need help with Solor

Brian,
i haveBP regulator and the error messages go from E02 to E11, then another message without a number I suggest that its E12 then E13, followed by the last message without a number.

The message that I think corresponds to E12 reads:
Meaning: If there is a short circuit in the module, the moon symbol appears during the day.
Cause/Remedy: The module input is protected by an internal electronic fuse.

Note in the diagram of the Regularor the Moon symbol is in the top left corner of the screem.

I hope for your sake the unit is still under warranty and further that you disconnected the battery/load/sola panel in the corredt sequence if you did any maintenance.

I would call BP for more advice

Peter

Looks like you should be checking your panels also Brian.

Don't wait for the sun , disconnect each one and shine a desk lamp etc onto them and measure voltage , they should generate several volts each.

This only checks them without a load , so when the sun is up connect an old taillight globe etc across the panels (in turn) , each one should be able to light up the globe , after this its the regulator or connections as per other posts.
