AC OUT strange readings on Multi RS Solar ...

Hello All,

I've just bought an Multi RS Solar 48/6000 dual tracker (PMR482602020).

I didn't installed it yet, but for testing purposes, I've connected the grid to AC IN. The PV1, PV2 and AC OUT were left open circuit.

Power it up and then connected to it with VictronConnect App over bluetooth.

The App says around 25W on the AC IN, which is normal, because of the device idle consumption, right?

But on the AC OUT it says - (minus) 15W.

Is this normal?

Thanks in advance for any response!

Multi RS

Don't run an inverter without a battery connected.

It is not supported and things will not work as expected.

I understand and thanks for answering.

But at some point, the battery BMS might decide to disconnect the battery and then there will be the same situation, no battery connected....

It is likely only showing readings like that since there isn't a battery and no load.

The metering is also inaccurate for tiny or non existent loads, it will be fine when properly configured.
