experts have identified these undocumented devices in solar power inverters and batteries from multiple Chinese suppliers during detailed security assessments of grid-connected equipment. Over the past nine months, U.
oped by vendors and national laboratories was conducted in 2023. The results of the survey are presented in this report with the current status of commercial microgrid controllers analyzed, potenti l esearch gaps.
Electrical test results: polarity, continuity, insulation resistance, Voc/Isc per string, functional checks, and inverter start-up. Performance baseline: initial operating data and notes on irradiance and temperature conditions.
