Common issues the utility lists
- Missing one-line diagram, site plan, data sheets, fee or signed interconnection agreement
- Changes to kW nameplate, inverter make/size, VMA, in-service date or ownership after submission require new application
- Repetitive errors (wrong application level, missing signatures, multiple responses)
- Non-approved inverter (must be UL 1741 SB on PPL list)
- AC disconnect not next to and in sight of PPL meter
Gridpol’s pre-submission check covers these before we file.
