1. Introduction
1.1 Design Features
The PVP250kW, PVP260kW and PVP260kW-LV Inverters are designed to act
exclusively as a grid-tied inverter for photovoltaic (PV) systems. This means the inverter
must be tied to the utility grid and a photovoltaic system in order to operate properly and
it is not suitable for any other applications (such as a battery back-up or wind powered
systems). The inverter contains everything needed to convert the DC voltage generated
by a solar array into AC electrical power. Because the inverter is tied to a local utility
source, if local electrical load exceeds the power generated by the solar array, the
grid automatically supplies the additional electricity needed. Likewise, if the inverter
produces more power than is needed, it feeds the excess power back into the electrical
grid.
This manual provides all the information necessary to successfully install and operate the
PVP250kW and PVP260kW Inverters.
PVP250kW and PVP260kW Models
The PVP250kW model inverter can be factory congured with either a three-phase
600VAC or three-phase 480VAC output.
Two models of the PVP260kW are available: the PVP260kW and the PVP260kW-LV.
The PVP260kW-LV is identical to the PVP260kW except that it is congured for low
voltage 265VDC input.
Throughout the remainder of this manual the models are referred to as the PVP250kW
and the PVP260kW. All information applies to each model unless stated otherwise.
Easy Installation
The PVP250kW and PVP260kW Inverters are built for easy installation. To minimize
installation efforts, these inverters feature an integrated isolation transformer and
integrated AC and DC disconnects in a compact single cabinet. The units can be ordered
with a range of DC subcombiner designs for maximum adaptability for the desired
system operating scheme.
Simple, Innovative Design
The PVP250kW and PVP260kW Inverters are a fully integrated solution with standard
integrated data monitoring. Their modular design enables rapid eld service and
upgrades. The inverters can quickly and easily be installed in any preferred location,
indoors or out.
Adaptability
The PVP250kW and PVP260kW Inverters’ DC Maximum Power Point Tracking (MPPT)
range is 295VDC to 595VDC standard, with an optional 265 VDC input on the LV
model. The maximum input voltage is 600VDC.
