Diy Solar Charge Controller Arduino

The heart of the charge controller is an arduino nano board.

Diy solar charge controller arduino.

The arduino senses the solar panel and battery voltages by using two voltage divider circuits. Proper buck converter topology which increases the current on the output side not just pwm. Programmable with arduino ide. The arduino mcu senses the solar panel and battery voltages.

This is an atmega32u4 based synchronous mppt buck solar charge controller. In india most of the people are living in rural areas 400 million people that are currently have no access to electricity despite india being the world s 5th largest energy producer the existing electric grids are not capable of supplying the electricity need to those poor people. You can also use other arduino board like pro mini micro and uno. The amount of charging current is determined by the difference between battery voltage and charge setpoint voltages.

The output voltage of the voltage divides is one sixth 16 of the input voltage. Howtomakesolarchargecontroller solarpannel chargecontroller this video will show you how to build a home made solar charge controller featuring. It is very strong and durable but it always works silently. The input to tp4056 can be in the range of 4v to 8v which is the range of the output of the solar panel.

The voltage divider network r1 and r2 are used to scale down the voltage provided by the solar panel vpv so that the maximum voltage supplied to the arduino analog input a0 doesn t exceed it the maximum voltage limit which is 5v. The heart of the charge controller is arduino nano board. In the above picture there is typographical error in power and control signal. Simple mppt maximum power point tracking solar charge controller for 18v solar panels.

1 10 arduino based mppt solar charge controller download source code. This design is suitable for a 50w solar panel to charge a commonly used 12v lead acid battery. According to these voltages it decides how to charge the battery and control the load. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt.

According to these voltage levels it decides how to charge the battery and control the load. This voltage is given as input to the tp4056 li ion battery charging module which in this scenario acts as a solar charge controller. I can not kn. The microcontroller used is in this controller is arduino nano.
