• Fences and Gates to be labeled on plans
• Photo of existing meter location, from Site Capture, required
• Azimuth and tilt of each array needs to be called out.

SLD Reqs

Relay Meter Orientation = Under/Over

• Line Side Tap in a lockable junction box between the utility meter and Utility feeder lines is the ONLY acceptable POI = Inverter>AC Disco>Bottom of PM> Top of PM>Tap Box POI>Out to Utility. Breaker tie in is not permitted, unless batteries are included
• The PV Meter should be wired bottom toward inverter, top toward utility
• The Utility Meter should be wired bottom toward MSP, top toward utility feed
• Do Not Use piercing taps
• Neutral must be bonded in the tap can
• 2 ground rods required at main service panel as well as a new ground rod attached to the fused AC disconnect. (Drop down on CAD Template has this pre selected.)
• GEC require #6 AWG min
• The AC disconnect is required to be bonded to the neutral and have a GEC. (See "AC Disconnect Grounding" in file section)
• Do not show EGC in the PV Meter
• EXISTING ENPHASE MICROINVERTER SYSTEMS - If the project has an existing Enphase microinverter system DO NOT add new breakers to the existing Enphase Combiner Box. A new combiner box will be required for the new system's breakers. The existing Combiner Box and the new Combiner Box will lead to a new PV Load Center. The new PV Load center will lead to the new AC Disco.

• Show conduit from tap box connecting with the line side conduit of the utility meter.
• Vertical installation not acceptable, equipment layout diagram must be accurate and to scale using an Architectural scale.
• Show dimension of each piece of BOS equipment relative to grade. PV Meter to be minimum 4' above grade.
• Show dimensions of the tap enclosure on BOS Elevation. The height must be twice the depth, with a minimum height of 12”

Battery Jobs

• Adhere to EG 14 or EG15 as provided by the Utility (see files section)
• Battery Projects do NOT require production meters
