Practical advice is shared regarding cable management, such as using cable ties to secure breakers and drilling precise holes for waterproof connectors. This guide covers specific connections for solar panel inputs, battery terminals, and grid integration to ensure a functional home power system. By demonstrating the assembly process outside of the final wall mount, this tutorial offers a clear visual roadmap for DIY enthusiasts. This first installment of the series focuses on the internal box configuration in preparation for the final installation of solar panels.

Here is a detailed guide on the phase one wiring and safety device setup for a Deye 6kW Hybrid Inverter.

Overview of the Wiring Strategy.

This phase focuses on the "pre-wiring" of the distribution box and safety devices before they are mounted and connected to the inverter. The setup involves three primary sections: Solar (DC) Input, AC Grid/Load, and the Manual Transfer Switch (MTS) for bypass functionality.

1. Solar (DC) Input Wiring.

The DC side manages the power coming from the solar panels.

• Panel Configuration: The setup uses eight solar panels connected in series, which will be detailed further in part two of the guide.
• Protection: Positive and negative wires from the roof enter a DC Breaker.
• Surge Protection: A DC Surge Protection Device (SPD) is connected in parallel with the input wires to protect the system from voltage spikes.
• Inverter Connection: The output from the DC breaker goes directly to the inverter's PV1 terminals. In this specific setup, only one string (PV1) is utilized.

2. AC Grid and Load Connections.

This section handles the interface between the inverter, the utility grid, and the home's electrical load.

• Load Wiring: The inverter’s Load output connects to a dedicated Load Breaker. The output of this breaker then feeds into the MTS (Terminals 4 and 8).
• Grid Wiring: The utility grid connects to an AC/Grid Breaker.
• AC Surge Protection: Similar to the DC side, an AC SPD is wired in parallel with the grid input to safeguard against external overcurrent or grid anomalies.
• Inverter Grid Input: The output of the grid breaker connects to the inverter's Grid input.

The MTS is critical for maintaining power if the inverter needs servicing.

• Inverter Mode: When the MTS is up, it draws power from the inverter’s load output (Terminals 4 and 8).
• Bypass Mode: A parallel connection is made from the grid input to the MTS (Terminals 2 and 6). This allows you to bypass the inverter and run the house directly from the grid if the inverter is offline.
• House Load: Terminals 1 and 5 of the MTS are the final output leads that connect to the main breaker box of the home.

4. Battery Setup.

• Direct Connection: The battery connects to the inverter’s battery terminals and its communication port for the BMS (Battery Management System).
• Breaker Requirement: If the battery has a built-in breaker, a separate MCCB (Molded Case Circuit Breaker) is redundant and unnecessary.

5. Practical Installation & Safety Tips.

• Enclosure Choice: A plastic distribution box is often preferred for DIY setups as it is easier to drill than metal, though metal is considered the "professional" standard.
• Cable Glands (PG11): Use these at every entry/exit point of the breaker box to make the setup waterproof and prevent pests like lizards from entering the enclosure.
• The "Cable Tie" Technique: Because breakers can sometimes spread apart or "open" when multiple parallel wires are inserted, using a cable tie as a stopper can keep the components tightly aligned.

Wiring Precision:

1. Strip wires to approximately 10mm to 12mm to ensure they fit snugly into terminals without exposing bare copper.
2. Perform a "pull test" after tightening every wire to ensure the connection is secure.

MC4 Connectors: Note that the MC4 connectors included with the Deye inverter may be a "solid" type requiring a specific crimping tool; ensure you have the correct tool or compatible connectors before beginning.

6. Grounding Requirements.

Proper grounding is essential for the safety devices to function.

• SPD Grounding: Both the AC and DC SPDs must be linked to a common grounding cable.
• Inverter Grounding: A dedicated grounding wire should run from the inverter's chassis (usually located at the bottom) to the main grounding bus.
