4.4 Adjustable Charging Current
The maximum charging current can be adjusted from 0-35A. Setting the value to 0A will disable the charging function. This setting allows for optimization based on battery capacity and type.
5. Mod Operasi
The OAE FT-2000W12V inverter offers five distinct operating modes to suit various power management needs:
- AC/Line Priority Mode: In this mode, the inverter prioritizes AC utility power as the primary input. It provides AC output to loads and automatically charges the connected battery. If AC utility power fails, the inverter seamlessly switches to battery power.
- Mod Keutamaan Bateri: This mode prioritizes battery power supply. The inverter will draw power from the battery to supply loads. Upon reaching a low voltage protection threshold, it will transfer to AC utility power. Once the battery is sufficiently recharged, it will revert to battery power.
- Mod ECO: Designed for energy saving, the inverter enters a sleep state and stops output when the load is less than 10% of its capacity. When the load exceeds 10%, it automatically reactivates and resumes normal inversion.
- Generator Mode: This mode is used when an unstable generator (120V) is connected to the inverter's AC input. The inverter's built-in AVR (Automatic Voltage Regulator) stabilizes the input, automatically matching 50Hz/60Hz frequency, and regulates the output voltage dalam julat operasi biasa.
- Unattended Mode: Apabila bateri voltage drops to a low level, the inverter enters a standby (power-saving) state. It will automatically restore normal inverter output once the battery voltage recovers to a user-defined value (e.g., through solar charging), enabling fully automatic operation without manual intervention.
6. Penyelenggaraan
Penyelenggaraan berkala memastikan jangka hayat dan prestasi optimum inverter anda:
- Pastikan inverter bersih dan bebas daripada habuk. Gunakan kain kering untuk pembersihan.
- Pastikan bukaan pengudaraan tidak disekat.
- Periksa semua sambungan elektrik secara berkala untuk kesesakan dan kakisan.
- Inspect battery terminals for corrosion and clean if necessary.
- Monitor the inverter's display for any error codes or warnings.
7. Penyelesaian masalah
This section provides guidance for common issues. For problems not listed here, contact customer support.
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Penyongsang tidak dihidupkan | Tiada input DC daripada bateri; Voltan bateritage too low; Loose connections. | Check battery connections; Charge battery; Verify battery voltage berada dalam julat operasi. |
| Tiada output AC | Overload; Short circuit; Over temperature; AC output breaker tripped. | Reduce load; Check for short circuits; Allow inverter to cool; Reset AC output breaker. |
| Bateri tidak dicas | AC input not present; Charging current set to 0A; Battery fault. | Verify AC input connection; Adjust charging current setting; Check battery health. |
| Perlindungan Lebihan Diaktifkan | Beban yang disambungkan melebihi kapasiti penyongsang. | Reduce the total load connected to the inverter. The inverter can sustain 110%-120% of output for 30s before bypassing, and over 160% for 303ms. |
Penting: Jangan bebankan inverter secara berlebihan. Pastikan jumlah kuasatage of connected appliances does not exceed the inverter's rated capacity.
