I'm updating my interconnect agreement to add batteries to my Sol-Ark 15k. The form asks for maximum ramp rate in KW/s for battery charge and discharge. I have no idea what that would be. It's not in the Sol-Ark spec sheet. I've sent an enquiry to Sol-Ark. Has anyone come across this? If you are using Power Clerk to submit an interconnect application, you will probably be confronted with this question.
