“We were asked to add protective relays on two large solar PV systems at the last minute, at commercial buildings in an office park north of Boston. This was a first-time experience for the electric utility, and they gave us very strict requirements for the two sites. Day Ahead Instrumentation responded to the challenge.”
“We were able to stay on schedule for the interconnection at both sites. DAI provided the equipment exactly as it had been designed, and arranged all the programming and testing. The protective relays are working as planned, and we have had no issues with the sites.”
We worked very closely with DAI on our most complex protective relay project to date, and they delivered at every step of the way, on time and on budget. I highly recommend working with DAI on any customized relay solution needed for DG projects.
