The drawing must cover every component—from module strings and combiner boxes to inverters, AC/DC disconnects, grounding, metering, and the final tie-in to the building’s main distribution board—so the utility and local inspector can approve it without revisions. Because this is a commercial installation, please apply the latest NEC and any relevant local codes. I’m still finalising the exact array size, but expect something in the 50–100 kW range; your input on optimal capacity and equipment selection is welcome. Deliverables • Editable DWG (AutoCAD) and a stamped PDF ready for submission • All devices labelled with ratings, pa...
I need an accurate and professional electrical wiring diagram for my installed DIY grid-tied solar array system. The deliverables should include: - Service panel connections - Grounding schedule - Details required for electrical inspector approval This involves solar panels and an inverter, so experience in designing layouts and knowledge of local inspection requirements is essential.
We are seeking an experienced electrical engineer to create four comprehensive study reports: Steady State Study Report, Dynamic Study Report, Power Quality and Protection Study Report, and Earthing Study Report. The ideal candidate will have a strong background in electrical engineering and excellent report writing skills. The reports should be detailed and accurate, providing insights into the electrical systems and infrastructure. PSCAD for dynamic studies and PSS SINCAL for steady state, protection, power quality, and earthing studies. 1. Steady State Study Report Covering load flow, voltage profile, thermal loading, reactive power performance, and contingency review. 2. Dynamic Study Report Using PSCAD, including assessment of plant response to disturbances, fault ride-through perf...
I need a reliable designer who can turn around 5–10 residential PV layouts every day in Pylon. Each file must: • Model any structures or trees that may cast shade • Optimise panel placement, stringing and MPPT allocation • Assign the specified inverter and battery from the drop-down library • Add any extra line items (e.g. Iboost or EPS) by selecting the pre-populated option Cable routes, single-line diagrams and other electrical details are handled in-house, so you can focus purely on the Pylon design environment. Typical site data, design specs and required naming conventions will be supplied with every request, and I’m happy to standardise a template to speed your workflow. In your bid tell me: 1. Your price per completed design file 2. H...
