Purpose-Built for Dual Battery Bank RV Installations

The Dometic SC-DB-MPPT-40-12 is a 40-amp MPPT solar charge controller engineered specifically for 12V RV systems that require simultaneous charging of two separate battery banks — typically a house bank and a chassis battery.

If your installation has a single battery bank, the Go Power! GP-RVC-30-MPPT is likely the better fit. If you're managing two banks from a single controller and need higher charge current, this is the unit designed for that job.

⚠️ Display & Connectivity Notice

Bluetooth wireless monitoring and app connectivity are only available when the PowerTrak display module is connected. If you plan to use the Go Power! app or want wireless system monitoring, select the Controller + Display Kit (Full Functionality) option above.

Choose Your Configuration

Controller Only (No Bluetooth/App)
The controller unit alone. Ideal if you already own a compatible PowerTrak display or don't require wireless monitoring.

Controller + Display Kit (Full Functionality)
Everything you need for a fully functional, connected solar controller system. Kit includes:

✅ Dometic 40A MPPT Dual Bank Solar Controller
✅ PowerTrak 3" Color Touchscreen Display (Part #83457)
