I have a Whole House Generator and I just installed a Solar Battery Charger. What I am trying to design is to be able to read the Voltage from the Solar Panel and from the Battery. I want to be able to read each source ( Solar Panel & Battery ) separately using only one panel mounted DC Voltmeter and one switch if possible. I want the meter to be off until you flip the switch. The Solar Panel will alway be charging the Battery until you read the volts on the meter.

I hope someone can help.

Thank You,
Ned

For starters, you need a double pole, 3 position switch.

In Position "1" - pole 1 connects the solar cell to the battery. Probably with a diode or whatever, for night time when the battery voltage exceeds solar cell voltage. Pole 2 is not connected.

In Position "2" - pole 1 disconnects the solar cell. Pole 2 connects the cell to the meter.

In Position "3" - pole 1 disconnects the solar cell. Pole 2 connects the Battery to the meter.

Hope that helps ...
