Zendure SolarFlow 4000 Mix AC+
The Zendure SolarFlow 4000 Mix AC+ is a high-power modular AC-coupled all-in-one energy storage unit from the Mix series, specially designed for families that already own rooftop photovoltaic systems and want to add energy storage without replacing original inverters or rewiring large-scale circuits. It comes with a built-in 8038Wh LiFePO4 battery as base capacity, and supports flexible capacity expansion up to 50kWh to match growing household power consumption.
Core Product Advantages
- 4000W High Bidirectional AC Power & 5000W PV AC Input It delivers 800W plug-and-play output directly from standard wall sockets, upgradable to full 4000W continuous bidirectional charge/discharge power via certified electrician hardwiring. Equipped with a dedicated PV-IN AC port supporting up to 5000W input from all mainstream European rooftop inverters, fully compatible with finished PV systems for simple retrofitting without complicated reconstruction.
- Expandable Large Capacity from 8kWh to 50kWh The integrated 8038Wh base battery meets daily power demand for three-person households with annual electricity consumption around 5000kWh. Users can add matched expansion battery modules to extend total storage capacity to a maximum of 50kWh, suitable for long-term energy arbitrage and peak shaving under dynamic electricity tariffs.
- Reliable Off-Grid UPS Emergency Power Supply When grid blackouts occur, the system realizes ultra-fast 10ms UPS switchover, providing stable 3680W continuous off-grid power with 7200W surge peak to support high-load household appliances including air conditioners, heat pumps and kitchen equipment. Solar panels can keep generating power for the storage unit through the PV-IN port during outages.
- Ultra-Long Service Life & High Energy Efficiency Adopts premium LiFePO4 battery cells supporting 10,000 full charge-discharge cycles with 70% capacity retention at end-of-life, bringing around 15 years of daily cycling service life. The overall system reaches 90% round-trip efficiency to minimize energy loss during charging and discharging, cutting household electricity bills by up to 88%.
- Mobile IP65 All-Metal Cabinet & Multi-Layer Safety Protection Robust silver metal enclosure with IP65 dust and waterproof rating, stable operation range from -20°C to 55°C for indoor, balcony and outdoor placement. Four lockable moving casters support flexible relocation. Built-in ZenGuard dual BMS and integrated aerosol fire suppression system effectively prevent thermal runaway, overvoltage, overcurrent, overheating and short-circuit risks.
- ZENKI 2.0 AI Intelligent Energy Management & Multi-Connection Powered by upgraded ZENKI 2.0 AI algorithm, the system automatically monitors real-time PV generation, household load, dynamic grid tariffs and weather forecasts to optimize charge and discharge cycles. It supports Wi-Fi, Bluetooth, LAN and RS485 multi-channel connection, enabling remote data viewing and parameter adjustment via the Zendure App, with native Home Assistant integration for smart home linkage.
- Cost-Effective Retrofit Solution for Existing Solar As an AC-coupled dedicated retrofit model, it retains customers’ original PV inverters and most wiring, greatly reducing installation cost and construction time. It is the ideal upgrade option for European households with pre-installed rooftop solar systems seeking self-consumption improvement and energy bill savings.
