3. Setup and Installation

3.1 Unpacking and Inspection

Upon receiving the inverter, carefully unpack and inspect it for any damage. The package should include:

• 10000W solar inverter
• Parallel communication cable
• 2 x Battery Terminal Lugs
• 2 x M5 screws
• Instruction manual

3.2 Mounting the Inverter

Mount the inverter vertically on a sturdy wall in a clean, dry, and well-ventilated area. Ensure adequate clearance around the unit for proper heat dissipation.

3.3 Wiring Connections

All wiring must comply with local and national electrical codes. Use appropriate wire gauges for all connections.

3.3.1 Battery Connection

Connect the 48V battery bank to the inverter's battery terminals. Ensure correct polarity. The inverter supports AGM, Gel, Lead-acid, Lithium-ion, and LiFePO4 batteries, and can operate without batteries.

3.3.2 PV Input Connection

Connect the solar panels to the PV input terminals. The inverter features dual MPPT trackers, supporting two independent solar inputs. Max PV input power is 11KW (5500W per input), with a maximum PV input voltage of 500Vdc and starting voltage > 150V. PV wire gauge: 10AWG.

4. Operation

4.1 Powering On/Off

1. Power On: Ensure all connections are secure. Switch on the AC input breaker, then the DC battery breaker (if applicable), and finally the inverter's ON/OFF rocker switch.
2. Power Off: Reverse the power-on sequence. First, switch off the inverter's ON/OFF rocker switch, then the DC battery breaker, and finally the AC input breaker.

4.2 LCD Display and Settings

The LCD screen provides real-time monitoring of photovoltaic system operating data. Use the touchable keys to navigate menus and adjust settings.

4.3 Charging Modes

The inverter offers four charging modes:

• Solar Only: Charges batteries exclusively from solar power.
• Mains Priority: Charges batteries primarily from the utility grid, with solar as a supplement.
• Solar Priority: Charges batteries primarily from solar, with the utility grid as a supplement.
• Mixed Mains/PV Charging: Utilizes both utility and PV power for charging.

4.4 Output Modes

The inverter supports two output modes:

• Utility Bypass: Loads are powered directly by the utility grid.
• Inverter Output: Loads are powered by the inverter (from solar or battery).

4.5 Time-Slot Charging/Discharging

The inverter features a time-slot charging and discharging function, allowing users to set specific periods for charging and discharging based on local electricity tariffs. This optimizes energy usage and can reduce costs.

Note: Before using this function, set the local time in parameters 54 and 55, then configure the time slots.

4.6 Power Saving Mode

Enable power saving mode to conserve energy. If the load power drops below 50W, the inverter will switch off after a 5-minute delay. When the load exceeds 50W, the inverter automatically restarts.

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter.

• Cleaning: Periodically clean the exterior of the inverter with a dry cloth. Ensure ventilation openings are free from dust and debris. The inverter features a detachable insect-proof screen for easy cleaning.
• Connections: Annually inspect all electrical connections for tightness and signs of corrosion.
• Environment: Ensure the installation environment remains within specified temperature and humidity ranges.
• Firmware Updates: Check the manufacturer's website for any available firmware updates.
