A Flask-based application for monitoring Deye Inverters (and compatible models) using the Solarman V5 protocol. This tool connects directly to the inverter via Modbus over TCP to read real-time data including voltages, currents, battery status, and BMS information.

Features

Real-time Monitoring: Reads critical data such as Input/Output Voltage, Grid/Load Currents, Battery SOC, Temperature, and Power.
BMS Integration: Retrieves detailed Battery Management System (BMS) data for up to two battery packs.
Web Interface: Provides a user-friendly dashboard to view inverter status (served at /).
JSON API: Exposes raw data via a RESTful endpoint (/api/data) for integration with other systems.
PDF Utility: Includes a tool to extract register information from Deye Modbus PDF manuals.

Prerequisites

Python 3.x
A Deye Inverter (or compatible) connected to the network.
Inverter IP address, Serial Number, and Modbus Slave ID.

Installation

Clone the repository:

git clone <repository-url>
cd deyeChargeSpeed

Create and activate a virtual environment:

python -m venv venv
# Windows
.\venv\Scripts\activate
# Linux/Mac
source venv/bin/activate

Install dependencies:
```
pip install -r requirements.txt
```

Configuration:

Copy the example configuration file and update it with your inverter details:

cp config.py.example config.py

Edit config.py:

INVERTER_IP = "192.168.x.x"
INVERTER_SERIAL = 1234567890
INVERTER_PORT = 8899
INVERTER_SLAVE_ID = 1

Usage

Start the application:
```
python app.py
```
Access the dashboard:

Open your web browser and navigate to http://localhost:5000.

Utilities

PDF Register Extractor

Located in docs/extract_pdf.py, this script helps identify Modbus registers from Deye PDF manuals.

Usage:

Place your PDF manual in the docs/ folder.
Update the filename in docs/extract_pdf.py if necessary (defaults to Modbus储能-组串-微逆宁波德业V118-1.pdf).
Run the script:
```
python docs/extract_pdf.py
```
Check pdf_output.txt for the extracted register locations and context.
