1 General Information
The Protect PV.250 is a solar inverter (INV) that feeds the electri-
cal energy produced by the PV cells into an AC voltage mains.
The Protect PV.250 is available in two basic versions:
- For feeding into a low-voltage mains
(e.g. 400 VAC)
- For feeding into a medium-voltage mains
(e.g. 10 kV; 20 kV; 33 kV)
The required mains transformer is not supplied with either version
of the unit and can be ordered as an extra if necessary.
It is possible to combine two Protect PV.250 units to create a
500 kW system.
With the low-voltage version, each Protect PV.250 has its own iso-
lating transformer, whereas a shared isolating transformer can be
used for the medium-voltage version (in this case, each Protect
PV.250 has an electrically isolated low-voltage connection).
500 kW systems can be made to support "partner operation" to in-
crease their efficiency.
The nameplate, featuring all relevant data, can be found on the AC
panel on the inside of the door.
