Litherra 3kW High Frequency Inverter Charger

Compact Power. High Output Charging. Built for Space-Critical Installations

The Litherra 3kW High Frequency Inverter Charger is designed for installations where space and weight are critical, while still delivering reliable and powerful off-grid performance. Using advanced high-frequency inverter technology, it provides pure sine wave output in a compact and lightweight form, making it ideal for modern motorhomes and campervans where installation space is limited.

Despite its compact design, the unit delivers exceptional performance with a powerful 200A integrated battery charger, allowing rapid battery charging and efficient recovery of large lithium battery banks. Automatic AC pass-through allows shore or generator power to supply loads directly when available, while advanced features such as Litherra Shore Assist enable the system to support low-amperage shore supplies by supplementing power from the battery when required.

Built-in Bluetooth connectivity allows smart monitoring through the Litherra app, and like all Zenith products, the inverter can be fully integrated into the Zenith System for complete monitoring and control from anywhere in the world.

Zenith System Compatibility & Expansion

Like all Litherra Zenith products, the 3kW High Frequency Inverter Charger is designed to operate as part of a fully integrated and expandable system. When connected to the Zenith Control Unit and display system, it allows real-time monitoring of inverter performance, battery charging activity, and system load behaviour.

Combined with Zenith charging systems, distribution units, and battery monitoring components, it forms part of a fully integrated off-grid solution capable of supporting demanding electrical loads while maintaining a compact and efficient installation layout.
