Solar Charge Controller Raspberry Pi

The charge controller is sold by multiple vendors such as ep solar sainsonic renogy etc.

Solar charge controller raspberry pi.

They might not reply or they might say no but you should try. I was able to make the raspberry pi communicate with the charge controller using the pymodbus library and a cheap usb to rs485 adapter. They re cheap and you can buy them anywhere. Most solar panels in the market today are 9v.

Or more accurately firmware that emulates their color control gx venus gx monitoring devices and it runs on a raspberry pi. A few years ago lukas fässler needed a solar charge controller and made his own which he has been improving ever since. This tutorial demonstrates how to use serial communication on a raspberry pi to connect to a solar charge controller and transmit the data using a python web. Custom system built for raspberry pi to visualize your solar installation and control it via mqtt.

I chose an old raspberry pi model a because it doesn t consume very much electricity and although it s under powered it can easily handle the 2 tasks of serial communication and web serving. Another thing you can do when you get another pi is to try a usb ttl serial adapter. Buck regulator design isn t too difficult. Better to use µw with a small microcontroller.

This is the ultimate solar panel controller for raspberry pi and arduino projects. New solar panels on top of the project curacao box weatherrack in background. A venus gx costs nearly 300 and a raspberry pi costs about 30. The design is now mature and the high efficiency mppt solar charger is.

I still think you should email the manufacturer of the solar charge controller to be sure you have the correct pinout of the 8 pin rj45 socket and the specification for the output voltage. The pi consumes 5w or so and that is a lot of power to be wasting on a solar charge controller. However the pi zero needs only 1 1 5a so make sure to adjust accordingly. Look up the ucn2906 lead acid charge controller ic.

My victron solar charge controller and victron battery monitor are bluetooth only. Connecting the solar panel to the pi zero. More information below. The epsolar tracer2210a charge controller including their bn range has an rj45 port which can be used to connect an optional monitor or to windows monitoring software.

I think that a microcontroller is as is so often the case here a much better idea than using a pi. In this video i just quickly.
