Der Zendure Hyper 2000 ist ein Hybrid-Wechselrichter, der durch Erweiterung mit den Batterien AB1000S oder 2000S zum Speichersystem wird.

Overview

  • Germany's balcony photovoltaic systems continue to grow in popularity, with registrations nearing 870,000 as of mid-May 2025 under the Solarpaket 1 framework.
  • New AI-driven storage systems, including the EcoFlow Stream Ultra and Anker SOLIX Solarbank 3 Pro, optimize self-consumption while adhering to the 800 W grid feed-in limit.
  • Zendure AIO 2400 and Hyper 2000 systems offer scalable capacities and bidirectional charging, with prices dropping to as low as €749 and under €300 per kWh, respectively.
  • The APSystems EZHI hybrid-parallel storage system provides up to 40 kWh capacity and supports dynamic tariffs, reducing energy costs and increasing efficiency.
  • These advancements highlight the role of decentralized energy solutions in Germany's energy transition, despite the lack of state subsidies for mini-PV storage systems.
