In addition, the following briefly captures the technical details for major components of the installed power backup systems:

Inverter

  • Three units of 3.6 kW, 48VDC inverter/45 Amp Charger.
  • Outback inverters utilizing the FlexWare DC and AC boxes.
  • AC and DC circuit breakers as part off the Outback Flexware System
  • Equipment enclosure.
  • The surge protection adder
  • Additional kilowatt meters for the AC IN and AC OUT feeders.
  • Supplemental DC Smart charging for some sites.
  • An alarm system producing sound and light when the batteries are in need of charging, and before the low voltage disconnect takes over.

 

Battery

  • 48V battery bank of (a) 900 to 1,000 Ah or (b) 1200 to 1300 Ah or (c) 660 Ah
  • Batteries installed on welded metal racks, painted, with wood shelves and in secure locations.
  • Homerun battery cables - 2 sets of 4/0 (2-Positive and 2-Negative) along with paralleling cables of exact same length for complete circuit from the positive bus to the negative bus.
  • Deep Cycle batteries with maximum of 4 parallel strings and 50% depth of discharge.
  • Battery paralleling connections on a common bus bar.
  • Bidder will complete an initial full charge of the batteries, and assure that all of the batteries- water levels are topped off following this charge. Sufficient distilled water will be included in this proposal to be left with the operator to last for the first 6 months of operation.

 

Wiring

  • AC IN wiring in EMT conduit. AC OUT circuits cabled with 100% new and separate from any existing circuits. Also, the AC OUT circuits (with some exceptions) run in EMT conduit.
  • The new outlets and conduit feeding the outlets are identified differently from the main building circuits, by a different color paint and signage.
  • All wiring run in conduit and wire except for the battery cables.
  • All conduits are fastened to junction boxes, panel boards, circuit breakers, etc.
  • Grounding, conduit and wire installation in accordance with the 2008 National Electrical Code.
