Versatility
The PVP250kW and PVP260kW Inverters are designed for exibility. They can be used
for a range of commercial applications and they can accommodate most PV system
congurations.
1.2 Product Characteristics
See
Appendix A - Specications
for the product specications information.
1.3 Product Features
The design of the PVP250kW and PVP260kW Inverters includes:
• Redundant cooling blowers with fault detection
• Anti-islanding protection
• EMI input and output ltration
• Field-selectable voltage and frequency trip points
• Remote monitoring
Redundant Cooling System
The PVP250kW and PVP260kW Inverters are equipped with a redundant cooling system.
The variable speed blowers with built-in backup capabilities enable the units to remain
fully ventilated even if one of the blowers should fail. Blower status is reported as a
warning shown on the display and through remote monitoring.
Anti-islanding Protection
An advanced anti-islanding monitoring function prevents the inverters from feeding
power to the utility grid in the event of a utility outage.
EMI Input/Output Filters
The PVP250kW and PVP260kW Inverters utilize EMI input and output lters to prevent
electromagnetic interference.
AC Overcurrent Protection
The PVP250kW and PVP260kW Inverters current monitoring system constantly
monitors the AC current within the unit, limiting the inverter current output.
Remote Monitoring in a Dedicated Monitoring Section
All PV Powered commercial inverters come with a standard Ethernet data acquisition
and communications interface module. With a high speed connection, this module can
provide PV system performance data in the following ways:
1. Subscribe to the standard monitoring service on the mypvpower.com web site. This
recommended method allows the user to track the PV system and inverter informa-
tion online. This secure web site is provided by PV Powered and the Basic Monitor-
ing Service is available to all registered users.
2. Provide data to incentive-based performance monitoring and reporting programs for
third parties.
