Panel display different (1 Viewer)

[Glynn]

Anyone else have this, the voltage displayed on the panel over the door is lower than what is measured with a meter at the leisure battery ?. Is there any calibration possible ?.

Also, I have new Elecsol batteries and from fully charged if I switch on all the lights & TV etc the panel will show " 11.8 v or so Fair " rather too quickly.

Any ideas ?.

depends on which panel you have but i would check the connections to the battery are clean and tight.

lights and tv are placing a load on the battery giving a false reading on an over sensitive panel gauge.

as an example.....a car battery will show around 9v when cranking the engine (loaded) but will rise back to 12.6v within a second or two when you stop cranking (at rest)

battery meters should be checked 'off load' for a true state of charge.
