Volvo Load Management Calibration / Configuration Issue

Dynamic load management with the home energy meter appears inaccurate: charger reduces current too much or not enough, but no explicit error is shown.

Safety Warning

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

Incorrect CT orientation on home energy meter, Wrong main supply rating configured in Volvo charger, Miswired phases between meter and charger, Firmware bug in load algorithm

How to Fix / Troubleshooting

Safety first: Turn OFF power to the meter and charger before touching CTs or wiring.

Verify CT orientation: Ensure the arrows on the current transformers point toward the load as specified by the meter manufacturer.
Match phases: Confirm that L1, L2, and L3 at the meter correspond to the same phases at the charger.
Check configuration: In the Volvo app or installer interface, set the correct main breaker size and maximum allowable house load.

If behavior remains erratic after configuration checks, consult Volvo support for firmware updates or advanced diagnostics.
