modes determine the power source priority for connected loads:
- Netz (Utility Priority): The mains current has priority over the load (default).
- Solar (Solar Priority): Solar power has priority, followed by battery, then grid power for the consumer.
- SBU (Eguzki-Bateria-Erabilgarritasuna): Solar power is prioritized, then battery. If battery voltage drops below a set point, the grid supplies power.

6. Mantentzea
- Ohiko garbiketa: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow and prevent overheating.
- Bateriaren kudeaketa: The inverter's integrated features help manage battery charging and discharging cycles to prolong battery life. Ensure batteries are maintained according to their manufacturer's guidelines.
- Konexioaren egiaztapenak: Aldian-aldian ikuskatu konexio elektriko guztiak estutasuna eta korrosio zantzurik dagoen egiaztatzeko.
- Firmware eguneraketak: Egiaztatu fabrikatzailearena webwebgunea errendimendu hobea lortzeko edo funtzio berriak lortzeko firmware eguneratze eskuragarri dauden ikusteko.
7. Arazoak
