## Article

### Project Overview

**Project-OVSG** is a prototype system designed to monitor the status of a solar power station.
It is based on the **WIZnet W5500-EVB-Pico** board and utilizes two **INA260** sensors to measure real-time voltage, current, and power data for both the solar panel and system load.
Currently, the data is output via Serial, with a structure suitable for future expansion to Ethernet-based communication.

### Hardware Configuration

| Component | Description |
| --- | --- |
| WIZnet W5500-EVB-Pico | RP2040 MCU with built-in W5500 Ethernet controller |
| INA260 (x2) | I2C-based voltage, current, and power sensor |
| GPIO 21, 22 | Used as I2C SDA and SCL |
| Power Input | Simulated solar input and load wiring for test purposes |

---

### System Operation

1. Initializes I2C and configures two INA260 sensors

2. Periodically reads voltage (V), current (A), and power (W) values

3. Prints measured values over Serial

4. Designed to support future Ethernet-based data transmission

---

### Technical Benefits

- Power metrics can be acquired without analog circuitry using INA260

- Stable serial-based debugging structure

- Existing ESP32 version implemented for alternative hardware support

**Why W5500-EVB-Pico is a suitable choice**:

- Combines RP2040 MCU and W5500 Ethernet controller on a single compact board

- RP2040 provides dual-core performance and ample GPIOs for I2C + Ethernet multitasking

- Wide software support in CircuitPython, C SDK, and Arduino environments

- Built-in hardware TOE enables reliable socket-based Ethernet communication in future extensions

---

### Conclusion

Project-OVSG demonstrates a lightweight and modular approach to **monitoring solar power system metrics**,
with a clear path toward **integration into IIoT applications**.
By using the W5500-EVB-Pico board, both sensor control and network capability are unified on a single platform.
The open-source structure and low-power design make it easy to adopt for industrial, educational, or field-deployed scenarios.
