Permission to Operate (PTO)
After a PWRcell system has been installed, it will need to
be inspected and granted permission to operate (PTO). A
PWRcell system may be left in one of two states while it
awaits PTO:
1. System Operating: making power with 'Export
Override' turned 'on' to restrict the system from
exporting to the utility grid.
2. System Disabled: not making power with inverter
and all components in a disabled state (inverter
screen may still be illuminated).
NOTE: For systems with a battery and a protected loads
panel, the inverter's grid connection should be closed
with its 2-pole 40 A over current protection device in the
ON position and the Protected Loads Disconnect in the
inverter in the ON position. This will allow the protected
loads panel to remain powered should the system be dis-
abled awaiting PTO.
