Recommended Component List
• 7.5’ Jumper Cable
Specs: 7.5’ long, 10 AWG PV wire with
MC4 heads
Description: Pre-cut MC4 PV cabling
for connecting one pair of modules
to another pair of modules. This cable
will run from a junction box on one
PowerFit20, through the WMS wire
conduit, to the next pair of PowerFit20s.
• AP Smart System Component
RSD-S-PLC
Specs: 129 x 30 x 16 mm
Description: Allows for the rapid
shutdown of the PV system while
meeting the NEC 2017 and 2020
requirements. This device will be
attached underneath the ridge cap of
the building and connected to each row
of modules per seam.

• DOW 804
Specs: 10.1 Oz DOW 804 PV Sealant
Description: Silicone resin that will be
used to help adhere the WMS junction
box cover to the WMS wire conduit. This
will allow for a more structurally sound
install, along with creating a water-proof
sealant to prevent debris from entering
the WMS.
Other Required Components
• Inverters
Consult your installer to determine the
optimal inverter that will be compatible
with the PowerFit20 system. Attached
is a compatibility list for the AP Smart
component suggested by Sunflare. If the
AP Smart component is not being used,
one should consult the installer for the
optimal inverter based on the array size.
• Wiring for homeruns
Extra PV wiring will be needed to
complete the PowerFit20 array. This
wiring will be needed to connect
modules between seams, as well as
being used as the final homeruns going
to the inverter. Consult your installer
that the proper gauge cable is used
depending on the appropriate array size.
• MC4 Male/Female heads
Sunflare’s PowerFit20 modules use MC4
male and female connectors. MC4 male
and female connectors will be needed
for completing the excess wiring with
the proper sized PV cables.
