I have my cerbo-gx connected to my quattro 15kVA through VE.Bus connection. I want to configure my quattro as “passthrough” configuration which can be specified in the “mode” list of the Inverter.Control node. The main goal is to allow bypass when certain external conditions are met without risking shortcircuit (for people asking, I still have a synchronoscope and other safety measures in hardware).
Nevertheless, I can’t access my Quattro inverter through the Inverter.Control. Actually, I can only see the device in “VE.BUS” node, which allows certain configuration but I can’t set the “passthrough” mode there.
Needless to say, I can see the inverter in every other UI, and controlling the Quattro via ve.bus control works correctly so I presume that should be working OK.
While that’s true, setting the discharge to zero is an instruction that can take several minutes to be executed.
I can’t disable the charger through the ve.bus node. I could only do it through VEConfigure, not via node-red. But I still want to put some logic onto the system, which I can only do through node-red, so I’m stuck unless I receive confirmation on something:
“If I turn on a generator from the AC input side, will setting the battery discharge to 0 rush the two AC sides to synchronize?”
My main fear is that a generator might set a voltage just under the system nominals, say 195V for a 220V grid, and the inverter doesn’t “want” to synchronize due to it, how could I force it to do it as fast as possible? Waiting several seconds is viable, but I’m afraid setting the discharge to 0 is just way too slow if it needs to be completed, it takes about 5 to 10 minutes to actually set current to 0.
