How to monitor a domestic photovoltaic plant with Arduino
ArdaSol is the name of a project for a solar energy monitoring system based on Arduino Mega and UNO, made by Heinz Pieren. It’s a system built to monitor energy production and consumption of a domestic photovoltaic plant:
The ArdaSol Energy Monitoring System has 3 devices:
- ArdaSol Display based on a Arduino Mega Board
The master of the system, it collects the data from the two other ArdaSol devices, shows the data on the display, stores it on a SD card and sends it to a server in the internet.- ArdaSol Energy Monitor based on a Arduino Uno
Measures the consumption of the energy, shows energy values on local display and delivers it on request to the ArdaSol Display.- ArdaSol Remote PVI Interface based on a Arduino Uno
The photovoltaic inverter (PVI) has a RS485 interface, this is connected to ArdaSol Remote, which interacts as a gateway to ArdaSol Display. It converts the requests, coming with a radio signal to the PVI and vice versa.
