Arduino Lithium Solar Charge Controller

I was also considering adding a small solar panel to the mix and using the solar panel to charge the battery.

Arduino lithium solar charge controller.

1 charge controller as well as energy meter 2. Electrical tape shrink tubing double sided foam tape solder altoids tin or other enclosure tools. Very safe to use as it s equipped with an automatic arc fault detection that trips a circuit when it detects. Midnite solar classic 150 charge controller type.

Programmable with arduino ide. 5v or greater solar cell 3 7v lithium ion battery. Built in dc gfp and arc fault solar wind energy and hydro mppt modes and extension of voc limit. I have a trinket that i m going to be powering off of a small lithium ion battery.

Trying out the ltc3780 dc dc buck boost module. Adafruit industries unique fun diy electronics and kits usb dc solar lithium ion polymer charger v2 id. I m wondering if i can use the trinket itself as a smart charge controller to charge and monitor the battery. Dc dc buck boost.

We cannot guarantee this will work with solar panels purchased elsewhere. Soldering ion hot glue gun drill dremel. This product is only designed for use with solar panels sold at the adafruit store. The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable.

Please purchase this kit and panels from adafruit to ensure optimized functionality. Arduino pwm solar charge controller v 2 02 to solve this problem i made this new version charge controller so that anyone can use it without changing the hardware and software. At night the charge circuit disconnects and the battery is used as the power source for the circuit. Proper buck converter topology which increases the current on the output side not just pwm.

12 72v max input voltage. I combine both the energy meter and charge controller in this design. 150v max current output. Specification of version 2 charge controller.

This configuration charges the battery as well as supply power to the circuit when the solar cell is producing energy. Simple mppt maximum power point tracking solar charge controller for 18v solar panels. This is an atmega32u4 based synchronous mppt buck solar charge controller.
