Raspberry Pi Solar Panel Monitor

The tiny versatile single board computer the raspberry pi or rbpi is suitable for gathering data from the pv panel and storing them in a database.

Raspberry pi solar panel monitor.

This is my solar battery monitoring system based on raspberry pi. Recommended solar panel i recommend a 12w solar panel for running any model raspberry pi. Fan control raspberry pi monitoring my pv solar panels with raspberry pi. Solar panel paramets and utility voltage parameters are accessible via web interface.

Communication with battery controller is made through raspberry pi serial port at 2400 baud. Simply monitor the voltage of the battery through an arduino and have it send a unique signal to the pi board as simple as true false high low 1 0 when the voltage dips below 3 7v so the raspberry pi can shut itself down. On the rbpi is a web server connected to the home ethernet network. I m setting up an off grid solar solution and the mppt controller i purchased only supports modbus via serial.

It monitors six solar panels connected to battery charging controller. Monitoring from afar kaspars configured his raspberry pi to connect to a nearby wifi access point via a standalone modem plugged in at his neighbour s house by setting the access credentials in the wpa supplicant conf file in the root of the sd card.

You can definitely get away with a 6w panel for the pi zero as well though this will largely depend on which peripherals you attach to it the zero. Another set of sensors monitor the battery voltage current and temperature. It is also capable of providing key information in terms of current voltage power and overall power efficiency.
