Hi all need some help I have a Quattro 48/8000 and a bmv 712 great products serving me well, but in the interest of longevity for my expensive 215amphr victron AGM battery’s I would love for the genset to remote start at say 49.5 volts and shut down when it charges to say 57 volts..... simple you would think using the BMV relays NC NO but Kohler seems to put a spanner in the equation by complicating something that you would surmise is a simple thing to do my Kohler generator is a marine model kohler 9efkozd https://www.manualslib.com/products/Kohler-7-9efkozd-3799387.html
with a digital control module that prevents overvheating low oil pressure shut down and zillion other things, I also have a Kohler remote switch Part Number: GM32335-KP1 https://citimarinestore.com/en/index.php?controller=attachment&id_attachment=2172
at the helm with hr meter not a toggle but more of a button type you press it and release it to start and push it again to stop so I’m thinking it’s a pulse of sorts that takes place to start stop gen set sent to the control board one would think the helm switch is where you would make the connection to the BMV 712 for ease of wiring because basically there beside each other from what I read in the manual for the remote helm switch wire # 4 is start and wire # 3 is stop and wire # 7 Is neutral is it possible to get the BMV to pulse or am I missing something as you would think with the tens thousands of these units that are sold this would be a common necessity for seamless operation.
i have searched the forum for a answer to this issue and I can only find something similar for a Onan Cummings brand gen set.
I just don’t want to get this wrong because I don’t want to damage the control module on the genset as I think it’s worth something like $2k and I’m sure this would of been done a zillion times before and I might add the people at Kohler in Australia have just handballed this all over the ship to no avail.
Thanks in advance
