MPPT ROS Package
ROS package for Victron Energy MPPT devices via VE-Direct Protocol from serial USB
Introduction
This repository is part of my end-of-degree project as mechanical engineer at University of Almería in Spain. The aim of this project is to install a PV system into an electric vehicle, creating a data sender from the MPPT device into the ros-system.
MPPT Connection
This software is tested with a VE.Direct to USB Interface cable
How it works
At the moment, it sends the most important data from the ve-direct protocol, which are defined in mppt.msg:
- Battery Voltage (v_bat) - float64
- Battery Current (i_bat) - float64
- Solar Panels Voltage (v_pv) - float64
- Solar Panel Power (p_pv) - float64
Run roscore and vemppt_ros.py
Customize the sender packets
Depending on the interested values from the serial communication interface, it is possible to define more values into the package.
MPPT valid values:
| Implemented | Label | Units | Description |
|---|---|---|---|
| ✓ | V | mV | Main (battery) voltage |
| ✓ | I | mA | Battery current |
| ✓ | VPV | mV | Panel voltage |
| ✓ | PPV | W | Panel power |
| - | PID | - | Product ID |
| - | SER# | - | Serial Number |
| - | HSDS | - | Day sequence number (0...364) |
| - | MPPT | - | Tracker operation mode |
| - | ERR | - | Error code |
| - | CS | - | State of operation |
| - | H19 | 0.01 kW/h | Yield Total (user resettable counter) |
| - | H20 | 0.01 kW/h | Yield today |
| - | H21 | W | Maximum power today |
| - | H22 | 0.01 kW/h | Yield yesterday |
| - | H23 | W | Maximum power yesterday |
