Hi,

has solar 2 been working OK for a while and has just stopped working?

Do you get any output at different times of the day?

Hello @bladerunnervf,

The unit was running normally with the two solar ports. No, it doesn't give any output ay any time at all.

On the face of it, it sounds like a failure.

Is there any logging of status data or any error codes?

Can u get your installer to login and check it remotely?
