Greetings all. I recently received this back regarding an interconnection application proposing a Sunny Island 6048 and a SB7000:
"we have to rate the system at the max output of the inverters, and since that battery backup has an inverter that can export 11kW, (albeit for 3 seconds) I have to review the system for a total of 18kW." This is a new one on me. I might argue that the SB7000 is upstream of the SI6048 and really the SI6048 is the point of interconnection, so the SB7000 is irrelevant. And 3 seconds is not really continuous operation. It seems that batteryless inverters show continuous output ratings, though I know there are some that specify a larger than expected OCP for various reasons, but that is not what the utility cares about. Any insights here? Thanks, Erika REpower SOLUTIONS www.repowersolutions.com P: 216.268.2275 C: 216.402.4458
