DC injection limitation

ID: func:dc-injection-limitation
IRI: https://solarlattice.org/kb/func/dc-injection-limitation
Status: active
Also known as: DC current injection limit, Limitation of dc injection, DC current injection
Category: Protection
Function kind: protection

DC injection limitation keeps an inverter-based generator from pushing direct current into the AC grid above a small fraction of its rated output current. The Sungrow SG250HX-US datasheet lists DC current injection below 0.5% of rated current.
