energy storage
Flexible storage solution for homes, businesses, and smaller industries ADS-TEC’s StoraXe scalable system series covers the need for exible, medium-sized storage solutions for larger households, apartment buildings and businesses, industry, and public institutions. e new portfolio includes storage systems with an installed capacity of 30kWh to 66kWh. Systems with power of 20kW to 60kW are available for this purpose. e complete systems combine both the storage as well as the associated power electronics in one compact housing. Minimal installation work is required in existing buildings, where often limited space is available and if there is not enough space in the building, the storage systems can also be supplied in an compact, air-conditioned outdoor enclosure. e integrated emergency power function
and the comprehensive energy management system
(EMS) make these products suitable for a wide range of applications. In addition to "day-night shift", the energy management solution also includes an automated load peak shaving function. e integrated emergency power function also turns the system into a backup power system, providing a stable power supply in the event of a potential power failure. With o -grid and black start functions, the new series is suitable for o -grid applications. ADS-TEC o ers a solution for these applications, providing intelligent hybrid control of generators and consumers with high- performance hybrid storage systems.

Flexible commercial storage system
“Large, yet exible” is becoming an increasingly important feature when it comes to energy storage systems. e AC-coupled VARTA ex storage energy storage system is suitable for plants with a nominal system capacity of between 36kW and 600kW, and a useful capacity of between 52kWh and 750kWh. As a result, VARTA large-scale storage systems can be used in a variety of di erent ways: to increase own consumption, for peak shaving and tenant power solutions, as well as emergency power supplies.

LED lighting for the energy storage industry
e Protecta X LED, from Chalmit, has a user- de nable light distribution, a maintenance-free lifespan of over 120,000 hours at 77°F (25°C), is easy to maintain, and with its optional battery stick, can be installed quickly. e Protecta X has specialized optics which deliver the output of a 4ft linear in a lightweight and slimline luminaire package. e optics control the light, generating a highly targeted, bright, white output over the desired area, and limiting the amount of wasted spill light. e optics are available in a variety
of distinct distributions, designed for key site applications, such as mounted from handrails for walkway illumination and localized lighting in low/medium bay applications. is high, focused output means fewer luminaires are required, reducing installation and inspection times and overall project costs within an energy storage and power plant. Furthermore, the Protecta X is 50% more energy e cient than a uorescent luminaire, reducing energy costs too. e Protecta X’s LEDs and driver are housed in separate enclosures, extending the life of both components. Air gaps between the luminaire and central body prevent the collection of
dust and particulates, which helps avoid overheating. Made of recyclable marine grade aluminium, heat is conducted away from the new luminaire’s central body.

Low cost, high performing, utility-scale inverters
With over 500MWs of energy storage deployed worldwide, Dynapower is pleased to introduce
its next generation of utility-scale energy storage inverters. e air-cooled CPS-1500 and CPS-3000 are available in both indoor and outdoor con gurations, and work with all battery chemistries. Each feature
a high-e ciency, three-level topology designed for both grid-tied and microgrid applications. e Gen 4 CPS inverters also feature Dynapower’s proprietary Dynamic Transfer technology, which allows for the seamless transfer from grid-tied to microgrid mode, and Black Start capabilities. Multiple CPS units can be paralleled together to meet the sizing and power needs of any energy storage installation.

DC coupled solar + energy storage solution
Alencon Systems LLC’s SPOT (String Power Optimizer and Transmitter) is a string level DC-DC optimizer which optimizes the power from PV string inputs with voltages ranging from 600V to 1500V. e SPOT-ES family of products has been speci cally designed for the needs of DC-coupled Solar + Storage deployments. e SPOT-ES V5 includes a true 1500V input based on 1700V rated Silicon Carbide (SiC) rated mosfets, an ability to map a wide battery charge/discharge voltage range, reliability enhancements developed in concert with Solar + Storage technology providers and integrators, as well
as exible communications options for better integration with Solar + Storage and Microgrid control systems. e SPOT-
ES’s galvanic isolation concept isolates the PV input from the output by attaching isolation transformers to each PV input.
is technique provides a unique bene t in the DC-coupling of Solar + Storage because the integral magnetics to the SPOT can be easily con gured from one deployment to another to easily support a broad battery charge/discharge DC-bus voltage, where the voltage range could vary by as much 20% from complete discharge to full charge. e SPOT-ES V5 includes an ultra-fast circuit to protect it from sudden system power output overloads. e SPOT-ES V5 features enhanced communications features to allow it to be interfaced with third party system controllers via either Modbus TCP, for communicating to the SPOTs wirelessly, or Modbus RTU, which allows for hardwire communication to each SPOT directly. e enhanced communication functionality o ered in the SPOT-ES V5 allows for granular control over the PV, including the ability to curtail production at the string level.

Energy management solution
Rhombus Energy Solutions’ VectorStat Energy Management System (EMS) software is a distributed EMS software package providing reliability, security, and resiliency over a variety of network con gurations. VectorStat’s open architecture is easy
to customize and extend, allowing companies to quickly and economically adapt VectorStat to new hardware and network con gurations. VectorStat’s open, distributed architecture allows new features and open source software to be easily integrated, speeding time-to-market for new solutions, and speeding the time to deploy these new solutions. VectorStat ensures that even with lost or intermittent connections, data is protected and available later when the connection is restored. VectorStat’s distributed database architecture also signi cantly enhances energy system resilience and reliability by ensuring the functionality of each node even when network connectivity is interrupted. When network connections are re-established, data is replicated across the network across encrypted communications links.
