Ratings
Prime and standby: how to read the rating
Power is stated per ISO 8528. The rating determines how many hours and at what load a unit can operate.
| Rating | Conditions | Purpose |
|---|---|---|
| Prime | unlimited hours, average load up to 70 %, 10 % overload for no more than 1 h in 12 | primary source |
| Standby | grid failure only, average load up to 80 %, less than 500 h per year, no overload | backup |
| Data center | unlimited hours at variable load | data center backup |
Range
Series by engine
The same rating is available with different engines: we select by availability, lead time, service and customer requirements.
