FAQs

Yes. RelyEZ has already deployed multiple energy storage projects in Europe, especially in Hungary and Poland.
One representative project is the 110 MWh standalone BESS project in Oroszlány, Hungary, which supports grid stability and renewable energy integration. The project adopts our GridUltra5016 liquid-cooled battery system, PCS & transformer integrated solution, and EMS platform.
In addition, we are continuously expanding our project footprint across the European market.
RelyEZ has established a dedicated technical support office in Budapest, Hungary, to provide localized service and rapid response for European customers.

We provide:
7×24 remote technical support
Local technical engineer coordination
Online EMS monitoring and diagnostics
Spare parts and troubleshooting support
Fast response mechanism during system operation

Our EMS platform also supports real-time monitoring, alarm management, and intelligent diagnostics to ensure stable and reliable system operation
Yes. Our BESS solution is designed with a modular architecture, which supports future capacity expansion and flexible adaptation to different application scenarios.

The system can be widely applied in:
Grid-side energy storage
Renewable energy integration
Peak shaving and load shifting
Microgrid applications
Industrial & commercial energy management

In addition, the EMS platform supports multi-unit coordination, power distribution management, and cross-platform integration, making future expansion and project scaling more convenient and cost-effective.
