Description
This is a request for Quotes for battery backup equipment. The Naval Research Laboratory requires four (4) Emergency Battery Backups, each meeting the following specifications:

5000 watts of Single-phase power with a 4.8 KWH battery bank
120VAC Input/120VAC Output
(6) 20A breakers.
Input conductor size 6 AWG, output conductor size 12 AWG
Surge wattage 10,000

Please submit quotes to the points of contact listed in this announcement prior to the deadline.
In response to numerous vendor questions the deadline for quote submissions has been extended. Q&A with vendors is provided below:

Runtime Expectation - Is there a minimum required runtime (in minutes/hours) at the 5,000 W load? This is load dependant. This configuration of batteries has a 4.8kWh capacity, so given a 50A breaker at 120VAC = 6000w, at maximum draw that would be 0.8 hrs, but typically the unit is expected to last a minimum of 4 hrs. The capability of integrated battery expansion is also a feature necessary to this unit, so this runtime number could be expanded by 3X by adding a battery module chassis.

Breakers - Should the six (6) 20A breakers be integrated into the UPS chassis, or may they be provided via a separate distribution panel? Yes, the (6) breakers are an integral aspect of the UPS chassis.

Scope - Please confirm this is a procurement-only requirement (equipment delivery only), with no installation or commissioning expected. Equipment delivery only

Certifications - Are there any specific standards required (e.g., UL, NFPA, MIL-STD, TAA compliance)? At minimum, Inverter: UL 1741, Battery: UL 94V-0

Provide a specification for the battery equipment Battery Backup, Output capacity: 5k, Battery Capacity: 4.8 kWh @ 48V, Hardwired, Power requirements: 50A, 120 VAC 60 Hz single phase or 240 VAC, Output: six(6) 120 VAC 60 Hz, 20A single phase integrated breakers, Waveform: Pure Sine Wave performance, Tr...
