BATTERIES AND CONFIGURATIONS

The POWER+ is flexible in structure, in that it may be extended by adding modules as required.
The battery bank is common to all modules and may comprise one or more branches to include
a redundant battery if desired.
For systems from 10kVA through 30kVA, the batteries may be internal; otherwise, the batteries
are housed in external cabinets. See Figure 6-3 on page 68 for details on battery cabinet wiring
and connections.
6.1.1

INTERNAL BATTERIES

Up to 3 internal packs, each containing 64 × 12v/5Ah batteries, may be housed in the Power+
system cabinet. This would provide 4 minutes of backup time at full load, on a redundant
system of 5 modules (total 40kVA). See Figure 6-1 below.
Each battery pack is 6U high and weighs about 135 kg on average, depending on the
manufacturer and model. It comprises 4 drawers, each containing 16 batteries, to facilitate
removal and replacement. See Figure 6-2 on page 67.
