CerboGX Generator Start/Stop Time band

Is it possible to have this function only run in a particular time period? For instance between 10:00hrs and 15:00hrs.

I've two contactors which I wish to control on NO/NC based on state of charge. For instance using the CerboGX start/stop I can stop when SOC >98% and start when SOC<95%. In reality its an inverse operation in that by Stoping I am actually energising one contactor and by starting I am energising another.

I noticed there are some quiet hours settings which I have tried to use with the time period but with no such luck. Can quiet house stop the logic from functioning? For instance set to 15:00hrs to 10:00hrs?

I know this function was designed to start/stop a genset but I wish to use it to control an external circuit. Much appreciated if some one knows how to time bind this function. @mvader (Victron Energy) any ideas?

Hi, I'm not sure what is possible in all corner cases with the normal generator start stop function; you'll have to try.


What I do know is for other types switching, Venus OS Large will give you (sort of) unlimited flexibility: https://www.victronenergy.com/live/venus-os:large

Interesting. But what really was the intention of Quiet Hours? I have read that you could set lower triggers so that Quiet hours become when necessary runtime. So does the tech ignore Quiet Hours?

Downloading the Venus Large. The read on it sounds very very interesting. Will try it out and report back
