Without a battery, solar energy produced during the day that you do not consume is fed into the grid — often without compensation or at a very low rate. The SolarFlow 1600 AC+ continuously monitors your production and absorbs this surplus via its AC port. It stores it in its LFP cells, then returns it in the evening, at night or during consumption peaks. ZENKI 2.0 AI anticipates weather and rates to decide the best time to charge or discharge — including off-peak hours on a dynamic or EDF Tempo rate.

The SolarFlow 1600 AC+ is designed as a modular system: the main unit includes 1,92 kWh of LFP energy storage. By stacking up to 5 additional AB2000X batteries (1,92 kWh each), you can reach 11,52 kWh of total capacity — without replacing the main unit. Output power also increases to 1 600 W as soon as the first AB2000X battery is added. Each step adapts to your budget and the development of your solar panels.

The ZenGuard system includes a local BMS that monitors the voltage, current and temperature of each LFP cell in real time. A cloud layer enhances this monitoring with periodic analyses and anomaly prediction. In the event of abnormal overheating, an integrated aerosol system activates to contain the incident without harmful residue. The battery's self-heating ensures operation even in sub-zero temperatures. IP65 certification for indoor or outdoor installation protected from direct sunlight.

The SolarFlow 1600 AC+ connects via WiFi, Bluetooth or the physical RJ45 port for environments with an unstable signal. The Zendure app centralises monitoring: production, charge level and incoming and outgoing flows in real time. Thanks to the MQTT protocol, it integrates natively with Home Assistant, Homey and Shelly solutions — for complete automation of your home's energy management.
