    - Minimum voltage measuring 7.5 v, easily resolved with a small adjustment in your circuit, then how can serutilizado panel in a home made variable source. This is not a problem poi's it's designed to monitor a 12V battery. Just do the following as the input power measurement and maintenance are done by them and there is a wire doi ic 7805 which regulates the maintenance of the measuring circuit for the 7805 release ic 5v output it needs its en Entada least 7v, so it measures only starting this tension. To resolve this issue simply unplug the Vin pin of the IC 7805 and feed with an intention of not will change below 7.5 V. And then the pins before applying the voltage to be measured with a tera in common with the gnd strain IC7805


    - if you understood the proposed modification that you can mount it with a variable source
