This has been brought up before, and after being away from the forum and not seeing the feature added in any of the software or firmware updates, I am bringing it up again.
Would be great if Victron could add more capability to the alarm mode setting of the BMV 712, specifically the ability to trigger an alarm when a Max Amperage threshold is reached.
Why?
Because most BMS’s have a max continuous current rating, sometimes even a short peak rating, and there are certain situations where auxiliary power such as Solar is able to offset some amperage draw, allowing for extra amperage to be used, but only if the panels can provide it.
If the panels see shading, the total amount of usable amperage is diminished and there is potential to exceed the max Amp draw allowed by a batteries BMS, which results in a disconnect and reset.
There are also situations where users must manage their usage based on a combination of devices, some of which have a high inrush current which can spike a system.
A lot of BMS’s can handle short overloads for a short amount of time, but having the ability to set an alarm that coincides with the specifications of a batteries BMS would be helpful to alert the user in advance, giving them a chance to avoid a battery bank disconnect.
