Question:
Are Photo-voltaic arrays allowed to be interconnected to emergency generators under NEC 700? My question concerns a 500 KW generator in a larger middle school.
Greg Evers
A
Answer:
Hey Greg thanks for your question. Yes, PV systems are allowed to be interconnected with other sources if installed to meet Parts 1 & 2 of Article 705 as stated in 690.59. Table 705.3 includes emergency systems as covered in Article 700. Middle school reminds me of visits to the principal's office and detention.
