Battery Sizing Basics
For multi-string battery plants, the trend is to provide a disconnect circuit breaker for each battery string, rather than using a common breaker for the entire battery bank. Individual circuit breakers help isolate the faulty string, allowing maintenance personnel to take out one battery string at a time.

Battery configuration choices to optimise UPS reliability
Note that a single string of larger batteries is usually cheaper than multiple strings of smaller batteries. If a multi module parallel UPS power supply is configured with a single battery string per module, a mains failure will immediately threaten the system''s ability to support the critical load. The severity of the threat is higher for ...
