This amendment is issued to post the job walk sign in sheet, updated Statement of Work, and PV array description and layout.

All other terms and conditions remain unchamged.

STATEMENT OF WORK

1. Contracting Officer’s Representative (COR).

2. Contract Title. SATCON Photovoltaic (PV) Inverter PMI Service

3. Background. Provide Annual and Semi-Annual PMI Service on three (3) PV inverters and associated major distribution components. System was installed in 2012 and has not had any services since installation.

4. Basic Requirements.

a. Contractor shall provide PMI and other service work to include major distribution components of three (3) photovoltaic (PV) generating plants at VA Long Beach Healthcare System (VALBHS), 5901 Bellflower Blvd, Long Beach, CA 90804. Provide a summary report of all results and findings of which will be used to establish the maintenance baseline. Major distribution components of each plant includes: Satcon Inverter, 480VAC Safety Fusible Disconnect switch, 120VDC Safety Disconnect switch. Location and size of PV inverters are:

(1) Bldg-149 – 75KVA 3-phase Satcon Inverter, Mdl # PVS-75 (exterior unit), Main DC safety disconnect switch, Main AC safety disconnect switch.

(2) Bldg-50 – 50 KVA 3-phase Satcon Inverter, Mdl # P VS-50 (interior unit), Main DC safety disconnect switch, Main AC safety disconnect switch.

(3) Bldg-150 – 50 KVA 3-Phase Satcon Inverter, Mdl # PVS-50 (interior unit), Main DC safety disconnect switch, Main AC safety disconnect switch.

b. All three (3) invertors shall receive PM in strict accordance with the Satcon Installation, Operation and Maintenance Guide, publication # PM00450 – Revision 1. The Preventative maintenance will include both annual and semi- annual requirements identified in the manual. PMI will include all items identified in the manual, and shall be in strict accordance with the manual.

c. Contractor shall provide all tools, materials, and all other services required to perform this PMI.

(1) Meter(s) shall have calibration certificate of not more that 1-year earlier than this PMI.

(2) All replacement materials shall be new.

(3) All work shall be conducted during normal business hours, form 8:00am until 5:00pm.

5. Specific Tasks - PMI Service:

Semi-annual PMI requirements: Perform the following for all major distribution components, as a minimum:

a. Cleaning, Inspection and Cables: Cleaning and inspection of inverter interior. Clean with compressed air. Inspect cables and connectors for damage.

b. Power Components: Clean, inspect and torque all terminals. Inspect power conductors for damage. Inspect door hinges lubricate with 3M or equal silicon spray lubricant.

c. Due to thermal expansion and vibration, all clamps, power bolt-on connections, logic screw-on connections and rectifier diode/insulated gate bipolar transistor (IGBT) mounting shall be re-torqued per manufacture specifications.

d. Fans / Blower and Air Filter Maintenance: Verify proper operation of fans/blower and air filter. Replace all air filters with new filters where replaceable. Filters that are cleanable/re-usable, shall be thoroughly cleaned. Clean all fan impellers. Ensure fans are free from noise or binding.

e. Printed circuit boards shall be cleaned and shall be free of dirt and foreign materials.

f. Perform temperature checks on all breakers, connections and associated controls (look for discoloration).

g. Perform a complete visual inspection of the equipment including subassemblies, wiring harnesses, contacts and major components and record ambient operating temperature and deliver with PMI report.

h. Check inverter modules for the following:

(1) IGBT’s and inverter boards for discoloration

(2) Power capacitors for signs of damage

i. Record all voltage and current readings via the front display panel and include in maintenance report.

j. Measure and record all low voltage power supply levels and include results in maintenance report.

k. Ensure cleanliness of the cabinet, ventilation system and insulated surfaces.

l. Check for corrosion on all terminals and cables.

m. Torque terminals, connectors and bolts.

n. Check all fuses for open or signs of excessive heating (inverter & combiner), record temperature and condition in the maintenance report.

o. Check the condition of both the AC and DC surge Suppressors.

p. Check the operation of all safety devices (E-stop, Door Switches GFCI)

q. Replace all Air Filters and clean associated elements.

r. Include in maintenance report all deficiencies encountered.

s. Attach an updated maintenance schedule onto a conspicuous location on inverter case. The schedule shall be protected against exterior elements (rain and UV sunlight).

Annual PMI requirements: In addition to all items in the Semi-Annual PMI service, also perform the following for all major distribution components, as a minimum:

a. Check all nuts, bolts, screws and connectors for tightness and heat discoloration.

b. Calibrate all electronic subsystems to system specifications. Provide calibration record in maintenance report.

c. Do not install software upgrades or updates.

d. Measure and record phase to phase input voltages and currents and record in maintenance report. Compare with Inverter display to ensure inverter accuracy of inverter metering within manufacture tolerances. Include percent error in maintenance report.

e. Perform a thorough cleaning of the inverter case exterior and the associated safety disconnect switches.

Additional Service Requirements:

a. As a part of the Bldg-149 75KV PMI inverter service, replace defective display, display board, ribbon cables, connectors and wiring such that display is fully functional, with brightness adjusted such that the display can be read during the middle of a sunny summer day, without being washed-out by the sun.

b. At all three inverter systems, service the disconnect systems. However, it must be noted that the Utility AC power is derived from bus tap at the distribution board. In as much, the lugs of safety switches of which land Utility AC power shall not be serviced as full building shut down would be required – however they shall be scanned for hot spots and findings reported. Safety switch service shall include:

c. Removing all dust and debris with compressed air or vacuum.

d. Inspecting terminal for signs of excessive heat (looking for discoloration).

e. Torqueing of terminals.

f. Immediately after contract is awarded, provide a quantity of (2) keys per inverter to the COR.

g. Contractor will coordinate with COR no less than 24 hours prior to any work related to this contract.

h. Contractor will provide ladder and implement appropriate safety measures when working on system at bldg. 50.

Photovoltaic Cleaning and Wiring Checks:

a. All photovoltaic panels on each roof shall be cleaned with non-abrasive means with Deionized water to prevent water stains.

b. Photovoltaic conductors shall receive visual inspection for failing or brittle insulation, hot spots. Terminations, splices and bolted connectors shall be inspected with verification that hot spots or loose nuts, bolts and screws do not exist.

Maintenance Report: Shall be prepared in a professional manner.

a. Submit maintenance report for all three systems in a small 3-ring binder. Cover and spline shall be prominently posed with PMI title, date and contractor name and phone number and name of any subcontractors with contact information.

b. Interior shall have table of content and dividers for each of the three PV inverter systems.

c. Each divided section shall have its maintenance report, well organized and typewritten.
