Battery Bank Analyzer

This is a project to monitor a Battery Bank (Lithium Battery Packs) in a solar installation. It traces current individually for each Battery Pack. It also communicates with solar charger and calculates live values of power going to home and battery bank. It includes a web server with charts, internal historical data, and optionally, uploads data to Thingspeak and Blynk.

This project is part of an experiment, to check the behaviour and lifetime of Li-ion battery packs (BMS included) connected in parallel in a solar installation. Lithium Chemistry used is not LiFePo4 3.65V/Cell, recommended for solar installations, but regular Li-ion batteries 4.2V/Cell, with more capacity and also risks. As can be seen in photos Battery Packs are inside safety bags bellow Battery Analyzer and everything is in the roof.
