4. Setup and Installation

4.1 Unpacking and Inspection

Upon receiving the inverter, carefully unpack it and inspect for any shipping damage. Report any damage to your supplier immediately. Ensure all components listed in the packing list are present.

4.2 Mounting the Inverter

Choose a suitable location for mounting the inverter. It should be:

• Indoors, protected from direct sunlight, rain, and moisture.
• Well-ventilated to allow for heat dissipation. Maintain at least 20 cm (8 inches) clearance from other objects.
• Mounted vertically on a solid surface capable of supporting its weight.
• Away from flammable materials and corrosive gases.

4.3 Wiring Connections

All wiring must comply with local and national electrical codes. Use appropriate wire gauges for all connections. Refer to the connection diagram below for proper wiring sequence.

Figure 4.1: Detailed connection diagram for the inverter.

1. Battery Connection: Connect the 24V battery bank to the BAT+ and BAT- terminals. Ensure correct polarity. The inverter is compatible with 24V Lithium, Lead-Acid (Sealed, AGM, Gel, Flooded) batteries.
2. Solar Panel Connection: Connect your solar panels to the PV+ and PV- terminals. Observe the maximum PV open circuit voltage of 100Vdc and MPPT voltage range of 30-85Vdc. Max PV input power is 1600W.
3. AC Input Connection: Connect the mains power or a generator to the AC IN terminals. Input voltage range is 90-140Vac. Max AC charging current is 0-63A.
4. AC Output Connection: Connect your home loads to the AC OUT terminals. The inverter provides 3000W of AC output power.
5. WiFi Module Installation: Insert the provided WiFi module into the designated port for remote monitoring capabilities.

4.4 Battery Compatibility

5. Operating Instructions

5.1 Powering On/Off

1. Power On: Ensure all connections are secure. Turn on the battery breaker first, then the solar panel breaker (if applicable), and finally the AC input breaker (if applicable). Switch the inverter's power button to 'ON'.
2. Power Off: Reverse the power-on sequence. First, switch the inverter's power button to 'OFF'. Then, disconnect the AC input, followed by the solar panels, and finally the battery bank.

5.2 LCD Display and LED Indicators

The LCD screen provides real-time operational data and allows for parameter adjustments. Three LED indicators (Charge, Fault, AC) provide quick status updates.

• Charge LED: Indicates battery charging status.
• Fault LED: Illuminates in case of system errors or malfunctions.
• AC LED: Indicates AC input/output status.

5.3 Charging Modes

The inverter offers four selectable charging modes:

• Solar Only: Prioritizes solar power for charging.
• Mains Priority: Prioritizes utility grid power for charging.
• Solar Priority: Uses solar power first, then supplements with mains power if solar is insufficient.
• Mains & Solar Hybrid Charging: Combines both mains and solar power for charging.

5.4 Output Modes

The inverter supports two output modes:

• Mains Bypass: AC loads are powered directly by the utility grid.
• Inverter Output: AC loads are powered by the inverter, drawing energy from batteries or solar.

Figure 5.1: Overview of charging and discharging modes.

5.5 ECO Mode

The ECO mode is a power-saving feature designed to reduce no-load consumption. When enabled, if the load connected to the inverter is less than 50W, the inverter output will be delayed for 3 minutes and then automatically switch off. To resume output, press the enclosure switch to "OFF" and then back to "ON".

5.6 WiFi Monitoring

The integrated WiFi port allows for remote monitoring of the inverter's performance via a smartphone application. Please refer to the separate WiFi module instructions for app download and setup. Note: Some users have reported challenges with app availability or functionality in certain regions.
