Victron (#TeamBlue) Advanced Systems + VRM - How We Done It -

[Samro]

Hello! thank you for sharing this, I have put it to good use.
One question I have is about the “quiet hours” feature. I am quite possibly being thick but I can’t follow the inverse logic of the “normally closed” operation of this feature. What would the quiet hours setting need to be to achieve what you suggest in your post?

The quiet hours feature isn't relevant unless you want to set a different cut off threshold during the day/night.
My settings are:
Quiet hours off:


With "Quiet hours" set to "off", the settings for "Quiet hours" are ignored by the system. Only the Start & Stop settings are used by the system.


The selection of "normally closed" windows ll depend on the wiring ports used on the Cerbo.

Cheers for the response. My question more specifically is how can the “quiet hours” be configured when the “generator stopped” status is the setting for the (NC) relay to activate the water heater?

i.e. “quiet hours” stops (or limits) generator start up, but generator running is the NC “relay open” (heater off) setting.

My brain is scrambled trying to figure this out.

I tried setting the “quiet hours” to be 0700hrs-15:00hrs (to allow afternoon solar input to recharge the battery), but this didn’t appear to have the desired effect.

Have you turned on Auto Start function in the Generator Start/Stop settings of the Remote Console?

Yes Auto Start is on, but isn’t that related to the SOC “condition”? I’ll keep fiddling about with the “quiet hours” settings to see if I can make it work.

Like I said I’m struggling with the inverse logic (generator stop means heater is on and vice versa).

 

[Samro]

Quiet hours simply allows a second set of parameters to be set.
So for example
You could set the threshold to a lower level of SOC, before disconnecting the load during the "quiet period". (The times of the quiet period are input once the option is enabled.)

Yes Auto Start is on, but isn’t that related to the SOC “condition”?

Yes. That is what you are wanting to achieve isn't it? You want to disconnect a load at a given threshold and reconnect at a higher threshold. This can be SOC or Battery Voltage for what we want to achieve. Although SOC will work better for Lithium due to flat charge curve.

"Auto-start" function needs to be enabled to allow the conditions in the "Generator Start/Stop - Conditions" to trigger the relay. Likewise, "Quiet Hours" function needs to be enabled in the "Generator Start/Stop - Conditions" for the Quiet hours condition ti trigger the relay.

Ref the inverse logic - Remember that when the Genset is On, the batteries charge. All you are doing is using the trigger to turn off a load to prevent it from overtaking the charge being delivered via Solar/DC-DC charging devices.

So, if "Genset on" then the load driven by the relay is off.

Cerbo GX WiFi - had my first drive to work today and when I got back my Cerbo GX - connected to my home WiFi the last few days - didn't want to connect to any WiFi. Just gave an error. I turned off the WiFi hotspot and it then it let me manually connect a few minutes later.

Maybe something to do with the heat? It has been very hot in the van the last couple of days.

Can the Cerbo GX prioritise WiFi connections? IE if I have a 4g hotspot in the van but it's parked up outside my house with access to my home WiFi, can I get it to prioritise my home WiFi signal over the 4g WiFi signal in order to save data?
