Solar Battery Monitor

This is my first Arduino project! The primary battery in my Solar Powered Home is a series of 4, 6 volt 395 Amp-hrs deep-cycle lead acid batteries. The capacity of this 24 volt battery system is about 9.5 kwHr. This Arduino project measures the power into and out of the battery and the battery voltage and displays on a 2x16 LCD display the current charge state of the battery along with other useful information.
