Here's an update:
The Sinergex inverter
starts a warning tone at 10.7 volts and shuts down at 10 volts... Not 11.7 as I previously stated. At 6 1/2 hours, the tone was on, but the AC was still running. I shut it off, so the gauge probably said 10.7
I was a bit occupied with catching Mahi, so I didn't spend to much time down there.
Yesterday, I ran the AC for 3 hours non stop. The volt meter showed 12 volts when I shut it down. I found a schematic that shows the starboard engine
supplies power to the AC battery
, but here's the weird part. I ran the boat for another 4 hours and the gauge stayed at 12 volts. If the starboard alternator
the AC batteries, shouldn't it have come up from 12 volts?
Now, the starboard wet cell battery is a bit old, and it may of been taking priority after I shut down the AC system... But I would think it would of gone up a little.
Thanks for the info on the charger
... How much do these things cost?
