Ron, our Xantrex inverter on the wing behind the drivers seat tell me the volt when I turn it on. Don't you have one of these also?
No Tom, we don't. Our older Tripp-Lite's switch panel under the fridge has no meter reading. Just LEDs and a switch for "Auto Invert" & "Line Charge Only".
Here is a picture of our Tripp-Lite control panel, the panel to the right. You can see the green/yellow/red LEDs along each side. The lights work as follows.
- Green = Good
- Green/Yellow = Not As Good (in reality, the batteries are already severely drained)
- Yellow - Fair (in reality you waited too long)
- Yellow/Red = About To Die (you'll need days on a slow charge to bring them back to a usable but permanently weaker condition)
- Red = You Killed The Batteries (it's over, just buy new batteries)
This is not a good method for monitoring the health of our batteries. On top of that, I only turn on the inverter when we want to use inverted 110v which is not very often. So this monitor is nearly useless to us, hence I want to install a voltmeter that is always on and in plain sight.
