Arduino Lithium Solar Charge Controller

5v or greater solar cell 3 7v lithium ion battery.

Arduino lithium solar charge controller.

This is an atmega32u4 based synchronous mppt buck solar charge controller. Please purchase this kit and panels from adafruit to ensure optimized functionality. 150v max current output. 12 72v max input voltage.

Adafruit industries unique fun diy electronics and kits usb dc solar lithium ion polymer charger v2 id. Built in dc gfp and arc fault solar wind energy and hydro mppt modes and extension of voc limit. Simple mppt maximum power point tracking solar charge controller for 18v solar panels. Programmable with arduino ide.

Midnite solar classic 150 charge controller type. I was also considering adding a small solar panel to the mix and using the solar panel to charge the battery. Trying out the ltc3780 dc dc buck boost module. Dc dc buck boost.

I m wondering if i can use the trinket itself as a smart charge controller to charge and monitor the battery. This configuration charges the battery as well as supply power to the circuit when the solar cell is producing energy. Very safe to use as it s equipped with an automatic arc fault detection that trips a circuit when it detects. Specification of version 2 charge controller.

The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable. Microcontroller based solar pv system s charge controller inverter powerbank led lamp with menu based navigation system on lcd display integrated solar chargecontroller inverter powerbank lamp project tutorial by shahariar. We cannot guarantee this will work with solar panels purchased elsewhere. This product is only designed for use with solar panels sold at the adafruit store.

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. 1 charge controller as well as energy meter 2. Electrical tape shrink tubing double sided foam tape solder altoids tin or other enclosure tools. At night the charge circuit disconnects and the battery is used as the power source for the circuit.

Soldering ion hot glue gun drill dremel. Proper buck converter topology which increases the current on the output side not just pwm. I combine both the energy meter and charge controller in this design.
