4. Setup and Installation

4.1 System Connection

The inverter supports both split-phase (120V/240V) and single-phase (120V) output configurations. PV panels can charge the battery and supply power to the load. If PV or battery power is insufficient, the system can draw power from the grid or a generator.

Figure 4: Typical System Connection

This diagram illustrates how the SUNGOLDPOWER inverter connects to PV panels, an external battery pack, the utility grid, a generator, and various home appliances for both split-phase and single-phase modes.

4.2 Parallel Function

The inverter supports parallel connection of up to 6 units for increased power capacity. This can be configured for split-phase or three-phase systems.

Figure 5: Parallel Connection Wiring Diagrams

This image displays wiring diagrams for connecting multiple SUNGOLDPOWER inverters in parallel, including configurations for two parallel-connected split-phase inverters, a three-phase system with three inverters (1+1+1), and a three-phase system with six inverters (2+2+2).

5. Operating Modes

The SUNGOLDPOWER inverter offers flexible operating modes to optimize energy usage based on your requirements.

5.1 Charging and Output Modes

There are four distinct AC output modes and four battery charging modes available:

This diagram illustrates the four AC output modes (Utility Priority, Solar and Utility Hybrid, Solar Priority, Inverter Priority) and four battery charging modes (Hybrid Charging, Utility Priority, Solar Priority, Only Solar) to meet various energy management needs.

• AC Output Modes: Utility Priority, Solar and Utility Hybrid, Solar Priority, Inverter Priority.
• Battery Charging Modes: Hybrid Charging, Utility Priority Charging, Solar Priority Charging, Only Solar Charging.

5.2 Time-Slot Charging/Discharging Function

The SPH series is equipped with a time-slot function, allowing users to set specific charging and discharging periods. This feature enables rational use of utility power and PV energy, especially beneficial for optimizing against local peak and valley tariffs.

Figure 7: Time-Slot Charging/Discharging

This image explains the time-slot utility charging/carrying function and the time-slot battery discharging function, demonstrating how users can define periods for charging from the grid during trough times and discharging during set periods to avoid voltage peaks, in conjunction with peak-valley electricity tariffs.

6. Battery Compatibility

The SUNGOLDPOWER 8000W DC 48V solar inverter is compatible with a wide range of 48V battery types, including AGM/Sealed, Gel, Flooded, and Lithium batteries. A User Mode is also available for custom battery settings. The inverter supports battery-free operation and can activate dormant lithium batteries using mains power or photovoltaics.
