Input voltage requirements

When you plan for the power requirements of the storage system, consider the input voltage requirements.

The following table provides the input voltages and frequencies that the storage system supports.

Table 1. Single-phase input voltages and frequencies
Characteristic Voltage (single-phase)
Nominal input voltages 200-240 RMS V AC
Minimum tolerated input voltage 180 RMS V AC
Maximum tolerated input voltage 256 RMS V AC
System maximum current rating DS8886 40 Amps
DS8884 24 Amps
Wall breaker rating (1 ph)1 DS8886 US, Canada, and regions that require 20% derating factor 50 - 63 Amps
DS8886 Geos with no derating requirement 40 - 63 Amps
DS8884 All regions 30 - 63 Amps
Steady-state input frequencies 50 ± 3 or 60 ± 3.0 Hz
PLD input frequencies (<10 seconds) 50 ± 3 or 60 ± 3.0 Hz
  1. Regions such as the United States and Canada require 20% derating for power distribution circuits. For these regions, a minimum 50 A circuit breaker is required for a 40 Amp rated system such as the DS8886. Verification of applicable local standards is required for system installation. Some configuration restrictions to limit power consumption can allow reduced breaker ratings on a regional basis.
Table 2. Three-phase input voltages and frequencies
Characteristic Three-phase delta (3ØΔ) Three-phase wye (3ØY: LL[Line-to-Line])
Nominal input voltages 200, 208, 220, or 240 RMS V AC 380, 400, or 415 RMS V AC
Minimum tolerated input voltage 180 RMS V AC 315 RMS V AC
Maximum tolerated input voltage 256 RMS V AC 456 RMS V AC
System maximum current rating

Wall breaker rating (3 ph)1 30 - 60 Amps 20 - 32 Amps
Steady-state input frequencies 50 ± 3 or 60 ± 3.0 Hz 50 ± 3 or 60 ± 3.0 Hz
