The main arena in Expo Hall No. 5 was bustling with life from early morning. Among many presentations and interesting discussions, there was also one prepared by the Exclusive Partner of the ENEX Fair – Huawei Digital Power. It was devoted to comprehensive solutions for the renewable energy sector. Paweł Bliźniuk, Solutions Manager at Photomate, and Julian Kujawski from Huawei Digital Power presented technologies for the residential, commercial, and industrial markets, as well as large-scale energy investments.

 Solutions for the residential sector

 The first part of the presentation concerned energy storage for households using the example of a system LUNA2000-7/14/21-S1.  Paweł Bliźniuk discussed the key technical parameters of the device, including the ability to configure the capacity from 6.9 to 20.7 kWh and cooperation with series inverters SUN2000. – The system uses LFP cells and can operate in a parallel configuration with up to four sets, offering up to 15 years of warranty – said the expert.

 The expert also presented sample installation configuration scenarios, including PV modules, optimisers, energy storage, cascade inverters, and the EMMA energy management system.  The operating modes discussed included strategies for maximising energy self-consumption and loading the storage facility with surplus energy from the photovoltaic installation, depending on the energy price over time.

 Systems for business and industry

The second part of the presentations focused on solutions for the sector C&I (Commercial & Industrial). Energy storage facility - LUNA2000-241-2S1, designed for industrial applications and large commercial facilities, was  presented 

 – The system offers 108 kW of power and 241 kWh of capacity in one cabinet, with the possibility of parallel operation of up to 20 units in one system managed by SmartLogger.  One of the key design elements is the hybrid air-liquid cooling and auto-adaptive thermal management system, which increases the efficiency and durability of the battery – added Paweł Bliźniuk from Photomate.

 Much attention was also paid to security architecture. – The system has multi-level protection, fast shutdown in about 5 milliseconds, cell fault monitoring and insulation to protect against electrolytic corrosion – he talked about the details.

The last part of the presentation featured Julian Kujawski from Huawei Digital Power, who presented the perspective of projects, utility-scale PV and BESS. The expert discussed the current challenges in the energy market and how to design hybrid installations that combine photovoltaic farms with energy storage systems.

 The presentation covered

•  system architecture of PV + BESS installations,
•  the importance of technology grid-forming for network stability,
•  operational strategies affecting battery degradation and LCOE,
• revenue stacking, i.e. combining various sources of revenue from energy installations,
•  issues of project bankability and financing.

 – Properly designed energy storage systems not only stabilise the operation of the grid, but also increase the profitability of investments and the resilience of projects to regulatory changes, emphasised Julian Kujawski.

 A comprehensive approach to energy transformation

 Huawei Digital Power's presentation at the ENEX trade fair showed that the development of renewable energy requires a coherent approach, from technologies for single-family homes, through solutions for businesses, to large-scale infrastructure projects. Owing to intelligent energy management, advanced storage and the integration of PV systems, it is possible to build stable and efficient energy ecosystems at every market level.
