No feed-in, AC Input current fluctuates wildly — Normal operation due to X-capacitors

What does No feed-in, AC Input current fluctuates wildly mean?

The AC input current may appear to fluctuate significantly, even becoming negative, when the system is in optimize mode with no feed-in. This is normal and caused by the X-capacitors in the Multi.

• Normal operation of the Multi/Quattro's internal X-capacitors.
• System is operating near 0W real power.

Click steps to track your progress.

1. 1

   Observe the 'Input power' readings instead of the AC input current for a more reliable indication of power flow.

2. 2

   Confirm that the system's optimization mode is correctly configured.

3. 3

   Ensure the firmware of all system components is up to date.
