Arduino Lithium Solar Charge Controller

I have a trinket that i m going to be powering off of a small lithium ion battery.

Arduino lithium solar charge controller.

Proper buck converter topology which increases the current on the output side not just pwm. The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable. Specification of version 2 charge controller. I m wondering if i can use the trinket itself as a smart charge controller to charge and monitor the battery.

Programmable with arduino ide. This configuration charges the battery as well as supply power to the circuit when the solar cell is producing energy. This is an updated version of a charge controller circuit i ve had up for a while. Electrical tape shrink tubing double sided foam tape solder altoids tin or other enclosure tools.

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. 12 72v max input voltage. I was also considering adding a small solar panel to the mix and using the solar panel to charge the battery.

1 charge controller as well as energy meter 2. 150v max current output. 5v or greater solar cell 3 7v lithium ion battery. Midnite solar classic 150 charge controller type.

Simple mppt maximum power point tracking solar charge controller for 18v solar panels. This is an atmega32u4 based synchronous mppt buck solar charge controller. 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. Soldering ion hot glue gun drill dremel.

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. This product is only designed for use with solar panels sold at the adafruit store. Dc dc buck boost. I combine both the energy meter and charge controller in this design.

We cannot guarantee this will work with solar panels purchased elsewhere. 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. Very safe to use as it s equipped with an automatic arc fault detection that trips a circuit when it detects.
