What is a DC inverter & converter?
The standard covers requirements for inverter and converter equipment that are intended to convert DC power from a renewable energy source into AC power that can be used by the electrical grid or other electrical loads.
What standards govern inverters?
Currently the main standards which govern inverters in the IEEE 1547 “Standard for Interconnecting Distributed Resources with Electric Power Systems” and UL 1741 “Standard for Safety for Inverters, Converters, Controllers and Interconnection System Equipment for Use with Distributed Energy Resources.”
What is an advanced inverter?
Advanced inverters have the capacity to supply or absorb reactive power, and to control and modulate frequency and voltage. Presently, capacitors and voltage regulators are installed to offset reactive power produced by inductive loads on distribution feeders.
