Power to 24v panel - easy to isolate?

Scott SV Tengah


As mentioned in my long post about my lithium installation, I'm still trying to figure out a way to install a load disconnect solenoid that will be controlled by the Battery Management System (BMS). This would disconnect loads in the event of low voltage in one of the lifepo4 cells.


When I tried to install the Victron BP-220 battery protect, Victron's load disconnect solenoid, the 220 amp capacity was not nearly enough given that all of the loads ran through it. It melted pretty quickly. One solution suggested to me was only to have the 24v panel running through the BP-220. That makes sense because if we disconnect all power to the 24v panel, I believe all electrical devices are disabled. 

Have any of you tried to trace from the battery switch to the 24v panel? I have an A54, but I presume the SM and earlier are similar in this regard.
