2. Safety Information

Always adhere to the following safety precautions to prevent injury and damage to the inverter:

• Ensure all connections are secure and correctly polarized before powering on the unit.
• Do not attempt to disassemble or repair the inverter yourself. Refer to qualified personnel for servicing.
• Install the inverter in a well-ventilated area, away from flammable materials and direct sunlight.
• Verify that the input voltage from solar panels and batteries is within the specified range.
• This inverter outputs 220/230/240V AC. It is not designed for direct 110V AC output. A step-down converter (not included) is required for 110/120V appliances.
• Avoid installing the inverter near bedrooms due to potential fan noise (50-70 dB).

3.2 Wiring Connections

Refer to the wiring diagram below for correct connection of solar panels, batteries, and AC loads. Ensure all cables are of appropriate gauge and connections are tight.

Figure 3.2: Wiring diagram illustrating connections for generator/mains power, AC load, 24V battery, and solar panels. Recommended cable sizes are 12AWG for AC input/output and 16AWG for PV input. Battery wire size 4AWG.

• Solar Panel Connection: Max PV input power is 3000W. Voltage range: 55-450Vdc. Max. PV Input VOC: 450V DC. Starting voltage >60V. Recommended PV cable size: 16AWG. It is recommended to connect solar panels in series.
• Battery Connection: Compatible with 24V Lead-Acid (Seal, AGM, Gel, Flooded) and Lithium batteries. Ensure correct polarity. Battery wire size: 4AWG.
• AC Input/Output: Nominal Input Frequency: 50/60Hz. Output Power: 3000W, surge Capacity: 6000W. Max AC Input Voltage: 300Vac. Charging Current: 60A. Suggested cable: 12AWG. Recommended breaker: 32A.
• Load Connection: The inverter provides a single phase/hot leg 230V output. For 110/120V US home appliance equipment, a separate converter (not included) is required to step down the voltage.

4.2 Charging Modes

The inverter supports four charging modes:

• Only Solar (OSO): Prioritizes solar power for charging.
• Mains First (CSO): Prioritizes utility power for charging.
• Solar First (SNU): Prioritizes solar power, then utility power for charging.
• Mains & Solar Hybrid (SNU Default): Utilizes both mains and solar for charging.

4.3 Output Modes

Three output modes are available to ensure uninterrupted power supply:

• Solar First (SUB Default): Prioritizes solar power for loads.
• Mains First (USB): Prioritizes utility power for loads.
• SBU Priority: Prioritizes solar, then battery, then utility for loads.

5. Maintenance

Regular maintenance ensures the longevity and efficient operation of your inverter:

• Keep the inverter clean and free from dust. Use a dry cloth for cleaning.
• Ensure proper ventilation around the unit. Do not block air vents.
• Periodically check all electrical connections for tightness and signs of corrosion.
• Monitor the LCD display for any error codes or unusual readings.
• Inspect cables for any damage or wear. Replace damaged cables immediately.

6. Troubleshooting

If you encounter issues with your Y&H Solar Hybrid Inverter, refer to the following common troubleshooting steps:

• No Power Output: Check AC input and battery connections. Ensure solar panels are receiving sufficient sunlight and producing voltage within the specified range. Verify circuit breakers are not tripped.
• Inverter Shutting Down: This could indicate an overload, over-temperature, or battery low voltage condition. Reduce the load, ensure adequate ventilation, or check battery charge level.
• Fluctuating AC Output: Check all wiring connections for looseness. Ensure stable input from both solar and utility sources. If the issue persists, contact customer support.
• Error Codes on LCD: Consult the full user guide (PDF link provided in product details) for specific error code definitions and resolutions.

For complex issues or if troubleshooting steps do not resolve the problem, please contact Y&H customer support.
