• Elakkan cahaya matahari langsung, sumber haba dan kelembapan.

4.3 Sambungan Pendawaian

Semua pendawaian mesti mematuhi kod dan peraturan elektrik tempatan.

Figure 4.1: General Connection Diagram. This diagram illustrates how the inverter integrates with solar panels, an MPPT charge controller, battery bank, generator, utility grid, and household appliances.

a. DC Battery Connection:

• Connect the positive (+) terminal of the 48V battery bank to the red (+) terminal on the inverter.
• Connect the negative (-) terminal of the 48V battery bank to the black (-) terminal on the inverter.
• Use appropriate gauge cables for the current draw. Ensure connections are tight and secure.
• Install a DC circuit breaker or fuse between the battery bank and the inverter for protection.

b. AC Input Connection (Grid/Generator):

• Connect the 240V AC input source (utility grid or generator) to the AC input terminal block on the inverter.
• Ensure correct wiring for HOT1 and HOT2. This inverter requires a 240V AC input for its charging function and bypass.
• Install an AC circuit breaker for the input line.

c. AC Output Connection (Loads):

• Connect your 120V/240V AC loads to the AC output sockets or terminal block.
• The inverter provides split-phase output, allowing for both 120V and 240V loads.
• Ensure the total load does not exceed the inverter's capacity.

d. Grounding:

• Connect the inverter's ground terminal to a reliable earth ground. This is a critical safety step.

4.4 Kuasa Permulaan

• Periksa semula semua sambungan pendawaian untuk ketepatan dan keketatan.
• Ensure all circuit breakers are in the OFF position.
• First, turn ON the DC circuit breaker from the battery bank.
• Then, press the ON/OFF button on the inverter's front panel. The LCD display should illuminate.
• If using AC input, turn ON the AC input circuit breaker.
• Finally, turn ON the AC output circuit breakers to power your loads.

5. Mod Operasi

The inverter offers five distinct operating modes to suit various power management needs. These modes can be configured via the front panel controls.

1. AC/Line Priority Mode: In this mode, the inverter prioritizes AC input (utility or generator) to power the load and simultaneously charges the battery bank. If the AC input fails, the inverter automatically switches to battery power.
2. Mod Keutamaan Bateri: The inverter primarily uses battery power to supply the load. When the battery voltage drops below a set threshold, it switches to AC input (if available) to power the load and charge the batteries. Once batteries are sufficiently charged, it reverts to battery power. This mode includes low voltage restore and protect settings.
3. Mod ECO: This energy-saving mode puts the inverter into a low-power standby state when the load is less than 10% of its capacity. When the load increases above 10%, the inverter automatically activates and resumes normal operation.
4. Generator Mode: Designed for use with unstable generator AC input. The inverter regulates the incoming 240V AC from the generator, matches it to 60Hz, and provides a stable output voltage dalam julat operasi biasa.
5. Unattended Mode: Similar to Battery Priority, but with automatic recovery. When battery voltage is low, the inverter enters standby. It automatically restores normal inverter output once the battery voltage recovers (e.g., from solar charging), enabling fully automatic operation without manual intervention. This mode also features low voltage restore and protect settings.

6. Battery Settings

The inverter allows for customization of battery parameters to optimize charging and discharge cycles for different battery chemistries.

6.1 Pemilihan Jenis Bateri

The inverter supports various 48V battery types. Select the appropriate type via the control panel to ensure correct charging voltages and protection thresholds.

• Pre-set Options: SLA, AGM, GEL, Li-ion, Flooded.
• Customize Option: For specific battery chemistries like LiFePO4, you can use the 'Customize' setting to manually input charge voltage and other parameters. Refer to your battery manufacturer's specifications for recommended values.

6.2 Adjustable Charging Current

The maximum AC charging current can be adjusted from 0A to 35A. This allows you to match the charging rate to your battery bank's capacity and manufacturer recommendations.

• Menetapkan Julat: 0A - 35A.
• Disable Charging: Setting the current to 0A will disable the AC charging function.

7. Penyelenggaraan

Penyelenggaraan berkala memastikan jangka hayat dan operasi inverter anda yang boleh dipercayai.

• Pembersihan: Periodically clean the exterior of the inverter and ensure ventilation openings are free from dust and debris. Use a dry cloth; do not use liquid cleaners.
• Pemeriksaan Sambungan: Annually inspect all electrical connections (DC and AC) for tightness and corrosion. Loose connections can cause overheating and damage.
• Pemeriksaan Bateri: For lead-acid batteries, check electrolyte levels and terminal corrosion as per battery manufacturer guidelines.
• Pemeriksaan Alam Sekitar: Pastikan persekitaran pemasangan kekal dalam had suhu dan kelembapan yang ditetapkan.
