12v outlets and CP read 11.6 but batteries 13v

[Tompoole]

Hi

Odd issue with t6 California, any help welcome.

Batteries new and at 13v
12v outlets only register 11.6 and so does control panel.? Where do I start?

On hook up 12v outlets register a charge but don’t register when solar panel is charging

Bit lost

When you say batteries are at 13v is that connected and at the same time as you are measuring the sockets? If so that is beyond odd! . Sounds like there is some load on the system if you have a voltage drop. Is the fridge / lights or anything else on.

Measured battery with meter and shows 13v , 12v sockets show only 11.6 and so does control panel? If I plug in ehu it charges batteries and 12v outlets register a lets and control panel registers the charge ?

I presume you measured the battery voltage between +tve and -tve poles?
What is the voltage between +tve pole and Earth point or chassis?
When on EHU or engine running does the Control Panel voltage rise to 14.4 v ?

It sounds possible that you have a high resistance connection and as it’s affecting the sockets and the Control Panel as well I would check ALL battery connections, both +tve and -tve Pole connections but also the Chassis connections of the -tve leads for both batteries.
