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. More information below. Look up the ucn2906 lead acid charge controller ic. The pi consumes 5w or so and that is a lot of power to be wasting on a solar charge controller. 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. Another thing you can do when you get another pi is to try a usb ttl serial adapter. However the pi zero needs only 1 1 5a so make sure to adjust accordingly.
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. Most solar panels in the market today are 9v. They might not reply or they might say no but you should try. Buck regulator design isn t too difficult.
My victron solar charge controller and victron battery monitor are bluetooth only. 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. These boards are designed with a lot of flexibility for you to innovate your design. The more popular raspberry pi 4 s supply is recommended to be at 5v 2 2 5a current.
In this video i just quickly. A venus gx costs nearly 300 and a raspberry pi costs about 30. I was able to make the raspberry pi communicate with the charge controller using the pymodbus library and a cheap usb to rs485 adapter. Connecting the solar panel to the pi zero.
I used one of these usb to rs485 adapters. They re cheap and you can buy them anywhere. A few years ago lukas fässler needed a solar charge controller and made his own which he has been improving ever since. 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.
Custom system built for raspberry pi to visualize your solar installation and control it via mqtt. Or more accurately firmware that emulates their color control gx venus gx monitoring devices and it runs on a raspberry pi.
