i am planning for an installation with 3x5kVA Multiplus II with EM24 grid meter and loads on AC-in as well as on AC-out. Like this:
I came across these threads, where users notice quite slow response to loads, if the ET112 grid meter is installed:
I have some questions to this:
One suggested solution was to place the loads behind the Multiplus II at AC-out1 and AC-out2.
OK, thats not a problem. All my loads, that would require fast response would be connected to AC-out anyhow. So.... does it mean, with EM24 connected and set as grid-meter, the loads on AC-in will be handled slower, but the loads on AC-out STILL would be handled fast?
OR.... will all loads be handled slower, once a EM24 grid meter is installed? regardless if connected to AC-out or AC-in??
Some more detail questions:
1. Will the EM24 Ethernet or EM24 RS485 version work better for having faster response? Or is there no difference?
2. Is it better for faster response to have an external Cerbo GX or instead better use a Multiplus II with internal GX?
hope you can help to clarify!
