The TBB Power Kinergier Mobile CM20L is a next-generation bi-directional inverter-charger designed for mobile applications. Whether in an RV, marine vessel, or utility vehicle, this powerful inverter ensures uninterrupted, high-performance energy conversion, featuring ultra-fast transfer times, high surge capability, and intelligent power management for seamless operation.

Key Features

- Power control & assist – Automatically adjusts charging current to prevent generator or grid overload, supplementing power when needed for stable operation.

- Reliable pure sine wave output – Provides clean, grid-quality power to safely run sensitive electronics like computers, TVs, and appliances, ensuring smooth and efficient performance.

- High surge power capability – Handles demanding loads such as air conditioners, water pumps, refrigerators, microwaves, and power tools with ease.

- Multi-battery compatibility – Supports AGM, GEL, Flooded, Lead-Carbon, and Lithium batteries with advanced charging algorithms for maximum efficiency and lifespan.

- Lithium battery optimisation – Built-in Battery Management System (BMS) communication ensures accurate SOC monitoring, optimal charging, and extended battery life while preventing overcharging or overheating.

- UPS-grade 0ms transfer time – Ensures a seamless switch between power sources, making it ideal for uninterrupted operation in critical applications.

- Automatic power-on with shore power – Instantly activates when connected to an external AC source, providing smooth operation without manual intervention.

- High efficiency & low standby power – Achieves up to 93% efficiency with an ultra-low 12W idle power consumption, maximising battery life and reducing energy waste.

- Remote monitoring with TBB-MCK – Seamlessly integrates with the TBB-MCK remote monitor, allowing real-time system status tracking, and fault diagnostics.

- Battery sample cable - Includes temperature and voltage sensing, enabling more accurate charging programs. Unlike standard current-carrying cable, this avoids inaccuracies caused by voltage drop, enhancing battery performance.

- 3A slave charger for starter battery - A dedicated 3A output keeps the engine starter battery topped up while the system is in standby, ideal for vehicles left unused for extended periods.

Advanced Protection & Safety Features

- Overload protection – Auto-restarts after 60 seconds, with manual reset after three consecutive overload events for enhanced safety.

- Over-temperature protection – Monitors internal temperature, automatically resuming operation once conditions stabilise.

- Short circuit protection – Automatically shuts down during an AC short and requires manual reset.

- Battery over-temperature & low-voltage protection – Prevents overheating, overcharging, and deep discharge for long-lasting battery performance.

- Ground relay – Ensures safe grounding when external AC power is unavailable, disconnecting automatically when shore power is detected.

Perfect for Mobile & Off-Grid Applications

The TBB Kinergier Mobile CM20L is designed for off-grid, campers, boaters, and professionals who demand reliable, efficient, and seamless power management. Whether you're boondocking in an RV, sailing offshore, or operating a worksite vehicle, this inverter-charger delivers unmatched performance and safety.

Stay powered anywhere with the TBB Kinergier Mobile CM20L – the ultimate inverter-charger for mobile energy solutions.
