4.3 Wiring Diagram

Refer to the following diagram for a typical inverter application system setup.

This diagram illustrates how the 11.4KW Hybrid Inverter integrates into an energy system. It shows connections from a PV Array to the inverter, and from the inverter to a Battery bank, Grid (via a Sensor), and various loads (Normal Load, Smart Load). The system also supports a Generator or On-Grid Inverter, and includes a Monitoring Device connected to the Cloud for remote access.

Wiring Steps:

1. Connect the battery cables to the inverter's battery terminals, ensuring correct polarity.
2. Connect the PV array cables to the inverter's PV input terminals, observing polarity and voltage limits.
3. Connect the AC input from the grid to the inverter's grid input terminals.
4. Connect the AC output to your loads.
5. Ensure all connections are secure and properly insulated.
6. Connect communication cables (WiFi module, BMS, parallel cable) as required.

5. Operating Modes

The inverter supports various operating modes to optimize energy usage based on your preferences and grid conditions.

This diagram illustrates the four primary AC output work modes: Self-consumption, Feed-in Priority, Back-up, and Off Grid Mode. Each mode shows the flow of energy between the load, battery, and grid, indicating how the inverter prioritizes power sources under different conditions.

• Self-consumption Mode: Prioritizes using solar power and battery energy for local loads before drawing from the grid.
• Feed-in Priority Mode: Prioritizes feeding excess solar power back into the grid.
• Back-up Mode: Ensures continuous power to critical loads using battery backup when the grid fails.
• Off Grid Mode: Operates independently from the utility grid, relying on solar and battery power.

5.1 Forced Charge/Discharge Function

The inverter allows users to set specific time periods for forced battery charging or discharging, regardless of the current operating mode (Self-consumption, Feed-in Priority, or Back-up Mode).
