How charge controllers stop battery discharge

[AzRoute66]

Could be, but it's not. The OP was asking about how to prevent the inverter from over discharging the batteries.

Clearly I read the OPs first post and the title of this thread differently than you.

check it again:

It seems to me that in order to stop the battery from discharging at a certain point, there would have to be something to cut off the electricity between the battery and the inverter.

So how can a CC prevent over-discharge? Do I have my system wired completely wrong?

This instructable says connect the inverter to the charge controller, but that is a heavier load than a light, especially if I have my devices running on the inverter. So that doesn't seem right.
