MultiPlus 48/3000/35 overload and high temperature?

We are testing a 3 phase offline MultiPlus 48/3000/35 system.

Issue: With a 3 * 2800 W load (heater - power factor ~ 1) we see overload and high temperature alarms? The system also eventually shuts down?

Conditions:
- Room temperature: 21 C
- Grid: Off
- PV: Off



Best regards,
Lars Lindegaard Mikkelsen

The Multiplus 3000 is indeed overloaded because max RMS power is 2400W.
