ADS-TEC Energy commercial storage systems

For the industrial and commercial storage, ADS-TEC Energy offers two product series. One is the PowerBooster, an outdoor battery system, and the other is the StorageRackSystem, a battery system designed for indoor use. Both the PowerBooster and StorageRackSystem batteries are equipped with the in-house, cloud-based Big-LinX^® Energy software. It provides simple solutions for controlling and monitoring the battery system. The installed energy storage systems can be accessed worldwide via the Big-LinX^® Energy Cloud using a smartcard secured VPN. This is particularly important for commissioning, service purposes and monitoring. In addition, the software enables system monitoring at cell level, which is important for the sustainability of ADS-TEC Energy's commercial storage systems. This is because irregularities are detected promptly, and solutions can be found quickly. The following ADS-TEC Energy commercial storage systems can be found in the Memodo online shop:

* The SRS2543 will be available from the end of June 2023, the PowerBooster GSS0813 from the end of May 2023.

Depending on customer requirements, ADS-TEC Energy's commercial storage systems can be used in different operating modes. However, the use of smart meters is necessary in all applications, only the number varies depending on the requirements. The following smart meters are approved for use with the manufacturer's commercial storage systems:

• Siemens (PAC4200)
• Janitza (UMG 604-E)

This table shows which is the right smart meter:

The most important difference between the two smart meters is the availability of the charger clearance function. This is important for the settings in the energy management system (EMS) and therefore plays a key role in the integration of DC charging poles. Only the Janitza UMG 604-E has this option. The smart meter is mandatory after the public grid and before each DC charger as well as before one or more wallboxes or charging poles. All other smart meters are only required for monitoring purposes only.

The integrated Big-LinX® software can manage different operating cases, as shown in the table below. Optimally, Big-LinX® works in combination with up to five storage systems or different charging poles. If certain parameters need to be set, such as not using grid electricity to charge electric cars, ADS-TEC recommends Energy Smart1 as the EMS.

The multiple applications can be set either on a time basis or with the State of Charge (SOC) function. For example, with the time variant, the customer can specify that consumption is always extremely high between 2pm and 7pm and that the storage system should focus on peak shaving during this period. The rest of the time, the focus is logically on optimising self-consumption. When using the SOC variant, for example, 40% of the power is always reserved for peak shaving (including grid charging), while the rest is used to optimise self-consumption.

ADS-TEC Energy solutions are (or have been) used in the following projects and are making their contribution to the energy transition.

• In 2021, the "car park of the future" was opened in the German city of Nuremberg, with 128 charging points powered by PV energy. N-Ergie's project focuses on digitalisation and testing new charging concepts for city centres. The car park produces 100 kWp of PV power on its own roof. This energy is stored using a 112 kWh/100 kW ADS-TEC Energy battery system.
• In the 'Electricity bank' project, 18 residential and commercial customers were given virtual 'bank accounts' via an internet portal to access a 100-kWh district energy storage system. ADS-TEC Energy played a key role as the supplier of the container battery system and the Big-LinX® application, which allowed stored PV electricity to be bought and sold. The project won the Stadtwerke Award in 2016.
• The educational car parks at Esslingen high school in Germany have PV systems mounted on the carports. Surplus PV energy is stored in an ADS-TEC Energy outdoor storage system. The Mini-PowerBooster buffers a 30 kWp PV system installed on the roof with 60 kW/kWh. This is how the charging poles in the educational car park are supplied with electricity.

The storage systems from ADS-TEC Energy are suitable for various applications and are developed and produced in Germany. This applies in particular to the SRS2543 and the GSS0813 with its emergency power function. Both will be launched in mid-2023. What's more, ADS-TEC Energy's products can even eliminate the need for an external energy management system. For the most common applications, the in-house software solution Big-LinX^® is sufficient.

• The manufacturer's headquarters and production facilities are located in Germany..
• The integrated Big-LinX^® software takes care of standardised applications, otherwise the commercial storage systems are compatible with Smart1.
• Over its 10 years of existence, ADS-TEC Energy has already carried out a large number of successful reference projects.
