When the volt-watt function is enabled, the grid voltage is within 100%~106% (V
Output Voltage, the inverter output power (Pn) may reach 100%. When the grid voltage is lower than the Rated
Output Voltage or more than 106% V
will begin to derate, shown in Figure 10-3-2.

Reactive Power Capability
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 69.5/60.2A/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.
