TBB DDN Series DC-DC Charger with MPPT

Charges the house battery from the alternator and solar at the same time, and can recharge a flat starter battery. 12V and 24V.

The DDN Series combines a bi-directional DC-DC charger with an MPPT solar charge controller. While you drive, it charges the house battery from the alternator. When you stop, it charges from solar, and it can share that solar with the starter battery too.

It is the charger TBB specifies for LIBERGRID. The 24V models suit trucks and larger vehicles.

• One unit charges from the alternator and solar panels, so no separate solar controller is needed.
• Charges at full rated current from both sources at once.
• When parked, solar also tops up the starter battery if it runs low.
• Engine start assist: from the app, the house battery recharges a flat starter battery, ready to start in about 10 minutes.
• Bluetooth app monitoring and firmware updates, and silent fanless cooling.
