The most powerful one I’ve found is the 30A model, but I see it’s an older model that doesn’t have Bluetooth connectivity and can’t be monitored but this old version doesnt have BT.
Orion XS is the newest most capable model that provides advanced connectivity and can work both as a DC-DC converter and also as a battery charger. For your setup, you will need the “XS 1400” model, it can output 50A @12V.
The highest amperage model is the older Orion 24/12-70, albeit with no connectivity whatsoever.
