Photonic Universe TBB Power Matrix-II 15kW Hybrid Transformer-Based Inverter Charger

Product Description

The MRX-48-15KP is a powerful 15kW Matrix-II hybrid transformer-based inverter charger designed for reliable backup power, off-grid applications, and seamless energy management. With advanced flexibility, multiple AC inputs and outputs, and high surge capability, the Matrix-II is ideal for residential and commercial energy storage solutions. Its ultra-fast 0ms transfer time ensures uninterrupted power supply, making it suitable for critical applications and off-grid installations.

Key Features:

1. Intelligent and high-capacity solar input


Supports up to 600V solar input, allowing for a large solar array to be integrated into the system.
Features four independent MPPT trackers, enabling optimal solar harvesting and up to 17.5kW total solar input (5kW per tracker).
Maximises solar energy capture, ensuring efficient power generation and reducing reliance on grid or generator power.
Supports AC coupled PV, DC coupled PV, or a combination of both.
Compatible with SP600-120 to achieve higher efficiency in DC Coupled PV systems.




2. Ultra-fast 0ms transfer

When AC input meets the required voltage, frequency, and waveform quality, Matrix-II switches power directly to AC output, acting as a battery charger while loads are powered by AC input. In case of AC input failure or excessive AC input current, the system instantly takes over to ensure an uninterrupted power supply. With an ultra-fast transfer time of 0ms, the Matrix-II functions as a reliable UPS for critical applications.

3. ESS and grid-tie capabilities

Seamlessly integrates with the E4 LCD Monitor and IC-METER,unlocking advanced Energy Storage System (ESS) and grid-tie functionalities. This allows for real-time monitoring, efficient energy management, and smooth interaction with the grid, ensuring a versatile and future-ready power solution.

4. 100A transfer switch

The AC transfer switch inside the MRX-48-10KP is rated up to 100A, allowing for up to 23.0kW of power to be passed through to the loads from the AC input when the inverter is in bypass.



Additional features:

Versatile AC inputs and outputs


Two AC inputs for grid and generator (or two generators).
Two AC outputs (one is an ERTB10 terminal).




Robust surge capability

Designed to handle inductive loads such as air conditioners, refrigerators, water pumps, and other high-power appliances, ensuring stable performance under demanding conditions.

Smart energy prioritisation

Allows flexible configuration to prioritise battery charging or load powering from grid or solar energy, adapting to different application needs.

Power Assist & Power Control

Automatically balances energy flow, using surplus power to charge the battery or supplementing power deficiencies from the grid or generator. This prevents circuit overload and eliminates the need for oversized generators.

Bypass Assist function

Reduces battery discharge stress under short-term overload conditions, preventing lithium battery BMS overcurrent protection from triggering.

Flexible expansion options


Supports parallel operation of up to 3 units in single-phase systems.
Up to 9 units can be connected for three-phase applications, allowing for large-scale micro-grid setups.




Remote monitoring and control

The Matrix-II can be accessed via the Nova Web and mobile app through the TBB-KIN2 Kinergy-II Wi-Fi module, allowing for real-time performance tracking and remote adjustments.

System wake-up function

Prevents deadlock due to low battery voltage or SoC by automatically resuming operation when AC or PV input is restored.

Load protection and intelligent management


Minimises battery impact when the grid is available.
Built-in three programmable relays for automatic generator start/stop (AGS).
Intelligent fan control for reduced noise and improved thermal management.




Protection & safety features:


Overload protection: Automatic restart after 60 seconds; requires manual restart after three consecutive overload shutdowns.
Over-temperature protection: Shuts down under excessive internal temperature and resumes operation once normal temperature is restored.
Short circuit protection: Automatically shuts down in case of AC output short circuit; manual restart required.
Battery low voltage/SoC protection: Automatically cuts off output to prevent battery damage due to over-discharge.




For users seeking a robust and intelligent hybrid inverter solution, the Matrix-II MRX-48-15K offers a reliable, adaptable, and future-ready power solution for both off-grid and grid-interactive energy systems.
