5. Setup and Installation

5.1 Site Selection:

• Install the inverter indoors, in a dry, well-ventilated area.
• Avoid direct sunlight, high temperatures, and high humidity.
• Ensure sufficient clearance (at least 20 cm) around the inverter for proper airflow.
• Mount on a non-flammable surface.

5.2 Mounting the Inverter:

1. Select a suitable vertical wall surface.
2. Mark the positions for the mounting screws using the inverter as a template.
3. Drill pilot holes and insert appropriate wall anchors if necessary.
4. Securely mount the inverter to the wall using the provided mounting screws.

5.3 Wiring Connections:

WARNING: Ensure all power sources are disconnected before making any wiring connections. Incorrect wiring can cause severe damage to the inverter, batteries, and connected loads, and poses a risk of electric shock.

1. Battery Connection:
   • Connect the positive (+) terminal of the 24V battery bank to the positive (+) DC input terminal on the inverter.
   • Connect the negative (-) terminal of the 24V battery bank to the negative (-) DC input terminal on the inverter.
   • Ensure correct polarity. Reverse polarity will damage the inverter.
   • Use appropriate gauge cables for the battery connection, considering the inverter's current rating.
2. Solar Panel Connection (PV Input):
   • Connect the positive (+) output from your solar panel array to the PV+ terminal on the inverter.
   • Connect the negative (-) output from your solar panel array to the PV- terminal on the inverter.
   • Verify that the open-circuit voltage (Voc) of your solar array does not exceed the maximum PV input voltage specified for the GD3024EMH.
   • Ensure correct polarity.
3. AC Output Connection:
   • Connect your AC loads (appliances, lights, etc.) to the AC output terminals of the inverter.
   • Ensure the total power consumption of your loads does not exceed the inverter's rated output power (3000W).
   • Properly ground the inverter according to local electrical codes.

5.4 Initial Power-Up:

1. Double-check all wiring connections for tightness and correct polarity.
2. Connect the battery bank to the inverter.
3. If solar panels are connected, ensure they are receiving sunlight.
4. Turn on the inverter's power switch.
5. Observe the LCD display for status indicators and any error messages.

6. Operating the Inverter

6.1 LCD Display and Control Buttons:

The LCD display provides real-time information about the inverter's status, input/output voltages, battery charge level, and error codes. Use the control buttons (typically UP, DOWN, ENTER/SET, ESC) to navigate through menus and adjust settings.

6.2 Basic Operation:

• Power On/Off: Press and hold the power button for a few seconds to turn the inverter on or off.
• Monitoring: Cycle through the display screens to view various parameters such as PV input voltage, battery voltage, AC output voltage, load percentage, and operating mode.
• Setting Parameters: Access the settings menu to configure battery type, charging current, AC output voltage/frequency, and other operational parameters. Refer to the detailed menu structure in the full manual for specific adjustments.

6.3 Operating Modes:

The GD3024EMH typically supports various operating modes, such as:

• Solar Priority: Solar power is used first to power loads and charge batteries.
• Utility Priority (if applicable): AC utility power is used first, with solar as a backup. (Note: This is an off-grid inverter, so utility priority might refer to a generator input if available, or not be present).
• Battery Priority: Loads are powered primarily from batteries, with solar charging them.

Select the appropriate mode based on your energy usage and solar availability.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your UPGENT inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
• Connections: Annually check all wiring connections (battery, solar, AC output) for tightness and corrosion. Loose connections can cause overheating and poor performance.
• Battery Inspection: Regularly inspect your battery bank for signs of damage, corrosion, or swelling. Ensure battery terminals are clean and tight. Follow the battery manufacturer's maintenance guidelines.
• Environment: Ensure the installation environment remains within the specified temperature and humidity ranges.
• Firmware Updates: Check the UPGENT website or contact support for any available firmware updates, if applicable.
