Step 6: Close and Energize Enpower
WARNING
: Before energizing, make sure that ALL Enpower connections are properly
installed and conductors terminated.
A. Reconnect the deadfront ground cable to the grounding bar, torque as shown in the table on
the unit label (and in Step 4 of this guide), and replace the deadfront using the six reserved
screws. Tighten the cover screws using a Phillips screw driver.
WARNING
! Risk of equipment damage. Ensure that no conductors are pinched before
replacing the cover.
WARNING
! Conductors are factory provided for the generator (reserved for future use¹), AC
Combiner and Encharge. If no generator is used with the system, these conductors will not
be terminated. If the Combiner does not connect to the Enpower, these also will not be
terminated. When these wires are not terminated, they should remain stowed in the clips on
the plastic frame supporting the panel board interior and their end caps should not be
removed.
DANGER
: Risk of electric shock. There are many potential sources of voltage. Check any
Enphase Encharge battery, PV, or other generation source for voltage.
B. You must ensure that all electrical circuits external to Enpower are completed and safe
before energizing Enpower.
C. If you plan to energize Enpower without commissioning the system in the same day, OPEN
the NFT and Encharge breakers and CLOSE the other breakers in the following order:
▪
Main breaker
▪
PV breaker
▪
Generator (reserved for future use¹) breaker
▪
Load breaker
D. If you plan to commission the system, follow the instructions in ITK (Installer Toolkit) for
energizing Enpower.
E. Energize the circuit feeding the Enpower. If installed, turn the breaker feeding the Enpower to
the on position.
F. Close and secure the door of the Enpower.
Field Adjustable Trip Points
Enpower has field-adjustable voltage and frequency trip points that may need to be set, depending upon
local requirements. Only an authorized installer with the permission and following requirements of the
local electrical authorities should make adjustments.
Configure and Activate
Use the Enphase Installer Toolkit to commission the Enpower. Once connected to the Envoy, refer to the
Installer Toolkit help topics for more information.
