4.3 Test String Output Voltage of PVG
• PVG default state from factory is OFF
• Safety voltages (OFF) when PV-1 port is powered by a PV module
PVG_1: 0.65 Vdc
PVG_2: 1.4 Vdc
PVG_3: 1.8 Vdc
4.4 Connect Homeruns
● PVGs must be connected to PV modules before connecting homeruns
● Following steps are recommended* to reduce cross interference between PLC signals from different
PVG controllers
● Separate raceway of homeruns for different PVG controllers as far as possible
● Keep positive and negative conductors of homeruns of the same PV string as close as possible to a
twisted pair in a cable tray
● Avoid conductors of homeruns for different PVG controllers in the same raceway
● Separate conductors for different PVG controllers as far as possible
* PVG and PVG controllers use advanced signaling to eliminate cross talk interference between adjacent systems
