Generator - AC-Solar-PV, 3x15KVA Quattro and VRM

Hi!

We have the following setup at a customer of ours:

  • 3x Quattro 15000 as 3-Phase-system running ESS Assistant
  • Cerbo
  • Batteries
  • Grid-parallel Generator on AC-Out of the Quattros monitored by EM540

There seems to be no way of configuring the EM540 to be “generator” as well as in position “AC-Out”, this leads to

  • critical loads dropping to 0 as soon as the generator is running
  • the Generator is not shown on VRM and also not on the local console
  • energy on VRM is reported as coming from the generator in the sum-bars

Does anyone have a solution to this inconvenience? In Germany there are many systems like this, we have so far always set this up as “Solar”, but of course all reports are wrong and people get more and more critical.

Thank you very much!

Johannes
