4G6: DC Voltmeter
In the DC Breaker Panel is a voltmeter with a
battery selector switch.
When the photo was taken, the switch was in the
“house” position, and the meter showed 13.2 volts.
As the scale indicates,
around 11.0 volts (red) is considered “dead”;
12.8 volts (100%) is a fully-charged, unused
battery;
13.2 volts is a battery getting a “float” charge to
keep it charged;
14.2 volts is a battery being “bulk” charged.
The switch positions are:
1 = The House Battery Bank
2 = The Starting Bank
3 = 20KW Generator Starting Battery
4 = 8KW Generator Starting Battery
