Good day everyone.
I am struggling to set up my assistants on my 8kVA quattro, and was hoping that someone could help.
Need: To reduce the time that AC2 takes to reconnect after mains fails/gen starts and assumed load and Gen/Mains returns.
For instance, when mains is lost AC2 is turned off, and only after the generator is running for a minute and a bit does it get turned back on. I know this is to allow the generator to start up and get to speed, but it does the exact same thing when mains returns. For instance, when mains returns it first turns off AC2 transfers the load from the gen to the inverter then to mains, and then again after a minute or so AC2 is turned back on.
This time is too long for me. Ideally, I would like it to be 30seconds or so form when the generator assumes the load and 10seconds when mains returns.
I have tried to use the Assistants (Programmable relay) to make this happen but the issue I am having is when mains returns and the gen is running. It doesn't turn off AC2.
Can anyone help or give me a simpler solution on how to implement this. I have tried now a few combinations of assistants which have not worked for me, I will put images of my attempts.
On a side note, I feel like this should be a setting in an update, a simple time-based setting which users can adjust to change how long it takes.
Assistant set 1:
The result of this assistant set was:
1. When mains failed (ACin1) and the generator (ACin2) wasnt running ACout 2 was turned off.
2. The generator (ACin2) turned on (triggered by the Venus).
3. Roughly 30 seconds later ACout 2 was then turned on.
4. When mains returned, the system was overloaded as ACout2 was not turned off during the change over.
Assistant set 2:
The result of this assistant set was:
1. When mains failed (ACin1) and the generator (ACin2) wasnt running ACout 2 was turned off.
2. The generator (ACin2) turned on (triggered by the Venus).
3. Roughly 30 seconds later ACout 2 was then turned on. (so far all going perfectly)
4. When mains returned and the unit attempted to do the changeover, but it was noted that ACout2 as still on, hence it would have overloaded if more appliances were running.
Assistant set 3:
The result of this assistant set was:
1. When mains failed (ACin1) and the generator (ACin2) wasnt running ACout 2 was turned off.
2. The generator (ACin2) turned on (triggered by the Venus).
3. Roughly 30 seconds later ACout 2 was then turned on. (so far all going perfectly)
4. When mains returned and the unit attempted to do the changeover, but it was noted that ACout2 as still on, hence it would have overloaded if more appliances were running.This was exactly the same as the previous assistant set.
5. It was noted that if the gen was not running, and mains restored then ACout2 would engage 30 seconds after it is present. So as it stands I am having issues with ACout2 turning off during the change back scenario, where ACin1 and ACin2 are present together.
