If you can't determine which of the two cables connected to your solar inverter is the AC output then try the following steps:
- Check your solar installation manuals
- Search online for your inverter make and model
- Talk to your solar installer or electrician
If you have tried the above steps and are still unsure which cable to attach your sensor to, then take some clear photos of your inverter showing the cables and contact your Powersensor retailer for help.
