Hi there!
I am planning an ESS three phase system, and would like to know if it is possible to place three phase loads between the meter (ET340 in this case) and the 3 Multiplus II (one per each phase).
The order of the components would be as follows (from mains to loads):
AC 3 phase Mains (+ Utility meter + mains protections). 230V between phases (127 V between phase and neutral)
|
ET340
|
-------> 3 phase motor (elevator)
|
Autotransformer (230V/400V)
|
Multiplus II + Multiplus II + Multiplus II
|
<----------- 3 phase Fronius Symo
|
RCD & ThMg breaker + RCD & ThMg breaker + RCD & ThMg breaker
Loads (mono) + Loads (mono) + Loads (mono)
My main doubt is whether or not is it possible to place a 3 phase load between the ET340 meter and 3 Multiplus II, so normal funcioning of the ESS system does not become affected in terms of metering load and production, as well as orchestrating the overall ESS system.
Thanks !!!
