Zendure Solarflow 2400 AC Test: AC-Coupled Storage with 86% Efficiency (heise.de)

• Round-trip efficiency 86-87% – highest in test field
• Modular up to 17.28 kWh, only compatible with AB3000X battery
• Open MQTT/Home Assistant integration via Zen SDK
• No PV inputs, less suitable for small balcony systems

"The Zendure Solarflow 2400 AC is a modular AC-coupled storage system for balcony power plants and existing PV systems. It achieved a round-trip efficiency of 86-87%, the highest in tests so far. It is tied to the AB3000X battery and offers open MQTT/Home Assistant integration. Disadvantage: no direct PV inputs, making it less suitable for simple 800W balcony systems as it doesn't utilize the DC side."
