I have a Multiplus II 48v 5KVA. When running but with the output isolated, Venus reports 53.53v and -0.7a, giving 37.47W standby power.
Clearly greater than the specified 21w standby power.
The reported current is incorrect, a clip on meter gives 397mA which would give the correct 21W standby power. It is disappointing to find such a large discrepancy on a quality product.
This causes problems with negative DC currents which have been discussed on numerous posts.
Is there any way to zero the current meter in this unit ?
