NOTES
1 OPTIMIZERS PROVIDE RAPID SHUTDOWN FUNCTIONALITY REQUIRED BY NEC 690.12.
THE SPECIFIED OPTIMIZER CAN BE SUBSTITUTED WITH A P850. THIS OPTIMIZER HAS AN INPUT
VOLTAGE WINDOW WIDE ENOUGH TO ACCOMMODATE THE OUTPUT VOLTAGE RANGE OF THE
MODULE AT THE DESIGN TEMPERATURES, HAS A MAX INPUT CURRENT RATING THAT IS ABOVE THE
MAX OUTPUT CURRENT OF THE MODULE, AND A MAX POWER INPUT THAT IS ABOVE THE RATED
POWER OUTPUT OF THE MODULE.

MAX DC VOLTAGE OF ARRAY FIXED BY THE INVERTER AT 1000V REGARDLESS OF TEMPERATURE.
THE MAX DC VOLTAGE OF THE MODULE AT -23°C IS EXPECTED TO BE 48.6V (-23°C - 25°C) X -0.105V/C
+ 43.6V = 48.6V).

INVERTER IS NON-ISOLATED. NO CONDUCTOR IS SOLIDLY GROUNDED AND THEREFORE NO DC GEC
IS REQUIRED.
