Hi All,
A couple of questions. Today I hooked my fisher Panda dc generator onto the cerbo relais, works like a charm. (Not via a bus because of the age of the genset) The cerbo doesn’t have an option for a DC generator only AC, correct? Might be a future software upgrade? Nevertheless, it works.
The question is, do I need to connect it to the charge disconnect of the BMS or will the Cerbo pass that signal on to the generator via the relais (set to ‘no’ for off en ‘nc’ for start). It is set to operate within a certain SOG range. But does the cerbo switches it of in case of a bms charge disconnect? When the bms shuts down, the cerbo is down too so in that case the relais will be set to ‘no’ again.
Furthermore:
It could be usefull to have the generator as backup power supply for the vessel in case something happens at sea and the bms switched the load off or alternatively a (mayday only;) bypass for the load disconnect in case of a urgent situations at sea where safety is more urgent that the lifespan of the lithiums :).
Best,
Gert Jan
