Pollution Degree 2; -30°C to +60°C operating ambient temp.; 15-95% non-condensing humidity; max. altitude 2000 m; outdoor use; Type 3R enclosure.

1. Mount the PVS6

1. Select an installation location that is not in direct sunlight.
2. Mount the PVS6 bracket to the wall using appropriate hardware for the mounting surface that can support at least 6.8 kg (15 lbs).
3. Fit the PVS6 onto the bracket until the mounting holes at the bottom are aligned.
4. Use a screwdriver to secure the PVS6 to the bracket using the provided screws. Do not overtighten.

2. Wire the PVS6 Power

DANGER! Hazardous voltages! Do not power up the system until after you complete Sections 1 through 3. Accessing the system involves possible contact with potentially lethal voltages and currents. No attempt to access, install, adjust, repair, or test the system should be made by anyone who is not qualified to work on such equipment. Use copper conductors only, with a minimum 75°C temperature rating.

1. Use a screwdriver (do not use power tools) to prepare the PVS6 for AC wiring:
   • Using a flat-blade screwdriver, carefully bend the PVS6 cover retention tab back to release and then remove the outer cover.
   • Remove the lower AC wiring cover.
   • Remove the upper AC wiring cover.
2. Run power conduit from the service panel to the PVS6. If you use the rear conduit entrances, seal the holes on the bottom of the enclosure with the included hole plugs. Use a step drill if you are using rear or center bottom entrances.
3. Connect the PVS6 to either a 15 A (with 14 AWG) or a 20 A (with 12 AWG) UL Listed dedicated dual-pole breaker. Note: For AC modules, this breaker should be in the same service panel containing the AC module output circuits.
4. Strip wires to 12 mm and land according to the color-coded labels (black wire to L1, red wire to L2, the white wire to N, and green wire to GND) in the J2 terminals on the bottom left of the PVS6 board, and then close each locking lever completely.

3. Install and Wire the Consumption CTs

DANGER! Hazardous voltages! Do not power up the system until after you complete Sections 1 through 3. Accessing the system involves possible contact with potentially lethal voltages and currents. No attempt to access, install, adjust, repair, or test the system should be made by anyone who is not qualified to work on such equipment.

1. Maximum 120/240 VAC split phase, three-wire system, Measurement Category III, 0.333 VAC from a current sensor rated to measure a maximum of 50 A.
2. The SunPower-provided CTS are suitable for use on 200 A conductors. CTs may be labeled "100 A" but this is a calibration reference rating only. You may install CTs in parallel or bundled configurations. Refer to the *Consumption Meter CT Installation Instructions*.
3. Turn off all power to the main service panel in which you are installing CTs.
4. Place the CTs in the main service panel, around incoming service conductors, with the side labeled "THIS SIDE TOWARD SOURCE" positioned towards the utility meter and away from the loads. Never install CTs in the utility-designated section of the service panel.
5. Place the L1 CT (black and white wires) around the incoming Line 1 service conductor.
6. Place the L2 CT (red and white wires) around the incoming Line 2 service conductor.
7. Align the steel core pieces and snap the CTs closed.
8. Route CT wires through conduit to PVS6.
   • Running CT wires: You may run CT and AC wiring in the same conduit. Do not run CT wiring and internet communication cables in the same conduit.
   • Extending CT leads: Use Class 1 (600 V rated minimum, 16 AWG maximum) twisted-pair instrument cable and appropriate connectors. SunPower recommends the use of silicone-filled insulation displacement connectors (IDC) or telecom crimps; do not use power cables (for example, THWN or Romex) to extend the CT leads.

4. Verify CT Voltage Phases

1. Turn on power to the PVS6.
2. Use a voltmeter to measure voltage between the PVS6 L1 terminal and the L1 incoming service conductor in the main service panel with the L1 CT in place.
3. If the voltmeter reads:
   • 0 V: The phases are correctly aligned.
   • 240 V: The phases are incorrectly aligned. Move the CT to the other incoming service conductor and retest to verify 0 V.
4. Repeat Steps 4.2 and 4.3 for L2.

5. Connect System Communication

1. Replace the upper AC wiring cover.
2. Replace the lower AC wiring cover over the AC power wires (on the left if you ran through the left hole; on the right if you ran through the right hole).
3. Run communication conduit to the PVS6 conduit opening if required. If you use the rear conduit entrances, seal the holes on the bottom of the enclosure with the included hole plugs.
   • Warning! Never run inverter communications cable in the same conduit as AC wiring.
4. Connect communication for each device using the corresponding port:
   • AC modules: Verify that you connected the AC modules to the AC module subpanel. No additional connection is required; the PVS6 communicates with AC Modules using PLC protocol.
   • SMA US-22 inverter: Connect an RS-485 communication cable from the PVS6 RS-485 2-WIRE port (blue) to the first (or only) inverter in the daisy chain. Follow the manufacturer's instructions to daisy-chain additional SMA US-22 inverters.
   • SMA US-40 inverter: Connect a tested Ethernet cable from the PVS6 LAN1 port to the first (or only) SMA US-40 port A or B. Follow the manufacturer's instructions to daisy-chain additional SMA US-40 inverters using Ethernet cables.

6. Connect the PVS6 to the Internet

Connect to the customer's internet using either:

• Ethernet cable: from PVS6 LAN2 to the customer's router (recommended method).
• Customer's WiFi network: connect during commissioning using the customer's WiFi network name and password.

7. Commission with the PVS Management App

1. Turn laptop WiFi off.
2. Use an Ethernet cable to connect your laptop to either the PVS6 or the inverter based on installation type:
   • AC module or SMA US-22: Connect laptop to PVS6 LAN 1 port.
   • SMA US-40 inverter: Connect laptop to the available communication port (A or B) in the last (only) inverter.
3. Open a browser (the latest version of either Chrome or Firefox) and type: www.sunpowerconside.com.
4. Follow the PVS Management App onscreen instructions.
5. Replace the PVS6 enclosure cover by snapping it into place.

If the equipment is used in a manner not specified by SunPower, the protection provided by the equipment may be impaired.

• WARNING! To reduce the risk of electric shock, always open or disconnect the circuit from the power distribution system (or service) of the building before installing or servicing current transformers (CTs).
• The CTs may not be installed in equipment where they exceed 75% of the wiring space of any cross-sectional area within the equipment.
• Restrict installation of CTs in an area where it would block ventilation openings.
• Restrict installation of CTs in an area of breaker arc venting.
• Not suitable for Class 2 wiring methods.
• Not intended for connection to Class 2 equipment.
• Secure CTs and route conductors so that they do not directly contact live terminals or bus.
