4. Setup and Installation
Proper installation is critical for the safe and efficient operation of your Ampinvt inverter. Follow these steps carefully.
4.1 Physical Placement
- Install the inverter in a dry, well-ventilated area, away from direct sunlight and heat sources.
- Ensure sufficient clearance around the unit for proper airflow, especially around the cooling vents.
- Mount the inverter securely on a stable surface.
Figure 4.1: Product dimensions for installation planning. The inverter measures 650mm (length) x 300mm (width) x 185mm (height) and weighs 30.4kg.
4.2 Wiring Connections
All wiring should be performed by a qualified electrician. Ensure all power sources are disconnected before making any connections.
- Battery Connection: Connect the DC battery cables to the inverter's battery terminals. Ensure correct polarity (red to positive, black to negative).
- AC Input Connection: Connect the AC input power source (e.g., grid or generator) to the AC INPUT terminal block.
- AC Output Connection: Connect your AC loads to the AC OUTPUT terminal block or directly to the AC output sockets.
- Grounding: Connect the inverter to an appropriate earth ground.

5. Operating Instructions
The inverter features an LCD display for monitoring and configuration, along with several working modes to suit different power requirements.
5.1 LCD Display and Controls
The LCD provides real-time data and allows adjustment of settings. Use the ESC, Up, Down, and Enter/Menu buttons to navigate and configure the inverter.

5.2 Working Modes
The inverter offers five distinct working modes, configurable via the LCD display:
- AC Input Priority Mode: Prioritizes utility power (110V AC). If utility power fails, the inverter switches to battery power. When utility power returns, it switches back.
- Battery Priority Mode: Prioritizes battery power. If battery voltage drops below a set threshold, it switches to utility power. Once the battery is sufficiently charged, it reverts to battery power.
- ECO Mode: For energy saving. If the load is less than 10%, the inverter enters sleep mode and stops output. It automatically restarts normal inversion when the load exceeds 10%.
- Generator Mode: Designed for use with unstable AC voltage sources, such as generators. The inverter's AVR regulator stabilizes the output voltage.
- Unattended Mode: When battery voltage is low, the inverter enters a standby (power-saving) state. It automatically restores normal output when the battery voltage recovers (e.g., from solar charging), enabling fully automatic operation without supervision.
5.3 Adjustable Settings
- AC Charging Voltage & Current: Adjustable charging voltage (13.4-14.9VDC for 12V systems) and current (0-35A) for various battery types.
- Low Voltage Protection & Recovery: Customizable voltage thresholds for low voltage protection and recovery to prevent battery over-discharge.
- Battery Type Setting: Compatible with Sealed, Gel, AGM, Flooded, and Lithium batteries. Ensure the correct battery type is selected for optimal charging and discharge cycles.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Periodically clean the exterior of the inverter and ensure cooling vents are free from dust and debris. Use a dry cloth.
- Connections: Regularly check all electrical connections (battery, AC input, AC output) for tightness and corrosion. Tighten any loose connections.
- Battery Health: Monitor battery voltage and health according to battery manufacturer guidelines. Ensure proper charging cycles.
- Environment: Maintain the operating environment within specified temperature and humidity ranges.
7. Troubleshooting
This section provides solutions to common issues. For complex problems, contact qualified service personnel.
| Problem | Possible Cause | Solution |
|---|---|---|
| No AC Output | Low battery voltage, overload, short circuit, high temperature. | Check battery charge, reduce load, check for short circuits, allow inverter to cool. |
| Inverter not turning on | Loose battery connections, blown fuse, battery completely discharged. | Check battery connections, replace fuse, charge battery. |
| AC Input not charging battery | AC input voltage out of range, AC input priority mode not selected, charger fault. | Verify AC input voltage, select AC Input Priority mode, contact support if charger fault persists. |
