Litherra Duo

Dual Charging. Maximum Power. Ready for High-Performance Systems.

Litherra Duo is a high-performance dual charging unit that combines DC-DC and solar MPPT charging into one powerful system, delivering an industry-leading 100A DC-DC charger and 80A MPPT controller in a single integrated unit. Built without compromise, Duo is designed for users running large lithium battery banks who need fast, efficient charging to get the best performance from their batteries.

By integrating both charging functions into one unit, Duo reduces wiring complexity and allows a single battery connection instead of multiple independent chargers, saving installation time, reducing cable costs, and simplifying system design. Built-in Bluetooth connectivity and support for the Litherra smart app provide real-time system monitoring and control, while bi-directional charging automatically maintains the starter battery once the leisure battery is full.

In the event of a flat starter battery, the built-in starter assist function allows the leisure battery to be used to start the engine when needed.

High-Power System Integration

Duo is built to work alongside high-power Litherra inverter chargers, handling DC and solar charging while inverter chargers manage AC charging at up to 200A and provide reliable 240V off-grid power. Together, they form the backbone of high-output off-grid systems capable of supporting demanding electrical loads while maintaining clean, efficient installations.

(This reads cleaner than “handle the AC to DC charging” from Duo’s side, since the inverter charger is the AC handler.)

Zenith System Compatibility & Expansion

(Aligned with Trinity — this should become a standard section)

Like all Litherra Zenith products, Duo can be used as a standalone solution or fully integrated into the Litherra Zenith System. When combined with other Zenith components, including the 12V control unit and touchscreen display, the system can monitor and manage all power flowing into and out of the battery, providing complete system visibility while allowing the installation to grow as power demands increase.
