Can i use the BMV 712 to switch off a relay in a high voltage situation, if so how should it be wired?
The relay on the BMV 712 is a normally open relay and it closes when a alarm occurs (the relay can be reversed if required) it would be required to be reversed for you as you want the relay closed all the time so the main charge relay is activated all the time and turns off (goes open) when a high allarm occurs.
There are two relay contacts, so a connection from the battery Pos to a 2 amp fuse from the fuse to the BMV relay contact, (does not matter which one) then the other relay contact on the bmv to the main solenoid pos wire and the other neg solenoid wire to the neg of the battery.
The solenoid then will be powered until a alarm occurs
Hi Guys ,
I am new to the community and I would like to say Hi to all great people here that are so kind and help/advise other on how to get the best use of Victron products and most importantly to stay on the safe side.
In my case I seek some advise in regards on how can I use the BMV712 to protect my DYI 18650 battery pack from over/under discharge.
For solar charging I am using Victron 75/15 smart MPPT charge controller.
I am thinking to get the 2 BP100 Bluetooth version so I can program it for Li-ion chemistry and one of each for over/undervoltage disconnect.
If anybody can give some advise what is best approach in my case will be much appreciated.
