Victron Phoenix 500VA 24-Volt - voltage unsteady/shutdown

Is it normal to see voltage swings on a 250W load for the Victron 24V 500VA inverter? its been swinging from 113v -125v and shuts off the inverter every 20 seconds or so. On the same load, my multiplus is holding 120V exactly.

Battery is at ~26V with lots of AH left (the multiplus can run full blast).

It is on the latest firmware and is connected to a Cerbo GX, 30A fuse, 8Gauge pure copper wire, connections are secure.

Any help is appreciated , otherwise its going back, its brand new from Victron dealer.

What is the load? if its inrush is approaching 900W then the inverter may be trying to start it multiple times before giving up.

The additional capacity of the multi may explain the discrepancy!
