Reactive power of HMS-450-1T not shown correct „VoltVar“ is activated #2091

What happened?

Ich activated the „VoltVar“ / „VV“ Feature in the Grid Profile and now the Webinterface shows straValues for the „Blindleistung“. I have also HMS-2000-4t installed there it seems not to work (no Blindleistung is shown).

To Reproduce Bug

Activate the VoltVar in the Grid Profile and increase the voltage that the Production of reactive power is started.

Expected Behavior

The values that are shown are correct.

Install Method

Pre-Compiled binary from GitHub

What git-hash/version of OpenDTU?

24.6.10

This behavior is maybe triggered because of the reason that the reactive power is a function of the voltage Q(u) and ther te reactive power could be negative if voltage is relatively low…
