Copyright 2022 SunPower Corporation PVS6 Installation Instructions and Quick Start Guide 531566 RevD 2 of 2 Technical Notification Title Identifying New PVS6 Ethernet Connection Ports, 650368 Date July 21, 2022 Applications Engineering Team Authors Application SunPower Equinox and SunPower SunVault Storage installations Overview The SunPower PVS6 monitoring device now utilizes a plug-in dongle port for Ethernet connection. The PVS6 with the dongle port is part number 60232 and has a W in its serial number (for example, ZT214385000549Wxxxx). The traditional PVS6 without the dongle port is part number 529027 and has an A in its serial number (for example, ZT214385001823Axxxx). This Tech Note describes how to install each of these. Note: During the commissioning process, SunPower Pro Connect will automatically assess the PVS6 serial number and will provide a popup message alerting you if your PVS6 lacks the traditional Ethernet ports. Identifying Which Variant You Have View the serial number on the PVS6:

If it contains an A (for example, ZT214385001823Axxxx), the Ethernet ports are still present and may still be used for commissioning. No dongle is required. If it contains a W (for example, ZT214385000549Wxxxx) the Ethernet ports are not present, meaning that for commissioning you must use a dongle. PVS6 units with an A in their serial number will likely look familiar because all the standard ports are present:

If the PVS6 is on, turn it off, plug in the appropriate dongle, and then turn the PVS6 back on. If your PVS6 has the Ethernet ports (if it has an A in its serial number), and the WiFi signal is strong, you may commission via WiFi, which does not require a dongle. If your PVS6 lacks the Ethernet ports (if it has a W in its serial number), you must first assess the existing site equipment to determine dongle applicability. If the site only has an Equinox system:

For a PVS6 that has a W in its serial number, and no SunVault system is present, no dongle will be present from the factory:

If the WiFi signal is strong you may commission via WiFi (as you normally would when you have a strong signal). If the WiFi signal is weak, you must use an Ethernet cable:

1. Plug the USB end of a dongle into Port 3 (WAN/LAN2) on the PVS6. 2. Plug an Ethernet cable into the other end of the dongle. 3. Plug the other end of the Ethernet cable into the customers router. If the site has both an Equinox and a SunVault system:

In all SunVault installations the PVS6 is integrated into the Hub+ and one dongle will be preinstalled in Port 2 (LAN1) by the factory:

INDEPENDENT OF THE STRENGTH OR WEAKNESS OF THE WIFI SIGNAL:

1. Plug an Ethernet cable into the dongle thats connected to Port 2 (LAN1) on the PVS6. 2. Plug the other end of the Ethernet cable into the Ethernet port on the gateway in the BASE ESS enclosure. If the WiFi signal is weak:

1. Plug the USB end of a second dongle into Port 3 (WAN/LAN2) on the PVS6. 2. Plug an Ethernet cable into the other end of the dongle. 3. Plug the other end of the Ethernet cable into the customers router. Connecting the PVS6 If your PVS6 has the Ethernet ports (A in serial number), there are no changes to the instructions in the PVS6 Installation Quick Start Guide (QSG) 531566. You use this QSG to complete installation of an Equinox-only (standalone) PVS6 and commissioning of the Equinox system. SunPower Corporation proprietary information.
