TSUNESS launched the new micro storage solution-DC Coupled Unit (DCU) on 20^th June, 2024 at the Intersolar Munich in Germany. The purpose of event was to showcase cutting-edge innovative technology and present the best micro storage solution for the " Balcony Solar System".

In the current global context of heightened concern of climate changes and increasing energy cost, national policies within the European Union are driving the robust development of photovoltaic targets. The adoption of the "solar package 1" in May of this year is expected to stimulate further growth of balcony solar applications in Germany. As more and more balcony solar systems have been installed, there are increasing concerns regarding the efficiency of solar energy usage for local consumption, whether user can use the exact amount of energy which is produced by balcony solar system and what about the non used energy. For the existing balcony solar kit owners, TSUNESS now offers the perfect solutions - DC Coupled Unit. The introduction of this new product not only signifies TSUNESS stepping into micro storage section but also underscores its forward-thinking and innovative capabilities as an industry leader.

Safe and efficient, enabling multiple scenarios

DCU is capable of maximize solar energy into home local consumption by storing surplus solar energy in the DCU for later use, such as during night. Additionally, using optional accessory P1000, DCU can easily turn into a portable power station during power outages or outdoor usage.

Furthermore, DCU is modular design with DCU1000(1kWh) and B1000(1kWh) which offers full flexibility for different range of power requirement from 1kW to max 5kWh. It is designed for DIY scenario, fully plug and play without any requirement for professional installation, fits perfectly with existing balcony solar kit.

Six primary benefits about DCU

1. LiFePO4 battery cell, safe and efficient. Top LiFePO4 cylindrical cell offers more than 6000 cycle time and much higher power density for lightweight and compact product design. Additionally, the integration of intelligent BMS control system ensures the safety of home grid.

2. Battery modular design. With the main control unit DCU1000(1kWh) and extension battery B1000(1kW), DCU offers stackable modular combination with full flexibility from 1kWh to max 5kWh. The optional accessory P1000 is another powerful tool which can turn the DCU into portable power station for emergency power supply or outdoor usage camping.

3. Easy monitoring. With integrated WIFI, DCU can be monitored and controlled by TSUNESS Smart app real time and remotely. User can easily control the output or set the time period for different output mode.

4. Plug and play for DIY, simple and user-friendly. No professional electrician is required for setup, simple and user-friendly for end user. DCU is also compatible with most micro inverter brands in the market, ideal for existing balcony solar kit owners which are looking for storage option.

5. Optional smart meter for zero export. With optional WiFi smart meter, DCU can also have the function of zero export, with easy setup in TSUNESS Smart app, simple and accurate.

6. Reliable design for harsh environments. DCU integrated with a self-heating system, capable of operating within temperature range of -20°C to 60°C. Additionally, IP65 waterproof and dust-proof design ensures full performance against harsh outdoor conditions, thereby guaranteeing users a safe and independent power supply.

TSUNESS, leveraging its exceptional technical and extensive industry experience, has developed and launched highly competitive micro storage solution that is low-carbon, efficient, safe, and user friendly.

DCU represents a significant milestone for TSUNESS to step into micro storage section. TSUNESS will keep its market orientation, accelerate key technological innovation and breakthroughs, continue to develop high-performance, environmentally friendly, safe, and sustainable energy storage solutions, thereby contributing to the high-quality development of global energy storage industry.
