What does Autonomy mean?

The battery duration at a specified load level is referred to as the battery “autonomy”. A UPS battery can be sized to support loads from a few minutes up to several hours, however the cost of a large battery at a high load level can sometimes mean that a Diesel Generator should be considered. Increasing the ‘autonomy’ is achieved by adding extra battery strings connected in parallel, however it is important that the charging capability of the UPS system is considered.
