What is an EPC inverter?

EPC’s inverters are designed for the energy storage and PV market and include advanced functionality as standard, that enable participation in grid ancillary services like frequency regulation, voltage control and black start, with leading response time.

What is the difference between EPC materials & owner services?

Materials include all construction materials associated with the EPC scope of work, material freight costs, and consumables during construction. Owner’s services include project development, studies, permitting, legal, owner’s project management, owner’s engineering, and owner’s start-up and commissioning costs.

What type of inverter does a PV system use?

This system uses one 2500-kW central inverter with one integrated 2.5 MVA medium-voltage transformer within each PV block. Inverters that are skidded with a medium-voltage transformer (either via internal or external integration) are referred to as power conversion stations and are typically sold as a cohesive unit from the inverter manufacturer.

What is a battery storage inverter?

Battery storage inverters also allow the batteries to be charged by either the solar array or the grid. This facility uses 150 MW of solar inverters plus 50 MW of battery inverters. Battery inverters are typically more expensive than solar inverters. 2019).

What is a DC-coupled solar inverter?

CASE DESCRIPTION This case is based on a nominal 150 MWAC solar photovoltaic (PV) plant with 200 MWh of lithium-ion battery storage that is DC-coupled. The DC-coupling architecture refers to a design in which the PV and battery components are coupled on DC side (plant side) of the inverter.

What are EPC fees?

EPC fees are applied to the sum of direct and indirect costs. 2. Owner’s costs include project development, studies, permitting, legal, owner’s project management, owner’s engineering, and owner’s start-up and commissioning costs. Other owner’s costs include electrical interconnection costs, gas interconnection costs, and land acquisition costs.
