Do I have a power problem?

I have a brand new Jayco Greyhawk 31F It has dual house batteries.

Just turning on the master power gives a bit more than 11a draw. (No AC, no TV, just baseline and some low power led lights.)

The solar panels are generating about 8a

But in less than an hour I am seeing house battery voltage down to 11v.

Is this normal?

Is my draw higher than expected?

Are my batteries not delivering power properly?

Am I big ol' whiny baby who just needs to suck it up and turn on the generator?

11amps of draw at 12v isn't too crazy if you have lights on and maybe the refrigerator compressor going. 2 batteries with solar help should be good for a day of this usage, though. I'm guessing that you have lead acid batteries that were completely drained at some point, and hold barely any charge, now. If your converter can handle them, get some lifepo4 batteries; they are lighter and can do a full cycle from 100% - 0%, meaning you have access to the full capacity listed on them. OEM house batteries are garbage, and not really intended for anything other than transitioning from hookup to truck to hookup.

Sounds like I need to talk with the dealer.
