There are a few reasons that the solar readings in the app can appear incorrectly. Among them are the following:
- Installation issue: The solar sensors are not placed on the A/C side of the incoming solar feed. Sense monitors A/C (alternating current) power only and not D/C (direct current) power.
- Installation issue: The two solar sensors are not placed in a matching direction which is causing the polarities to be opposite of each other. The readings essentially cancel each other out. The app will indicate this by showing one solar wattage reading as negative and the other as a positive value. Flip one or both sensors so they match in orientation.
- Installation issue: The solar sensors are not plugged in or placed around the incoming solar feed. In most scenarios, the solar should feed into a breaker at the panel or can tap into the main service leads. Verify that the solar sensors are plugged into the middle port on the monitor (between power cable and main sensor port) and are placed around each leg of the incoming solar feed.
- Inverter issue: The solar inverter may not be powered up or it may not be commissioned just yet. If permitted, reboot the solar inverter and verify that it powers on as expected.
