# description
Typed schema for grid-connected power-electronics inverter energy resources (type = INVERTER). Captures IEEE 1547-2018 ride-through categories, operating mode, and reactive/frequency-support capabilities per SunSpec DER Models 702-714. CIM: PowerElectronicsConnection (IEC 61970-302). Common fields inherited from EnergyResourceCommon/v1.0.

# allOf[].properties.type.description
Asset-class discriminator. Must be "INVERTER". CIM: PowerElectronicsConnection (IEC 61970-302).

# $defs.EnergyResourceInverterAttributes.allOf[].description
Attributes for INVERTER resources. Common fields inherited. IEEE 1547-2018 / SunSpec inverter-specific fields below.

# $defs.EnergyResourceInverterAttributes.allOf[].properties.ratedApparentPowerKva.description
Rated apparent power in kVA. SunSpec Model 702 maxVA. CIM: PowerElectronicsConnection.ratedS.

# $defs.EnergyResourceInverterAttributes.allOf[].properties.maxReactivePowerKvar.description
Maximum reactive power injection (leading / over-excited), kVAr. SunSpec Model 702 maxVar. CIM: PowerElectronicsConnection.maxQ.

# $defs.EnergyResourceInverterAttributes.allOf[].properties.minReactivePowerKvar.description
Maximum reactive power absorption (lagging / under-excited), kVAr. Usually expressed as a negative value. SunSpec Model 702 maxVarNeg. CIM: PowerElectronicsConnection.minQ.

# $defs.EnergyResourceInverterAttributes.allOf[].properties.rideThroughCategory.description
IEEE 1547-2018 abnormal operating performance category. CategoryI: basic. CategoryII: enhanced for distribution-connected DER. CategoryIII: advanced for large/transmission-connected DER.

# $defs.EnergyResourceInverterAttributes.allOf[].properties.operatingMode.description
Inverter grid-interaction mode. GridFollowing: PLL-based sync to grid. GridForming: establishes own V/f reference (microgrid islanding, black-start). Standby: energised but not injecting. CIM: PowerElectronicsConnection.inverterMode.

# $defs.EnergyResourceInverterAttributes.allOf[].properties.voltVarEnabled.description
