In this post I am showing you one very nice and simple solar powered egg incubator circuit project. Many people ask me bro how to upgrade simple incubator with solar charger and battery backup so egg will not spoil when main power line is going off. In rural areas power cut is major problem for […]
Solar Controller Circuits
90V to 400V Low Voltage Cutoff Circuit for Solar Inverters
Today we are going to discuss a purely analog high voltage protection circuit which is specially designed for solar power systems working with PV voltages from around 90 volts up to 400 volts DC. The main purpose of this circuit is to disconnect the inverter whenever the solar panel voltage falls below a safe level, […]
Smart Buck-Boost MPPT Solar Charger Circuit for 12V 24V Battery
In this post we are going to learn how we can make one real working smart solar battery charger circuit which can do MPPT charging. We are using Arduino Nano as the brain for controlling everything. We will also use INA219 sensor module so that we can read the solar voltage and current properly. And […]
True MPPT Solar Controller Circuit using IC 555
Are you wondering if it was possible to build a very simple MPPT circuit using ordinary parts like IC 555 and IC 741, which would work most efficiently imitating a true MPPT? The answer is yes, it is possible, and we will learn about it details, in the following article. In this design I used […]
Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch
So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]
PIR Controlled Solar Garden Light Circuit
In this post I have explained a simple automatic PIR controlled solar garden light circuit which will switch ON the LEDs only under two conditions: when it is completely dark and when a human being is detected in the vicinity. The above feature of the circuit ensures that the LEDs are turned ON only when […]
