4. Setup

4.1 Physical Installation

The inverter should be mounted securely in a location that is dry, well-ventilated, and protected from direct sunlight and extreme temperatures. Due to its weight (54 lbs), ensure the mounting surface can support the load. Consider accessibility for future adjustments and maintenance.

4.2 Electrical Connections

All electrical wiring must comply with local and national electrical codes. Use appropriate wire gauges for all connections to ensure safety and optimal performance.

4.2.1 Battery Connections

Connect the battery cables to the inverter's battery terminals. Ensure correct polarity: positive (+) to positive and negative (-) to negative. Tighten all connections securely to prevent loose contacts and potential hazards.

4.2.2 PV Input Connections

Connect your solar PV array to the designated PV input terminals on the inverter. Observe correct polarity and ensure the open circuit voltage of the PV array does not exceed 500VDC.

4.2.3 AC Input/Output Connections

Connect the AC input from your utility grid or generator, and the AC output to your loads. The inverter supports both 120V/240V split-phase and 120V single-phase configurations. Refer to the wiring diagram for specific connections.

4.3 Initial Power-Up and Configuration

After all physical and electrical connections are made, proceed with the initial power-up. The inverter's LCD display allows for configuration of various settings, including battery type, charging modes, and output priorities.

5. Operating Modes

The SPH10K48SP-P inverter offers versatile operating modes to optimize energy usage based on your specific needs:

5.1 Charging Modes:

• Hybrid Charging: Utilizes both solar and utility power for battery charging.
• Utility Priority Charging: Prioritizes utility power for charging, with solar as a supplement.
• Solar Priority Charging: Prioritizes solar power for charging, with utility as a backup.
• Only Solar Charging: Charges batteries exclusively from solar power.

5.2 Output Modes:

• Utility Priority: Loads are primarily powered by the utility grid.
• Solar and Utility Hybrid: Dynamically uses solar and utility to power loads.
• Solar Priority: Loads are primarily powered by solar, then batteries, then utility.
• Inverter Priority: Loads are primarily powered by the inverter (from batteries/solar), then utility.

6. Time-Slot Charging/Discharging Function

The inverter features a time-slot function, allowing users to configure specific charging and discharging periods. This is particularly useful for optimizing energy usage based on local peak and off-peak electricity tariffs, maximizing savings and efficient use of PV energy.

• Time-slot Utility Charging/Carrying: Set up to three definable periods for utility charging. If PV energy is unavailable or insufficient, utility energy will be used as a supplement.
• Time-slot Battery Discharging: Set up to three definable periods for battery discharging. During these periods, the inverter prioritizes battery power for loads, switching to mains power if battery power is insufficient.

7. Battery Compatibility

The SPH10K48SP-P inverter is compatible with a wide range of 48V battery types, including:

• AGM/Sealed
• Gel
• Flooded
• Lithium (LiFePO4)
• User-defined (for custom battery parameters)

It also supports battery-free operation. For lithium batteries, the mains power and photovoltaics can activate a dormant battery. The inverter supports CAN, USB, and RS485 communication with SUNGOLDPOWER batteries for enhanced management.

8. Parallel Function

For increased power output or to create a three-phase system, the SPH10K48SP-P inverter supports parallel connection of up to 6 units. This allows for scalable power solutions to meet diverse energy demands.

9. Communication & Monitoring

The integrated WiFi module allows users to monitor the inverter's operating status and parameters remotely via a mobile application. BMS communication (CAN, USB, RS485) ensures seamless integration and optimized performance with compatible battery systems.

10. Maintenance

Regular maintenance ensures the longevity and optimal performance of your inverter. Perform the following checks periodically:

• Visual Inspection: Check for any visible damage, loose connections, or signs of overheating.
• Cleaning: Keep the inverter's ventilation openings clear of dust and debris to ensure proper airflow. Use a dry cloth for cleaning.
• Connection Checks: Periodically verify that all electrical connections (battery, PV, AC) are tight and secure.
• Environment: Ensure the installation environment remains within the specified temperature and humidity ranges.

11. Troubleshooting

If the inverter displays an error code or exhibits unusual behavior, consult the user manual for specific troubleshooting steps. Common issues and general solutions include:

• No Power: Check all circuit breakers, battery connections, and input power sources.
• Low Output Power: Verify PV array performance, battery state of charge, and load requirements.
• Overload Warning: Reduce connected loads. Ensure total load does not exceed the inverter's rated capacity.
• Communication Error: Check communication cables and settings for BMS or WiFi modules.
