2. Safety Instructions
Please observe the following safety precautions during installation, operation, and maintenance of the inverter and battery system. Failure to comply may result in electric shock, fire, or severe injury.
- Installation must be performed by qualified personnel.
- Ensure all wiring is correctly sized and properly insulated.
- Disconnect all power sources (PV, battery, AC grid) before performing any maintenance or wiring.
- Do not disassemble the inverter or battery. There are no user-serviceable parts inside.
- Keep the system away from flammable materials, moisture, and direct sunlight.
- Ensure adequate ventilation around the inverter and batteries to prevent overheating.
- Wear appropriate personal protective equipment (PPE), including insulated gloves and eye protection, when working with the system.
- Verify correct polarity for all DC connections.
- Do not connect the inverter to a public utility grid without proper anti-islanding protection and local utility approval.
3. Installation and Wiring
3.1 Site Selection
Choose a cool, dry, and well-ventilated location for installation. Avoid areas with excessive dust, corrosive gases, or high humidity. The inverter should be mounted vertically on a sturdy surface.
3.2 System Connection Diagram
The SUNGOLDPOWER inverter supports various configurations including split-phase (120V/240V) and single-phase (120V) output, as well as parallel operation. The following diagrams illustrate typical system connections.

4.3 Battery Management
The inverter is compatible with various 48V battery types, including AGM/Sealed, Gel, Flooded, and Lithium. A User Mode is available for custom battery settings. The system supports battery-free operation. When lithium batteries are dormant, both mains power and photovoltaics can activate them via the inverter.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar inverter system.
- Cleaning: Periodically clean the exterior of the inverter and batteries with a dry, soft cloth. Ensure ventilation openings are free from dust and debris.
- Connections: Annually inspect all electrical connections for tightness and signs of corrosion. Re-tighten if necessary.
- Environment: Ensure the installation environment remains within specified temperature and humidity ranges.
- Battery Health: Monitor battery voltage and performance via the LCD display or mobile app.
- Firmware: Check the manufacturer's website for any available firmware updates for the inverter and WiFi module.
