On a venus GX , Is there a way to change relay state according MPPT or battery voltage ?
If possible, how to proceed ?
Thank you for your answer.
I found this : https://www.victronenergy.com/live/ccgx:generator_start_stop
Will test the proccess on site this weekend.
On site I plugged a led + resistor under 12V on Relay 1, I'm able to turn it on/off only by using generator manual start/stop from the main menu. However, no success using battery voltage, relay 1 do not change state while condition under setting are setup to battery voltage, under 24V the Relay should Switch but not. Any ideas ?
I have been 'away' sailing in the Sth Pacific for the last seven months and am now looking to 'resolve' this relay issue to use for heating water (Energy dump).
I have reviewed the latest manual version and nothing appears to have changed in this regard over the last six months (i.e. since Jan 2019). If this is correct I still come up against the 'wall' of how to have the logic domain (VenusGX-Relay using Gen/Start stop) moving high (+ve) when the following 'voltage' condition is met.
To be specific. When the Victron Lithium battery bank voltage as read by the battery monitor (Lynx in my case) is higher than say, 27.1 V (25-28.4 I guess) then I want the relay ON. When the voltage drops to below, say 26.3 VDC, then I want the relay to go open (off) and hence stop heating the water.
There is no apparent, to me, logic for this as it is the 'opposite' logic to when you want a generator to start and stop.
If I understand your comment above I can 'reverse' the physical world (i.e. relay hi/low reversed to lo/hi using other means but it is the 'logical' trigger which is missing and the variable parameter associated with this (i.e. the threshold voltage in my case).
Are you able to provide me with the 'dummies' guide so that I can see where I have not been able to get my grey matter focussed?
