Input current on Multiplus II is always 0 A.

Hello, I have an active input connected to the Multiplus II but the multiplus does not read the input current. It does read the input voltage and output current. See image below:

Why could this be? Could it be that the current transducer is broken?

Best regards

@sebastia@phoenixone.co

Has it connected (closed its relay) on the input?

How is it programmed? With virtual switch (ve config) or maybe Conditional AC connect (Victron connect)

A simpler check on the GX under

devices list - inverter - switch state

and see if it is 'inverter only' set there.

I can see the inverter seems to be synchronised to the input.

Do you have the external CT? Is the inverter set to use its internal metering system is system set up?

It doesn't have any external current transducer (CT). I will check the setup with the VEConfig Tool if it is set to use its metering system. Thank you.

I have checked the configuration, and yes, it is set to use its internal metering system. Here the configuration:

have you check that the at wire link is in place on your multi plus-II look ware external CT wired for wired remote CT or if you have older multi plus-II with plug in type CT contact your Victron suppler for help as older multi plus-II with plug in type CT had problem with CT socket
