6 FAQs about [One battery has several strings of power supply]

Can a ups have multiple Battery strings in a parallel configuration?

Equipping a UPS with multiple battery strings in parallel configuration can dramatically reduce the risk of battery failure, which is one of the leading causes of load loss.

How many parallel strings can a battery have?

The absence of any theoretical limitation to the number of parallel strings is borne out by the experience of telecom operators, and at least one battery manufacturer allows up to 16 parallel strings, depending on system voltage.3

How many batteries do you need for a ups?

A typical configuration could have three serial strings, each with twelve 32 12V 40AH batteries, providing the UPS power supply with 384V and a 120Ah capacity. The extra batteries cost more than the single string, but provide longer battery autonomy during a mains failure.

Are parallel Battery strings worth it?

Multiple, parallel battery strings can solve this but are more expensive. Users can tune their battery string configuration and interconnection with parallel UPS modules to achieve the best cost/redundancy trade-off for their particular needs. A ‘single’ or ‘serial’ string has identical battery blocks wired in series.

Should a stationary battery be connected parallel?

However, for most of today’s stationary batteries it is better to make parallel connections at the string level. One suggestion is to limit the number of strings in accordance with the system voltage, allowing more parallel strings at lower voltages.
