Dear Zendure Users,
We have collected the discussions in the forum regarding the SolarFlow Mix Series, and hope to centrally answer your following questions:
🔹 How can users unlock the maximum on-grid output power of the SolarFlow Mix Series in a compliant way?
🔹 Does the SolarFlow Mix Series support external expansion batteries? Is it compatible with previous battery packs?
🔹 The device is quite heavy, how to move and secure it safely?

Q1: How can users unlock the maximum on-grid output power of the SolarFlow Mix Series in a compliant way?
The SolarFlow Mix Series has a default on-grid output power of 800W, making it suitable for standard plug-and-play use with a household socket.
Subject to local regulations, socket load capacity, and installation conditions, the system can support up to 3000W on-grid output when connected to a household socket. For users who want to unlock higher output power, the SolarFlow 4000 Mix Pro and SolarFlow 4000 Mix AC+ can achieve up to 4000W on-grid output through professional hardwired installation.
Please note that the maximum output capability of the device is not equivalent to the grid-tied power allowed by your local regulations. Higher on-grid output must be installed by a qualified electrician and configured according to local regulations, the household electrical system, and grid connection requirements.
In short: default 800W; up to 3000W via household socket; up to 4000W for SolarFlow 4000 Mix Pro / SolarFlow 4000 Mix AC+ through compliant hardwired installation.
Q2: Does the SolarFlow Mix Series support external expansion batteries? Is it compatible with previous battery packs?
Expansion capability varies by model. The SolarFlow 4000 Mix Pro and SolarFlow 4000 Mix AC+ support external expansion batteries, helping users achieve higher capacity, longer backup time, or a larger energy storage system. The SolarFlow 3000 Mix AC+ does not support external expansion batteries.
Please note that the SolarFlow Mix Series adopts a new system architecture, battery management logic, and communication solution. Therefore, it does not support previous low-voltage expansion battery packs. In other words, earlier battery packs used by previous SolarFlow models cannot be directly connected as external expansion batteries for the SolarFlow Mix Series.
The specific compatible expansion battery models and specifications for the SolarFlow Mix Series are expected to be announced in Q4.
In short: SolarFlow 4000 Mix Pro / SolarFlow 4000 Mix AC+ support expansion; SolarFlow 3000 Mix AC+ does not; and the SolarFlow Mix Series is not compatible with previous low-voltage battery packs.
Q3: The device is quite heavy, how to move and secure it safely?
The SolarFlow Mix Series is a large-capacity energy storage device and is relatively heavy. We recommend moving it with two or more people and avoiding single-person handling.
For longer-distance movement, outdoor use, or slightly uneven surfaces, users can also purchase a dedicated trolley from the Zendure store to make transportation safer and more convenient.
Before moving the device, make sure it is powered off and that all AC, PV, and communication cables are disconnected. Do not pull the device by its cables, ports, or weak structural parts. Avoid tipping, impact, or strong vibration during transportation.
For installation, place the device on a flat, stable surface with sufficient load-bearing capacity, and leave enough space for ventilation and operation. If there is a risk of children touching the device, uneven flooring, outdoor wind, or accidental impact, we recommend using Zendure’s official fixing method or anti-tip accessories for additional stability.
