Generator shuts down; controller shows E24 Neutral Current High / Unbalanced Load.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Severely unbalanced single‑phase loads, Neutral‑earth fault, Incorrect CT wiring, Faulty load distribution

Safety first: Isolate generator from load before opening panels.

Review load distribution: Check how single‑phase loads are spread across phases. Rebalance loads to minimize neutral current.
Inspect neutral conductor: Ensure neutral cable is correctly sized and connections are tight.
Check for neutral‑earth faults: Use an insulation tester to detect unintended neutral‑earth connections downstream.
Verify CT wiring: Confirm neutral CT (if used) is correctly installed and wired to the Aksa controller.
