I have a parallel multiplus system, with a BMV712, and CERBO GX connected to a FLA battery bank on my boat.
I am interested in limiting charge current when the engine alternator is producing as well as the generator as to not exceed the charge current acceptance rate of my batteries.
A method that we have discussed is using a AUX input on the master multiplus to trigger a reduction in the output capability of the multiplus units. This aux contact would be tied to a “main engine running” signal.
I am certain that this method would work, but there might be a better way.
Could I turn on DVCC on the CERBO GX and have it limit the charge current by using the value supplied by the BMV712?
That would be the best method in that it would be dynamic.
Please let me know.
