Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
