Recommended Cable Specifications
These specifications are a general guide, actual wire sizes and ratings should be verified based on use, load calculations, and local electrical codes.
Description | Terminal ID | Cable Type | Notes |
|---|---|---|---|
Ground |  | Bare or Insulated Copper | Connect to a ground rod or Ufer ground-in pad for low-resistance grounding. |
Communication Cables | LYNK II - RJ45 for Ethernet and CAN-based connections. | Standard CAT6 or higher Ethernet Cable | Run two separate cables: One dedicated for CAN bus communication with the inverter and another for the internet connection to the LYNK II Gateway. |
AC Auxiliary Connection | J6 (Pre-Wired Connector) | Use cable rated for wet and dry. | Continuous current less than 20 A, circuit breaker 32 A, use #10 AWG copper minimum, as per NEC guidelines for ampacity. Adjust for longer runs or higher temperatures. |
DC Connections | DC Distribution Fuse Terminals (4 Positive, 4 Negative). 70 A Standard. | A high-strand, flexible single-conductor cable insulated with XLPE, RHW-2, USE-2, PV Wire, or equivalent, is used for high-voltage DC applications (750 Vdc). | Check the PCS or inverter manual for recommended or maximum wire size. |
