AC Ignore with assistants but also switch the programmable relay

Q&A and troubleshooting

Hi all,

Would it be possible to also switch the programmable relay when using assistants to enable ac_ignore?

I understand that the general flag must be used to enable ignore ac, but then the programmable relay is not switched also?

I would like to enable ac_ignore with assistants and also switch the programmable relay on the ac_ignore condition, is this possible?

Thanks!

To ignore the AC IN you select the “general flag” as the “relay” in the “programmable relay” assistant.

So you can still use the real “primary programmable relay” (or K1 or K2 or AC OUT 2) for something else.

Thanks Matthias,

I understand your explanation and this is the way i intend to set ac_ignore with assistants but…

If i set the “general flag” as the “relay” to use ac_ignore then ac_ignore works but how do i then make an actual relay (primary programmabe relay) also switch on ac_ignore?

Thanks!

So to reply to my own thread for a proposed solution, but not sure if this will work…

So i set ac ignore with the ‘general flag’ assistant.

And then make 2 more assistants (one for ‘on’ and one for ‘off’) for the aux relay that have exactly the same conditions as my ac ignore conditions.

Is this the right way to make a relay follow ac ignore condidtions using assistants?

Would this result in the relay switching at exactly the same time as ac ignore switches?

thanks!

So what i would like to achieve with the image below is:

  • ignore ac in
  • switch the primary programmable relay on the same conditions as ignore ac in (this is needed to shut down my solar inverter, i don’t want to inject into the grid)

Can someone comment on this? thanks!

I think this should work, can anyone comment on this?

Are the conditions within one assistant OR’ed or AND’d ?

Thanks

AND… Both must be true to trigger

On is always priority over off. So if any on is triggered the offs will be ignored even if conditions are met.

What i have found easier to get right is use an aux or temp input to set the open and close of the primary relay and (wire it to) use the GX relay (assigned as a generator start stop) then put all the load and soc conditions in there.

I guess that is if you aren’t using it to start an actual generator :upside_down_face:
