4. Persediaan dan Pemasangan
4.1 Sistem Selesaiview
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 Sambungan Bateri
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:
| Model | Saiz Wayar | Kabel (mm²) | Nilai tork (maks) |
|---|---|---|---|
| 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. Arahan Operasi
5.1 Mod Pengecasan
The inverter supports four charging modes:
- Utiliti Pertama: Prioritizes utility power for charging.
- Solar First: Mengutamakan kuasa solar untuk pengecasan.
- Solar & Utility: Menggunakan kuasa solar dan utiliti untuk pengecasan.
- Battery & Solar: Charges from both battery and solar sources.
5.2 Mod Output
The inverter offers three output priority modes:
- Keutamaan PV: Solar power is the primary source for loads.
- Keutamaan Utiliti: Utility power is the primary source for loads.
- Keutamaan SBU (Solar-Bateri-Utiliti): 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 webtapak: Y&H Store
6. Penyelenggaraan
Penyelenggaraan tetap memastikan jangka hayat dan prestasi optimum penyongsang anda. Sentiasa putuskan sambungan semua punca kuasa sebelum melakukan sebarang penyelenggaraan.
- Pembersihan: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow. Use a dry cloth to clean the exterior.
- Sambungan: Periksa secara berkala semua sambungan elektrik untuk kesesakan dan tanda-tanda kakisan.
- Persekitaran: Ensure the installation environment remains within the specified operating temperature and humidity ranges.
7. Penyelesaian masalah
Bahagian ini menangani isu-isu biasa dan potensi penyelesaiannya.
- Ralat Tetapan: 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.
