Overview
U.S. grid-security concerns around inverter communications are being reframed by newly surfaced DOE analysis: lab inspections found limited documentation mismatches but no definitive evidence of malicious hidden wireless functions, while still urging operators to verify and disable unneeded protocols.

Why now
- New documents detailing DOE lab inspections were reported by pv magazine
- DOE shared its analysis with energy-sector partners after reports of undocumented communications
- Renewed focus on “as built” documentation limits and protocol verification steps
Why it matters
- May influence how inverter-communications risks are assessed in grid-security discussions
- Documentation gaps can still create uncertainty even absent evidence of malicious functions
- Highlights operator-side mitigations: verify protocols and disable what isn’t needed

Recurring claims
- DOE analysis found “no definitive evidence” of malicious wireless functions in Chinese-made solar inverters.
- DOE National Laboratories inspected approximately 30 inverters and found two cases where observed communications differed from official documentation; investigators deemed them “non-malicious” and “non-intentional.”
- DOE noted “as built” documentation may reflect only activated communications features and advised owners/operators to verify protocols and disable those not needed.
How sources frame it
- U.S. Department Of Energy (DOE): neutral
- Pv Magazine: neutral
