protocols
Frame (size) Relates to the construction type of the component in question. The term is often
used in reference to a group of components that share a similar mechanical
construction.
FSCA Optional Modbus RTU adapter module
HMI Human-machine interface
IGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type widely
used in inverters due to its easy controllability and high switching frequency.
Inverter A cabinet-built device containing all inverter modules together with their control
electronics, and I/O and auxiliary components. The inverter module converts the DC
voltage to AC voltage. Its operation is controlled by switching the IGBTs.
I/O Input/Output
LCL Line filter
MEMI EMC filter board
MGND Solar array and grounding monitoring board
MIRU Solar array insulation resistance measuring unit
MPPT Maximum power point tracking. Inverter software function that automatically
operates the photovoltaic generator at its maximum power point.
