• CEC Efficiency: CEC Efficiency is the California Energy Commission Efficiency rating, a
performance rating for inverters based on the real environment that a system will be in.
• CSA: Abbreviation for the Canadian Standards Association.
• CT: Abbreviation for current transformer.
• DC: Abbreviation for Direct Current.
• De-rating: A controlled reduction in performance, usually dependent on component
temperatures. De-rating is initiated in order to avoid the shutting down of the complete
system.
• EMC: The Electro-Magnetic Compatibility (EMC) concerns the technical and legal basics
of the mutual influencing of electrical devices through electromagnetic fields caused by
them in electrical engineering.
• ESS (Energy Storage System): The complete combination of inverter, battery pack,
panels, and BOS is called an Energy Storage System.
• FCC: Abbreviation for Federal Communications Commission.
• Firmware: Firmware is software that is stored in a processor in various electronic devices,
such as H6. Firmware is stored in Flash memory or an EEPROM chip.
• Floating system: If the main electrical connections are not grounded in the system then it
is considered as floating. There could be grounding of the chassis to avoid electrical
shock.
• GET: Abbreviation for Grounding Electrode Connector.
• GND: Abbreviation for Ground.
• Grid-Tied: A PV system that is connected to the utility grid. Also called On-grid.
• Hybrid Inverter: an inverter that can function as PV inverter and storage inverter. Also
called multi-mode inverter.
• IEEE: The Institute of Electrical and Electronics Engineers is an international non-profit,
professional organization for the advancement of technology related to electricity.
• IMI: Abbreviation for Isolation Monitor Interrupter.
• Initialization: Under initialization is the part of the loading process of a program with
initial values.
• ISC: Abbreviation for Short Circuit Current.
• Inverter: A device for converting the direct current (DC) from the PV array or battery
pack into alternating current (AC), which is necessary for the connection of most devices
and especially for the feed-in of green energy into an existing transmission line. Inverters
for PV systems usually include one or more MPP trackers, store operating data and
monitor the grid connections of the PV system.
