My off-grid solar installation in Colorado now needs a complete DORA inspection submittal. I already have the site plans, but the packet still lacks the detailed electrical portion that DORA reviewers require under current electrical safety codes. Scope of work • Draft full, code-compliant electrical one line diagram that covers every major component: 5 kW rooftop PV array with MLPE rapid-shutdown devices, a 48 V lithium-ion battery bank, an all-in-one hybrid inverter/charger, and a backup propane generator with auto-start. • Produce a narrative of operations and a one-line diagram referencing the applicable NEC articles adopted by Colorado. • Include conductor, OCPD and grounding calculations, equipment spec sheets, placard schedule, and any rapid-shutdown verification details. • Package everything as a clean, printable PDF set ready for direct upload to the DORA portal; no further formatting on my side should be necessary. Acceptance criteria 1. Drawings and documents clearly show compliance with Colorado-adopted NEC electrical safety codes and the DORA checklist. 2. All components match the site plan locations and physical constraints already provided. 3. I’ll supply the review and feedback as the work proceeds. I have cut sheets on all the major components. Provide the finished packet and editable source files (DWG or similar) within the agreed timeline so I can schedule the official inspection.

Hello, I have experience preparing solar PV electrical permit packages, including one-line diagrams, conductor sizing, OCPD schedules, grounding notes, placards, battery systems, and generator integration. I am interested in this project because it needs a complete, inspection-ready DORA submittal with a clear code trail. I will review your site plans and equipment cut sheets, then draft the electrical one-line for the 5 kW PV array, MLPE rapid shutdown, 48 V battery bank, hybrid inverter/charger, and propane generator auto-start system. I will prepare the operating narrative, NEC references, calculations, spec sheet index, placard schedule, and rapid-shutdown notes in a clean PDF packet. I will also provide editable DWG source files and make revisions based on your review before final upload. Thanks for reading my proposal. Edwin

Hello, I reviewed your Colorado DORA solar submittal requirements, and the main challenge is coordinating the electrical documentation, code references, and system details into a complete package that satisfies inspection requirements. I would focus on developing a clear one-line diagram, electrical calculations, equipment documentation, grounding details, placard information, and properly organized submission files based on the provided system components and site constraints. I have worked on electrical documentation, technical drawings, and engineering support packages and can share relevant examples once we connect in chat. Also a quick question, has the equipment layout already been finalized on the site plans, or should the electrical drawings also verify component placement and routing details? Best Regards, Atik
