Installation and Operation Guide SOLECTRIA® PVI 25TL-208, 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 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
dc
Maximum Power Voltage Range for each model (see graphs). For example, for the 25TL the Maximum Power
Voltage Range is 480-850Vdc. It is recommended to design the PV array so that the source circuits will have a V
mp
that lies within the Maximum Power Voltage Range. If this is not possible, please refer to Figure 10-1, Figure 10-2,
and Figure 10-3 to see the effect of V
on output power.
