Arduino Lithium Solar Charge Controller

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.

Arduino lithium solar charge controller.

Adafruit industries unique fun diy electronics and kits usb dc solar lithium ion polymer charger v2 id. Programmable with arduino ide. 150v max current output. Simple mppt maximum power point tracking solar charge controller for 18v solar panels.

Trying out the ltc3780 dc dc buck boost module. At night the charge circuit disconnects and the battery is used as the power source for the circuit. I m wondering if i can use the trinket itself as a smart charge controller to charge and monitor the battery. 5v or greater solar cell 3 7v lithium ion battery.

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. I was also considering adding a small solar panel to the mix and using the solar panel to charge the battery. Please purchase this kit and panels from adafruit to ensure optimized functionality. Proper buck converter topology which increases the current on the output side not just pwm.

Midnite solar classic 150 charge controller type. 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. The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable.

Specification of version 2 charge controller. 12 72v max input voltage. I combine both the energy meter and charge controller in this design. This is an updated version of a charge controller circuit i ve had up for a while.

Dc dc buck boost. 1 charge controller as well as energy meter 2. 2 600mah 4 400mah 6 600mah lithium battery charge controller dc dc usb boosting circuit 2 5mm female panel mount plug 2 5mm male jack with wire 1n4001 diode wire building supplies. This product is only designed for use with solar panels sold at the adafruit store.

We cannot guarantee this will work with solar panels purchased elsewhere. Built in dc gfp and arc fault solar wind energy and hydro mppt modes and extension of voc limit. This is an atmega32u4 based synchronous mppt buck solar charge controller.
