Volt Sensor Holder v1

Summery
====================
This volt sensor holder is to hold the volt sensor that disconnects my battery bank of my solar PV system when the battery is full or to a level of charge (lower limit) that is user settable.

The use of the volt sensor is for over charging and to only discharge 50% of my battery bank.
It also sends a signal to a relay that send the power from the solar panels to a inverter when the battery is full so I don't waste any energy that I have collected via the system.


The Relay I use
