{Yes/No*‍/True/False} Set inverter to watt priority instead of the default var priority

DSS property name: WattPriority, DSS property index: 35

◆ yearly()

string dss::obj::PVSystem::yearly ( )

inline

Dispatch shape to use for yearly simulations.

Must be previously defined as a Loadshape object. If this is not specified, the Daily dispatch shape, if any, is repeated during Yearly solution modes. In the default dispatch mode, the PVSystem element uses this loadshape to trigger State changes.

DSS property name: yearly, DSS property index: 23

◆ yearly_obj()

dss::obj::LoadShape dss::obj::PVSystem::yearly_obj ( )

inline
