ISO-8528-1 states that a COP-rated generator set must provide power for an unlimited number of hours per year under the agreed operating conditions subject to maintenance levels. No overload is dictated by the ISO standard. Just like the LTP rating, ISO-8528-1 allows the 24-hour average load factor to be up to the full COP rating. Typically, this is around 70% of the Prime Rating or PRP.
If you don’t need to supply power at a fixed load? Consider some of the other ISO 8528-1 Rating:
What alternative ratings are there to Continuous Power?
If the Prime Power Rating doesn’t suit your requirements, you can consider buying a generator at an Emergency Standby Power (ESP), Prime Power (PRP), or Limited-Time Running Prime (LTP) rating.
