4. Konfigurazioa eta instalazioa
4.1 Sistema amaituview
The hybrid power system integrates solar power, a generator or utility grid, and a battery to supply power to home appliances. The inverter manages the power flow between these sources.

4.2 Bateriaren konexioa
The inverter is compatible with AGM, GEL, Flooded Lead-Acid, and Lithium batteries. For Lithium batteries, settings may need to be configured via the "User-Defined" option. Always use a circuit breaker between the battery and the inverter.

Recommended Battery Cable Size:
| Eredua | Hariaren Tamaina | Kablea (mm²) | Momentuaren balioa (gehienez) |
|---|---|---|---|
| 3.6KW/4.2KW/6.2KW | 1 x 2AWG | 25 | 2 Nm |
4.3 AC Output Considerations
This inverter provides a single-phase 230V AC output. It does not provide 110V AC output directly. For 110V/120V US home appliances, a step-down converter (not included) is required to convert the 220V/240V AC power to 110V/120V AC power.
5. Funtzionamendu-argibideak
5.1 Kargatzeko moduak
The inverter supports four charging modes:
- Utility First: Prioritizes utility power for charging.
- Eguzki-energia lehenengo: Eguzki-energia lehenesten du kargatzeko.
- Solar & Utility: Eguzki-energia eta zerbitzu-energia erabiltzen ditu kargatzeko.
- Battery & Solar: Charges from both battery and solar sources.
5.2 Irteera moduak
The inverter offers three output priority modes:
- PV Priority: Solar power is the primary source for loads.
- Erabilgarritasun Lehentasuna: Utility power is the primary source for loads.
- SBU Lehentasuna (Eguzki-Bateria-Erabilgarritasuna): Solar power is used first, then battery power, and finally utility power as a backup.

5.3 WIFI Communication (Optional)
An optional WIFI module allows monitoring the inverter's working status and adjusting parameters remotely via a mobile phone application. The WIFI module is not included in the standard package.

For more details on the WIFI module and its setup, please refer to the specific instructions provided with the module or visit the manufacturer's webgunea: Y&H Store
6. Mantentzea
Mantentze-lan erregularrak zure inbertsorearen iraupena eta errendimendu optimoa bermatzen ditu. Deskonektatu beti energia-iturri guztiak edozein mantentze-lan egin aurretik.
- Garbiketa: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow. Use a dry cloth to clean the exterior.
- Konexioak: Aldian-aldian egiaztatu konexio elektriko guztiak estutasuna eta korrosio zantzurik dagoen ikusteko.
- Ingurumena: Ziurtatu instalazio-ingurunea zehaztutako funtzionamendu-tenperatura eta hezetasun-tarteen barruan mantentzen dela.
7. Arazoak
Atal honek arazo ohikoenak eta haien irtenbide posibleak jorratzen ditu.
- Ezarpen-errorea: If a setting error occurs, use the one-click restore function to revert to default settings. This can prevent potential machine damage.
- Specific Setting Behavior: Note that if item 37 is set to "hyd" (hybrid mode), item 01 will revert to SUB (Solar-Utility-Battery) mode instead of SBU (Solar-Battery-Utility) mode. This is expected behavior for this specific configuration.
