Team BlauBox 10/21

… prepared for POC!

Storage is an essential key for the successful implementation of the energy transition to renewable energies. Team Blau GmbH, together with its partners in Europe, has developed a German product that is adaptable to customer needs, modular, scalable, clusterable to provide exactly the energy that is needed. The BlauBox, manufactured in Germany, uses components that have long proven their efficiency and quality. In order to meet the needs of a required solution in the best possible way, the components are optimally matched to each other.

Sustainability for the sake of future generations

The Team BlauBox is used for sustainable energy storage and can be powered by solar, wind or other renewable or conventionally generated energy. This energy can be used as soon as no renewable source is currently operating, for example when using solar energy during the night.

Salt-based energy storage

Sodium-nickel batteries belong to the group of thermal batteries. In 1984, a first multi-kWh prototype was successfully tested in an electric car. Today, however, this type is mainly used as stationary energy storage for the following applications:

  • Residential and commercial buildings: time-shifting use of locally generated renewable energy to maximize self-consumption of electricity, uninterruptible power supply, “power boost” to reduce electricity contract rates

  • Utility grids: peak shaving, time-shifted power supply from renewables, smart grid management support

  • Renewable energy parks: optimizing power supply by enabling time-shifted use of generated energy

  • Transmission grids: Grid frequency regulation, time-shifted provision of electricity

  • grid-connected and off-grid micro-grid applications

The use of salt-based energy sources brings a number of advantages:

  • Free of toxic material and 100% Recyclable

  • NO dangerous materials

  • NO risk of explosion even in presence of external fire

  • NO gassing or emission

  • NO valuable resalable materials

  • NO fire/water flood reaction

  • Constant performance at -40 °C to + 60°C

  • Cycling Capability > 4.500 cycles (80% DoD)

  • Integrated system (BMS) for monitoring, diagnostics and data logging

  • Up to 80% reduction in footprint and 3 times in weight than conventional Energy-Storage

  • Zero self-discharge when stored, at any state of charge

  • Scalable module in parallel

  • No memory effect

Stay in Battaramulla

Next few months …

Britta and Karl will work on site in Battaramulla. A stay of several months in Sri Lanka is planned. The flight leaves Munich on July 28th – in Sri Lanka we will stay for 10 days in a “Bubble Hotel” in quarantaine. Both are vaccinated but the procedure requires this.

Ministries, authorities and industry

As soon as the quarantine is over, we will move to our domicile in Battaramulla. We will continue the discussions started in the virtual AHK trip in person and push the topic of renewable energy.

Team Blau Gorups SMA inverters as well as FZSoNick batteries and soon panels with German origin are available to the country and our customers.

Team Blau Groups German team was able to add a supply engineer as a technically skilled sales person with decades of experience in the energy~ and air conditioning sector. He will initially support our solar~ and storage projects from Germany. In addition, chillers are among his topics.

“Waste to energy” with German technology is also brought by Team Blau Group. Here we are talking with a waste management company that would like to use this technoligy in the future.

Product lines for inverters

The next step is to hone the product lines for solar systems in terms of organization and sales. Home systems (domestic), commercial systems (rooftop, corporate supply, etc.) and industrial systems will be anchored in three marketing channels.


Together with our partners, we will make SMA as well as FZSoNick known to the population. Team Blau Group will go to the regions and give local presentations with information for the users. All companies interested in installation and assembly of solar systems are potential partners of Team Blau Group. We will offer trainings for them soon.


A broad-based initiative will focus on rooftop and corporate energy supply. We aim to help our customers with the migration from fossil to solar. That includes both auxiliary power supply and complete energy self-sufficiency.

In the projects, we will take a close look at the needs of the customers in each individual case:

  • rooftop with feed-in to the grid only
  • storage solutions with more possibilities
    • self-supply during the day
    • long term energy security 24/7 from a self-controlled source

Large Scale

Large solar plants will push the energy supply in the country towards “harvesting Sri Lanka’s resources” and gradually reduce the purchase of energy from abroad. The use of storage will be an indispensable part of the solution, ensuring grid stability and supply even at night.

Further sustainable German technology for the Sri Lankan market

  • Waste to Energy [already in portfolio]

  • Chillers with environmentally friendly refrigeration [already in portfolio]

  • Power to Gas [as soon as market-relevant results are achieved]

  • Redox flow [as soon as market-relevant results are achieved]

  • Other new methods and technologies [we are monitoring R&D and the market].

Team Blau visit at SMA Headquarters 06/21

Cora, Bastian and Britta at SMA (Niestetal, Germany)

Finally a personal visit in SMA Headquarters! Always good to get to know the partners personally – after all these video conferences. During a great day at SMA all processes, upcoming questions were discussed as well as sensible processes of cooperation defined.

Processes and operations, manufacturing and management …

This visit was about to get to know it all and also convey this experience to our customers in Sri Lanka ….
Soon even SMA people themselves will be allowed to travel again and come to Battaramulla to check all possibilities in Sri Lanka and hold trainings for SMA products on site!

Huge production plant of SMA in Niestetal/Germany – impressing!

More than 2.500 people working in this solar park .

  • Of course the total production site is covered with solar panels

  • SMA Inverters installed care for perfect connection on or off the grid

  • Founded in 1981 SMA is celebrating the 40th anniversary this year!

Heavy visitor 08/20

Funny and heavy visitor in our new premises!

Come in and we help:

Even elephants are being “served”: this one was looking for water in front of our office and gardens.
