Zendure SolarFlow 4000 Mix AC+ — 8 kWh Home Battery
The SolarFlow 4000 Mix AC+ is the go-to choice for households with an existing solar installation who are serious about storage. This AC-coupled home battery connects effortlessly behind virtually any inverter and delivers 4 kW of bidirectional power. You start with 8 kWh and can easily expand later to 50 kWh with separate 7 kWh modules. Via the separate PV-IN AC port you can use up to 5 kW from your existing rooftop installation, ideal for retrofitting without rewiring. With an IP65 housing, powerful backup power and the smart ZENKI 2.0 AI, you are ready for the end of the Dutch net-metering scheme (salderingsregeling).
Why the SolarFlow 4000 Mix AC+?
Start with 8 kWh and expand modularly with 7 kWh modules as your consumption grows.
More power for larger households; in PV bypass up to 5,000 W AC output during peak hours.
Use up to 5 kW from your existing inverter — retrofit without rebuilding your installation.
3,680 W continuous and 7.2 kW peak off-grid, with switchover within 10 ms during a power cut.
Can be installed indoors and outdoors, works from -20 to 55 °C and produces only 25 dB.
Automatic charging on dynamic tariffs, with Home Assistant integration and the Zendure app.

How to connect it
- Plug into the wall socketAC-coupled and plug & play: connect, set up and use. Your existing inverter and solar panels stay in place; via the separate PV-IN AC port it uses up to 5 kW from your inverter.
- Full power on a dedicated circuitIf you want 4,000 W, an installer connects the battery to a dedicated circuit in your electrical panel. A job of about one hour.
- P1 meterWith the Zendure P1 meter on your smart meter, the battery responds to your actual consumption.
- Connectivity and mountingZendure app and Home Assistant. A unit of about 80 kg, quieter than 25 dB; indoor and outdoor installation allowed (IP65, from -20 to 55 °C). With separate 7 kWh modules you can expand to 50 kWh.
When 800 W and when full power?
In the Netherlands, a battery connected via a wall socket may supply a maximum of 800 W to your home. For an average household, that covers the base load: fridge, lighting, TV, laptop and router. If the washing machine, oven or induction hob run at the same time, the rest simply comes from the grid.
The Mix AC+ charges and supplies at 4,000 W. That covers a household's base load as well as the peaks of the washing machine, oven or induction hob; anything above that, your home draws from the grid. From empty to full takes about 2 hours.
During a power cut it supplies 3,680 W continuous and 7,200 W peak, with switchover within 10 ms. Via the PV-IN AC port it takes up to 5 kW from your existing inverter, and in PV bypass it supplies up to 5,000 W during peak hours.
