4.2 Step-by-Step Installation

1. Mount the Inverter: Use the provided fixing screws to securely attach the inverter to the photovoltaic panel bracket. Ensure the mounting location allows for adequate ventilation and is protected from direct sunlight if possible, despite its waterproof rating.
2. Connect DC Input: Connect the positive and negative poles of the DC connection plug from the photovoltaic panel(s) to the corresponding DC input terminals on the inverter. Ensure correct polarity. The DC input is designed with MC4 connectors to prevent reverse polarity.
3. Connect AC Output: Open the waterproof cover of the AC output connector on the inverter. Connect the AC cable to the waterproof AC socket. Ensure a secure and watertight connection.
4. Connect to Main AC Line: Connect the AC output line from the inverter to the main AC line of your electrical system. This connection should be performed by a qualified electrician.
5. Repeat for Multiple Inverters (if applicable): If installing multiple inverters, repeat steps 1-3 for each unit. Multiple inverters can be stacked arbitrarily to form a single-phase parallel stacking system.
6. Connect to Grid: Connect the main AC cable from your inverter system to the utility grid. This final connection initiates your green energy generation.

4.3 Multiple Inverter Installation and Wiring

Multiple inverters can be connected in a stacked configuration. There is no model limit, allowing for mixing and matching as needed. Each inverter operates independently without interference.

Figure 4.2: Illustration of multiple micro inverters installed in a stacked arrangement, along with a diagram detailing the grid-connected cable components and terminal wire hole schematic (L-brown, N-blue, G-yellow & green).

The current of each group connected in series to the AC box can reach 50 Amps.

Figure 4.3: Wiring diagrams for both single-phase and three-phase connections of multiple micro inverters to the power grid. Includes notes on WiFi signal strength and cable requirements for longer distances.

For single-phase connections, up to 6 inverters can be connected at 110V, and up to 12 inverters at 230V. For three-phase connections, similar limits apply per phase. Ensure proper cable sizing; for distances over 10m from the network point, use 3*4mm² cable, and for distances over 20m, use 3*6mm² cable.

5. Operation and Monitoring

The WVC-1600W inverter features WiFi connectivity and a mobile application for smart monitoring of your solar power system. This allows for real-time data analysis and control.
