For nearly two months, Adrien, Alexis, Olivier, and Laurent—four readers of the French website Clubic—tested the Zendure SolarFlow 2400 AC+ in their homes. Each person had a different setup, including various solar panel configurations and inverters, which allowed for a comprehensive evaluation of the product. The SolarFlow 2400 AC+ is a new energy storage system designed to connect directly to a standard wall socket using alternating current (AC). It combines an expandable home battery (ranging from 2.4 to 16.8 kWh) with a 2400 W bidirectional inverter. The system is controlled by a HEMS (Home Energy Management System) powered by ZENKI AI, which optimizes energy use based on solar production or electricity prices, especially during off-peak hours. During the initial setup, the testers generally had positive impressions of the packaging, which protected the battery well. However, Adrien noted that the battery's weight of 27 kg made it difficult to handle alone, while Olivier mentioned that the 30 kg package could be surprising upon delivery. Alexis praised the packaging and the battery’s solid construction, and Laurent appreciated the handles on the battery itself but pointed out the absence of handles on the box. Installation and setup varied depending on the user's existing electrical infrastructure. Adrien installed the battery in his garage with a reinforced socket but faced compatibility issues with his APsystems gateway. Olivier had some initial pairing problems with the battery but resolved them after waiting five minutes. He used a Shelly 3EM Wifi for monitoring. Alexis found the installation of the Smart Meter 3CT straightforward, though it required a dedicated circuit. Laurent found the Smart Meter 3CT installation more complex and noted it required some electrical knowledge. During daily use, the testers evaluated different modes of operation. Adrien used a mix of self-consumption during the day and personalized mode in the evening. Olivier tested several modes, including Zenki AI, self-consumption, automatic, and personalized, and noted the system’s quick response time. He used Home Assistant to manage the system precisely. Alexis found the system easy to use once set up and appreciated the mobile app's simplicity. Laurent found the self-consumption mode reliable but noted some inconsistencies with the Zenki mode. The savings varied among the testers. Adrien saved around 11 euros in August 2026, with a 5-point increase in self-consumption. Olivier reduced his daily electricity cost by 33%, from 3 euros to 2 euros, but noted limitations during the summer. Alexis saw an 8-point increase in self-consumption, from 40% to 48%. Laurent observed a significant drop in electricity use during peak hours and considered adding more batteries for further savings. The Smart Meter 3CT required careful installation, as it came with a default three-phase configuration that needed adjustment for monophasic setups. Zendure has since released new versions of the smart meter, the Smart Meter 1CT-S and 3CT-S, which offer a more compact design and an RJ45 port for wired communication. Overall, the SolarFlow 2400 AC+ received positive feedback for its quality, responsiveness, and versatility. However, its performance depends on having a Zendure smart meter and a compatible solar inverter. Proper electrical installation is essential to fully utilize the 2400 W power capacity. The system shows promise and could be further optimized with additional batteries.
