I am using the "Two-signal BMS support" assistant with my Multiplus (24/300/70) connected to a BMS. Aux 1 is connected to a cell over voltage signal and Aux 1 is connected to a cell under voltage signal. The "Battery state inputs" window is configured as follows:
The battery if full when Auxiliary input 1 is open and the battery is empty when Auxiliary input 2 is open.
The Action window is configured as follows:
Disable charger and do not adapt SOC when battery full and switch to charger only when battery empty.
So far so good. The problem is this:
When the Multiplus is inverting and Auxiliary input 1 opens (which happens on an OVERvoltage condition), the Multiplus shuts down completely! I would expect it to disable the charger and continue inverting, since the battery is obviously full and has plenty of power. Do I have a setup problem, or is there a good reason why the Multiplus stops inverting? It seems like a bug to me.
