Hello, hoping is the correct section and tags, I searched this theme but I can’t find.
I need to install my LiFePO4 with Victron MPPT/Orion xs/IP22 on a 2005 Hymer with a Schaudt EBL 101 control unit.
The most correct procedure is to disconnect the original connectors/fuse from the control unit, but a user told me he installed SBP between the bus bar (IN Victron + LiFePO4) and the Schaudt (OUT), without disabling the connectors/fuse, and it’s running great for two years.
My question is: for example, with the engine running, the DC current will flow from the engine control unit to the Schaudt, which, reading the voltage value of the battery from the SBP, will send current to it, thus generating a reverse current.
How is it possible that the MOSFET system is not broken?
Is it possible that the SBP is inhibiting the charging from the Schaudt, thus allowing the alternator to operate without load and without risk?
My issue is that Schaudt said to other users that they can disconnect the d+ from engine battery, but with this I can’t use the 12v of the original fridge while running the engine.
