1. Solar Power Input: Connect your solar panels to the PV input (9) on the inverter. Ensure the maximum PV input voltage (150VDC) and power ratings are not exceeded.
2. AC Input (Utility/Generator): Connect the mains utility power or a generator to the AC input (7) of the inverter. This serves as a backup power source.
3. Battery Connection: Connect external battery packs to the Battery input (10). Ensure the correct DC input voltage (12V for AOH-1KW, 24V for AOH-1.5KW) is used. The charging voltage is adjustable.
4. AC Output: Connect your home appliances (e.g., refrigerator, laptop, lights, TV) to the AC output (8) or output receptacles (12) of the inverter.
5. Circuit Breaker: Ensure the circuit breaker (11) is accessible and correctly rated for your system.

Safety Warning: Always ensure all power sources are disconnected before making any electrical connections. Incorrect wiring can cause severe damage to the inverter, batteries, and connected appliances, and poses a risk of electric shock.

6. Operating Instructions

6.1 Powering On/Off

1. Ensure all connections are secure.
2. Turn on the power on/off switch (6).
3. The LCD display (1) will illuminate, and the status indicator (2) will show the current operating mode.

6.2 LCD Settings and Configuration

The inverter features a configurable LCD display and function buttons (5) to adjust various parameters:

• Input Voltage Range: Adjust the acceptable AC input voltage range for home appliances or personal computers.
• Battery Charging Current: Set the battery charging current based on your battery type and capacity. The maximum combined charging current (AC + Solar) is 80A.
• AC/Solar Charger Priority: Configure whether the inverter prioritizes charging from AC (utility/generator) or solar power.

Refer to the detailed instructions in the full product manual (if available) for specific navigation and adjustment procedures using the function buttons.

6.3 Cold Start Function

The inverter supports a cold start function, allowing it to power on directly from batteries even without an AC input or solar power, useful in off-grid scenarios.

7. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your inverter.

• Cleaning: Keep the inverter clean and free from dust. Use a dry cloth to wipe the exterior. Ensure ventilation openings are not blocked.
• Connection Checks: Periodically inspect all electrical connections (solar, battery, AC input/output) to ensure they are tight and free from corrosion.
• Ventilation: Ensure the inverter is installed in a well-ventilated area to prevent overheating. Do not obstruct the cooling fans.
• Environmental Conditions: Operate the inverter within the specified operating temperature range (-10°C to 50°C). Avoid exposure to direct sunlight, moisture, and corrosive substances.

8. Troubleshooting

This section addresses common questions and issues you might encounter.

• Inverter not turning on: Check battery connections and voltage. Ensure the power switch is in the 'ON' position.
• No AC output: Verify input sources (solar, AC utility/generator) are active. Check for overload or short circuit conditions indicated by the fault indicator (4).
• Battery not charging: Ensure solar panels are receiving adequate sunlight and are correctly connected to the PV input. Check AC input if AC charging is prioritized. Verify battery charging current settings.
• Can it work without batteries? No, this hybrid inverter requires batteries for operation.
• Does it feed power to the grid? No, this is an off-grid inverter and is not designed to sell electricity back to the grid.
• What is the hybrid function? The hybrid function means it's primarily an off-grid inverter that can also utilize the grid as a backup power source to charge batteries or supply loads, but it does not have grid-tie capabilities for selling electricity.
• Does it support parallel operation? No, this model does not support parallel connection for increased power output.

9. User Tips

• Battery Voltage: Always ensure you are using the correct battery voltage for your inverter model: 12V for AOH-1KW and 24V for AOH-1.5KW. Mismatched voltage can damage the unit.
• PV Input Limits: Pay close attention to the maximum PV input voltage (150VDC) and maximum PV array power (600W for 1KW, 1200W for 1.5KW) to prevent damage to the MPPT controller.
• Charging Current: The maximum combined charging current from AC and solar is 80A. Configure your battery charging current settings appropriately to optimize battery health and charging speed.
• Off-Grid Use: Remember that this is an off-grid inverter. While it can use grid power as a backup, its primary function is independent power generation.
• No Wi-Fi: This model does not include Wi-Fi connectivity for remote monitoring or control.
