6.8. Requirements for transformers
6.8.1. Grid connection transformer
CAUTION
These units must be connected to a transformer with the neutral of the low-voltage side isolated, thus
generating an IT grid.
This section lists the technical specifications of the grid connection transformer which converts the medium or
high supply voltage to the operating voltage of the unit.
1. The transformer’s power must be greater than the sum of the power ratings of the connected inverters,
keeping in mind the locations environmental conditions and height.
2.
If connecting the equipment to the transformer's same low voltage winding, these must be synchronized.
These
equipment have all the necessary elements to synchronize up to four inverters.
