Diy solar panel charge controller

What is a DIY solar charge controller?

A DIY solar charge controller is a device that you can build yourself to regulate the voltage and current coming from your solar panels. It is used to maintain the proper charging voltage on the batteries, preventing overcharging and thus protecting your solar battery storage system.

How do you charge a solar panel?

Locate the solar terminals on your charge controller. Connect the solar panel’s cables to the solar terminals. Place the solar panel outside in direct sunlight and confirm that the battery begins charging. Your charge controller should indicate in some way that the panel is charging the battery. Locate the load terminals on your charge controller.

How does a solar charge controller work?

It’s a 555 based simple circuits the charge the battery when the battery charge goes below the lower limits, and stop charging when the battery reaches it's upper limit voltage “To make a cheap and efficient solar charge controller” This is the driving circuit of the DIY AUTOMATIC SOLAR CHARGE CONTROLLER. To make this circuit you need 1.

What is the best solar charge controller?

You can also use other Arduino board like Pro Mini,Micro and UNO. Nowadays the most advance solar charge controller available in the market is Maximum Power Point Tracking (MPPT). The MPPT controller is more sophisticated and more expensive. It has several advantages over the earlier charge controller.

Why do solar panels need a charge controller?

So the Solar panel is now behaving like a 66-watt panel. This equates to a loss of 100W-66.6W = 34W ( 33.4%). This is the reason for using an MPPT charge controller instead of a standard charge controller like PWM. The MPPT controller is consists of a DC-DC converter where the duty cycle is varied to track the Maximum Power Point.

Which microcontroller is used in a solar charge controller?

The microcontroller used is in this controller is Arduino Nano. This design is suitable for a 50W solar panel to charge a commonly used 12V lead-acid battery. You can also use other Arduino board like Pro Mini,Micro and UNO. Nowadays the most advance solar charge controller available in the market is Maximum Power Point Tracking (MPPT).
