Arduino Lithium Solar Charge Controller

I combine both the energy meter and charge controller in this design.

Arduino lithium solar charge controller.

12 72v max input voltage. Programmable with arduino ide. Adafruit industries unique fun diy electronics and kits usb dc solar lithium ion polymer charger v2 id. This product is only designed for use with solar panels sold at the adafruit store.

I have a trinket that i m going to be powering off of a small lithium ion battery. 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 is an updated version of a charge controller circuit i ve had up for a while. The 03962a charge controller also allows charging from a 5 v cell phone charger usb mini cable.

Simple mppt maximum power point tracking solar charge controller for 18v solar panels. Midnite solar classic 150 charge controller type. 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.

I m wondering if i can use the trinket itself as a smart charge controller to charge and monitor the battery. 150v max current output. This configuration charges the battery as well as supply power to the circuit when the solar cell is producing energy. 1 charge controller as well as energy meter 2.

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

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. 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 is an atmega32u4 based synchronous mppt buck solar charge controller.

Trying out the ltc3780 dc dc buck boost module. Very safe to use as it s equipped with an automatic arc fault detection that trips a circuit when it detects. Electrical tape shrink tubing double sided foam tape solder altoids tin or other enclosure tools.
