Zendure SolarFlow 2400 AC & HEMS – Smart Off-Grid/On-Grid Energy Storage for the Netherlands, Belgium, Germany and the EU

Looking for a reliable AC-coupled energy storage system with an off-grid output socket for your home or business in the Netherlands, Belgium, Germany, or anywhere in the EU? The SolarFlow 2400 AC provides up to 2400 W of charge/discharge power at 230 V / 50 Hz, adjusts within 2 seconds from 0–2400 W, and supports a battery pack up to 17.28 kWh — featuring a durable outdoor enclosure (IP65) and Bluetooth/Wi-Fi connectivity for real-time monitoring.

What key specifications make the SolarFlow 2400 AC ideal for the EU market?

  • AC bidirectional: charge/discharge up to 2400 W (230 V, 50 Hz), on-grid and through a dedicated off-grid socket.
  • Fast power control: 0–2400 W adjustment in ≤ 2 s for dynamic load and generation balancing.
  • Battery capacity: expandable up to 17.28 kWh (48 V platform with integrated BMS).
  • Outdoor rated: IP65, operating temperature −20 °C to +60 °C (note: IP65 rating excludes the off-grid port when uncovered or active).
  • Connectivity: Bluetooth & Wi-Fi for local monitoring and control.
  • GaN technology & advanced BMS for high efficiency and safety.

How does HEMS support dynamic tariffs and zero export in the Netherlands, Belgium and Germany?

With the HEMS app, multiple modes are available to maximize self-consumption, benefit from dynamic pricing, and minimize grid export: Zenki (AI), Auto, and Expert modes — including Smart-CT, Smart-Plug, Base-Load, and Electricity-Price control.

  • Zenki AI mode: predicts solar yield, load, and energy price trends, increasing efficiency by approximately 7–21 % (up to 42 % in optimized cases). Requirements: storage + smart meter/CT, weather data, and ~7 days learning period.
  • Auto mode: automatic basic optimization, ideal for beginners.
  • Expert modes: Smart-CT (load tracking via CT/smart meter), Smart-Plug (specific device control), Base-Load (manual scheduling), Electricity-Price (charge when low, discharge when high).

What installation and environmental parameters are important for EU applications?

  • Nominal voltage/frequency: 230 V AC, 50 Hz (on-grid and off-grid terminals).
  • DC battery side: charge/discharge up to 2400 W, max 54.75 V DC.
  • Temperature range: operation −20 to +60 °C, storage −25 to +65 °C, humidity ≤ 90 %.
  • Enclosure: IP65 (see off-grid socket notice above).
Does SolarFlow 2400 AC work with my existing PV system (string or micro-inverters)?

Yes. It’s AC-coupled and designed for seamless integration at 230 V / 50 Hz. The 0–2400 W fast control within 2 seconds allows dynamic balancing for optimal self-consumption and zero-feed-in operation.

Which HEMS mode should I use with dynamic energy pricing in the EU?

Start with Auto mode. For maximum savings and zero-feed-in, use Zenki (AI) or an Expert mode (e.g. Electricity-Price or Smart-CT) to charge at low tariffs and discharge at high tariffs. AI optimization can significantly outperform CT-only control.

Is the system suitable for outdoor installation in European climates?

Yes, it features an IP65-rated housing and an operating range of −20 °C to +60 °C. Note: IP65 protection is not guaranteed when the off-grid socket is in use or its cover is open.

How far can I expand the battery capacity?

The platform supports up to 17.28 kWh of battery storage on a 48 V architecture with an integrated BMS — ideal for residential and small-commercial applications.

Note: installation and grid-code requirements may vary by country and grid operator. Specifications summarized from official documentation.
