All single-phase hybrid inverters and AC chargers (H1-G2 and K Series) are supplied with a CT clamp & cable as standard (this is an optional add-on for F & S Series inverters).
The cable supplied is 10m in length and we permit an extension up to a maximum of 30m. You can use 2-core RS485 cable, but most commonly, installers will opt for CAT5/6 with twisted pairs. The cable can also be shortened if you have a very short distance from the incoming supply to the inverter.
For full CT installation and troubleshooting, see this article.
