Submission packages include five key sections:
Project Site
Existing System
Electrical
Storage
System Commissioning (Tesla Only)
M1 requirements are geared toward ensuring key principles of system production, safety, and customer experience.
Project Site Photos
PS1) Any additional context for site conditions/site eligibility (if applicable)
Any pre-existing damage or conditions such roof damage, altered satellite dishes, gutters, or other pre-existing damage that may be a workmanship liability in the project work area. Documentation helps protect installers from workmanship claims
Note: Existing system information is crucial to verify that the AC coupled sizing rules set by the OEM are followed. Providing all available photos is recommended, but not required. At a minimum we need to be able to determine what that AC system size is for the existing system.
Battery install crew accessing the roof is not expected or required to provide necessary photos of existing system.
Roof / Mounting System
R1) Complete Array(s) with all modules visible (if available)
Satellite imagery ‘OR’ photo from site
Complete Array(s) with all modules visible (if available)
R2) Ground Mounts/Ballasted (if applicable)
Ground Mount Equipment mounted
Ground Mount Complete Array - Front & Back
Ballasted Systems Complete Array Front & Back
R3) Balance of System on Site
Close up of existing micro or string inverter model used on site (if available)
Inverter / Combiner Photo
Equipment pullback, AC Disco (fused), Combiner/Inverter, etc.
Electrical
E1) IQ Combiner Wiring (if applicable)
Photo of open combiner box showing complete AC wiring inside of combiner box should be shown, including the breakers from the branch circuits.
E2) AC Disconnects (Fused)
Interior wiring and terminations - pull back and close up with legible fuse rating
E3) Sub panels/combiner panels (if applicable)
Interior wiring and terminations, close-up of breaker ratings, bus rating & dead-front cover off
E4) Main Breaker Rating
E5) Busbar Rating
Panel label with busbar rating clearly legible
E6) Point of Interconnection
Pull back photo required
Close up of taps or back feed breaker (size clearly legible)
E7) Balance of System (Pullback)
E8) Consumption Meters
Photo of consumption meters installed to manufacturer specifications
Close up photo of arrows facing the correct direction
Above: Enphase Examples
Above: Tesla Examples
E9) Interconnection Agreement
Existing system interconnection agreement with the utility provider
Enphase Encharge (10P photo examples)
Close up of serial numbers, model, size; Internal wiring/connections; Battery
System Controller Wiring & Deadfront (Gateway); Battery CTs;
Battery comms cable terminations and installation must be per manufacturer specifications
Photos must clearly show both cable ends terminated (in every component), ensuring the drain wire is landed on one end only
Tesla Powerwall 3 Example photos
Close up BUG Internal wiring/connections; Battery CT
Close up of battery label & serial numbers, model, and size
Battery wiring: terminals and RSD; communication cable at Backup switch
Battery Wiring: terminals; communication cable at Battery w/ Drain wire
Solar & Consumption Meters
Consumption and Production Meters
Consumption CTs need to capture ALL home consumption
Solar Production CTs need to capture ALL existing and new energy production (if applicable & product specific - Example: Tesla Powerwall 3 requires Tesla Remote Meter Solar CT for existing solar)
Close up photo of arrows facing the correct direction
There are no exceptions since the battery performance is reliant on these energy measurements
SC1) Commissioning (Tesla only)
Commissioning of the system should be completed prior to leaving the site. System should be fully operational with all devices paired, active communication, reporting production and consumption data including cellular connection signal
Tesla screenshots should show 'LightReach' added as partner, inverter & CTs enabled, networking connected to Cellular. Include operations settings page for panel current limit & PCS settings
