MyPV AC-Thor in off-grid system - settings?

Hello,

the manual (https://www.victronenergy.com/live/actor_offgrid ) says that when using AC-Thor in an off-grid system frequency shifting (PV-inverter assistent) has to be activated at the Multi.

- Is this also necessary if only DC-coupled PV is used (no PV-inverter on AC-out)?

- what are the frequency settings in the "PV-inverter" assistent? Are the default-settings ok?


Best regards

Hi, in this system the PV assisant in the Multi will start control at 51 hz to 52 hz, but in the Ac thor it is written : 50.1 Hz (start) to 51 Hz (end). For me it does not sound logic but can you please confirm.

Hi @GregN

You either have to adjust the AC Thor settings to the Multi's, or adjust the Multi's setting to the AC-Thor settings.

Also: please check with local regulations if it's an on-grid installation.

Hi, yes,that assistant will control the ac-thor device through frequency shifting. Leave all the assistant settings on default

@ Lucian!

Is it right that the Multi can do the frequency shifting also if there is no AC-coupled PV (only DC-coupled PV)?

Does the Multi get the information for frequency shifting from the CCGX when surplus power is available at the MPPT?
