No feed-in, AC Input current fluctuates wildly

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

SolarEdge · ESS Systems

¿Qué significa No feed-in, AC Input current fluctuates wildly ?

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.

Causas comunes

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

  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.
