INSTALLATION WORk
SRS utilizes single point integrated grounding. Use a minimum #10 AWG ground wire for this purpose. The equipment
grounding conductor will continue down to the DC disconnect, inverter and AC service equipment.
Use # 10 x 1" stainless steel machine screw,
lock washer and nut.

Continuous equipment grounding of modules
and mounting system is provided by the Module
Mounting Clips.
Ensure that every sub array is grounded and that
during replacement or repair, removal of the last
module breaks the ground path.
This can be achieved by installing grounding hardware
on either end of bottom rails.
1. Install outdoor rated ground lugs or ring terminals
with ground wire (per above drawings). Use the
marked ground hole on either end of the rail.
2. Connect a minimum # 10 AWG solid conductor
copper, ground wire to the ground lug or ring
terminal.
3. Connect the end of the equipment grounding
conductor in the array junction box
4. Connect the equipment grounding conductor
to the DC disconnect, inverter, and AC service
equipment.
5. Connect the ground wire from the inverter to a
grounding electrode.
