    Installation and Operation Guide SOLECTRIA® PVI 25TL-208, PVI 36TL-480-V2, PVI 50TL-480 and PVI 60TL-480 Production Graphs The following sections illustrate the inverter production/derating in terms of DC voltage, ambient temperature, altitude and grid voltage. DC Voltage Derating Graph While the Solectria PVI 25TL-208, PVI-36TL-480-V2, PVI 50TL-480, and PVI 60TL-480 inverter has the ability to operate from 200-950 V (Operating Voltage Range), it will only be able to output full rated power for its model from a limited Maximum Power Voltage Range for each model (see graphs).

When the grid voltage is lower than the Rated Output Voltage or more than 106% V , the inverter will limit the AC Output Current and the output power (Pn) will begin to derate, shown in Figure 10-3-2.
  • Page 135 The Reactive Power Overload function is available for the PVI 50/60TL-480 and is disabled by factory default (Max. AC Apparent Power is 25/50/60kVA and Max. AC Output Current is 69.5A/60.2A/72.2A). For the PVI 25TL-208, only refer to the blue curve. Contact Yaskawa Solectria Solar Customer Service if you want to enable the Reactive Power Overload function.
