Installation Steps (General):

1. Mounting: Choose a suitable location for mounting the inverter. It should be indoors, well-ventilated, and protected from direct sunlight and moisture. Ensure sufficient clearance for air circulation.
2. Battery Connection: Connect the battery bank to the inverter's battery terminals. Ensure correct polarity (+ to + and - to -). Use appropriate cable gauges.
3. AC Input Connection (Utility/Generator): Connect the utility grid or generator AC input to the designated AC input terminals on the inverter.
4. AC Output Connection (Loads): Connect your household loads or distribution panel to the AC output terminals of the inverter.
5. PV Input Connection (Solar Panels): Connect the solar panel array to the PV input terminals. Verify correct voltage and current ratings.
6. Grounding: Ensure the inverter is properly grounded according to local electrical codes.
7. Initial Power-Up: Follow the specific power-up sequence outlined in the full manual (typically battery first, then solar, then AC input).

5. Operating Modes

The HYG 5532 inverter supports multiple operating and charging modes to optimize energy usage based on your specific needs and available power sources.

Programmable Operation Modes:

• Grid-tie: The inverter operates in parallel with the utility grid, feeding excess solar power back into the grid.
• Off-grid: The inverter operates independently from the utility grid, providing power from solar and/or batteries to connected loads.
• Grid-tie with backup: Combines grid-tie functionality with battery backup for uninterrupted power during grid outages.

Four Charging Modes:

The inverter offers four distinct charging modes to manage battery charging from solar, utility, or a combination of both.

Image 5.1: Visual representation of the four charging modes: Solar Only, Solar Priority, Mains Priority, and Hybrid Charge.

• Solar Only: Solar energy is the sole charging source. This mode is suitable for areas with abundant solar resources where utility power is unavailable or not needed.
• Solar Priority: Solar energy charges the battery first. Utility power charges the battery only when solar energy is insufficient or unavailable. Ideal for areas with stable grid and high electricity prices.
• Mains Priority: Utility power charges the battery first. Solar energy charges the battery only when utility power is unavailable.
• Hybrid Charge: Both solar energy and utility power charge the battery simultaneously. This mode is suitable for areas with unstable power grids, ensuring continuous backup power.

6. LCD Display and Operation

The inverter features an intuitive LCD display and operation buttons for monitoring system status and configuring settings. The display provides real-time information on input/output voltage, current, frequency, battery status, and operational mode.

Operation Buttons:

The control panel, visible in Image 3.1, includes buttons for navigation and selection:

• ESC: Exit current menu or cancel selection.
• UP/DOWN: Navigate through menu options or adjust values.
• ON/OFF: Power on/off the inverter.
• ENTER: Confirm selection or enter a submenu.

Detailed instructions for navigating the LCD menu and configuring specific parameters (e.g., battery type, charging current, output voltage range) are provided in the comprehensive user manual.

7. Parallel Operation

For higher power requirements, the 10KW and 15KW models of this inverter series support parallel operation, allowing up to 6 units to work together. The HYG 5532 (5.5KW) model does not support parallel operation.

Parallel operation requires specific wiring and configuration. Refer to the detailed instructions in the full user manual for proper setup of parallel systems.

8. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter. Always disconnect all power sources before performing any maintenance.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris.
• Connections: Annually inspect all electrical connections (battery, solar, AC input/output) for tightness and signs of corrosion. Tighten any loose connections.
• Environment: Ensure the installation environment remains within the specified temperature and humidity ranges.
• Battery Inspection: If using lead-acid batteries, check electrolyte levels and terminal conditions as per battery manufacturer guidelines.

9. Troubleshooting

If you encounter issues with your inverter, refer to the following general troubleshooting steps. For complex problems, contact customer support.

• No Power Output: Check battery connections, AC input breaker, and inverter's ON/OFF switch. Verify battery voltage is within operating range.
