Existing system (battery retrofit / add-on)
PV modules
Panel library
Pick a panel to auto-fill the specs below from its datasheet, or enter manually.
Multi-SKU arrays: load a preset or extend via API JSON. UI v1 supports primary module type.
Equipment — inverters & batteries
Add multiple units. Upload a spec PDF to auto-fill fields from the datasheet (OCR of the PDF text layer), pick from your saved library, or enter manually. Review auto-filled values before saving.
Inverters
Batteries / ESS
Roof planes + stringing
This is what makes structural superior: enter real plane dimensions (eave width × ridge depth in plan feet). Modules pack inside fire setbacks automatically.
Roof plane #1
Roof plane #2 (optional — set modules to 0 to skip)
DC strings
