PhotovoltaicA class of semiconductors used for converting solar radiation into direct current electricityby way of the photovoltaic effect. PV power generation employs solar modules comprisinga number of solar cells containing such photovoltaic material.PV Array . . . . . . . . . . . . . . A combinations of PV modules making-up a PV system.Includes the associated B.O.S. to supply DC electrical power to a solar inverter. A PV Arrayis sometimes referred to as simply the array.PV Module . . . . . . . . . . . . An electro-mechanical assembly of solar cells forming a single sealed unit positive andnegative lead outputs.PV arrays (solar systems) are comprised of PV Modules.RTU . . . . . . . . . . . . . . . . . A remote terminal unit (RTU).A microprocessor-controlled electronic device that interfaces objects in the physical world to adistributed control system or SCADA (supervisory control and data acquisition system) bytransmitting telemetry data to the system, and by using messages from the supervisorysystem to control connected objects.SCADA . . . . . . . . . . . . . . . Supervisory Control and Data AcquisitionIn the context of solar inverters, refers to the computer-based industrial control systems (ICS)that monitor and control the electrical power transmission and distribution.

As used in this manual for the “bolt torque” of an electrical terminal and securing theenclosures to a concrete pad.It is the measure of the turning force on a bolt. In simple terms, it is the result of a force appliedto a lever-arm (T = F x L) to tighten an electrical terminal to a given specification. A torquewrench is used for this purpose. In this manual and on the 1500 kW inverter labels, theengineering term “pound inches” (lb-in) is provided. However, torque wrenches in the USAoften state this as “inch pounds” (in-lb) or “foot pounds” (ft-lb). See inch-pound system—USCustomary units. The SI unit is the NewtoNmeter (Nm) and is listed as the secondary value.UL . . . . . . . . . . . . . . . . . . Underwriters Laboratories Inc.Utility-Interactive Inverter .
