Low battery shut-off (or at least a warning)
Is there a way to install a shut-off mechanism when the house battery reaches a predetermined low voltage? In most situations I'd rather lose the battery functions (including the refrigerator) than I would the battery itself. It's mostly due to accidental failure to turn off the master but could apply to over-discharge during normal operations, particularly if there was a intermediate warning sound.
I recently accidentally left the master switch on for a prolonged period and fear I may have damaged the AGM battery. (I'm having it tested. The load test was fine, but it wasn't at full charge when I dropped it off.)
