1250VDC System

[s4if]

Hello,

Is there a way for me to make simulations for DC voltages higher than 1000V? There are inverters from GE in PVsyst that allow for 1275VDC input but i can't use them because the program won't allow me to cross the 1000V mark.

Best Regards,

S4if.

All the PV modules are specified for a 1000 V voltage limit in the array, by respect to ground (IEC norm).

Therefore if you want to do that you should use very special modules, not available on the market.

However this inverter is probably specified for using 2 symmetrical arrays (by respect to the ground voltage).

In this case you should define the inverter as a "Bipolar" inverter, in the "Sizes" page, "Technology specificities".

See the Advanced Energy inverters as an example.
