The 485 communication port is intended for wired communication between devices. It can be used with Zendure Smart CT devices such as the 3CT-S and 1CT-S, and depending on the final system configuration and wiring guidelines, it also functions as a system-level communication interface for Zendure ecosystem products such as the PowerHub.

The disconnect switches are used to manually disconnect important modules during installation, wiring and maintenance, for added safety. The SolarFlow 4000 Mix AC+ is equipped with: · a PV disconnect switch · a battery disconnect switch

The unit has an integrated design with swivel castors and support legs. Before moving, ensure that the support legs are retracted and the wheels can roll freely. Always push the unit from the side, not from the front or back, to prevent tipping. If the unit needs to be lifted, a minimum of 2 to 3 adults are recommended. Once the unit is in place, the support legs must be lowered and secured. A Zendure Power Trolley is also available as an option. The unit weighs 80 kg.

The PV-IN AC port is designed for connecting a non-plug-in single-phase PV inverter. This simplifies the integration of an existing PV rooftop system into the SolarFlow Mix series. The main advantages are: · an additional installation option outside the main distribution box, · saving space in the distribution box and circuit breaker/fuse positions, · the possibility for the external PV inverter to continue charging the battery or powering off-grid loads during a power outage. If a third-party inverter produces more power than the battery can absorb and the connected loads can consume, and feed-in to the grid is not allowed, the system activates a protection mechanism.

The SolarFlow 4000 Mix AC+ is primarily designed for AC-coupled rooftop solar energy systems with storage. Unlike the SolarFlow 4000 Mix Pro, it does not utilize the same high-voltage dual MPPT DC-PV input architecture.

Yes. Via the PV-IN AC port, the system supports AC-coupled integration with a third-party single-phase PV inverter, making it highly suitable for retrofit storage applications with existing rooftop PV systems.

The off-grid AC port provides a continuous output power of up to 3680 W, with a peak power of 7200 W for 200 ms. It is a bidirectional port, which means it can both power loads and receive AC input from an external PV inverter.

Yes. Users can enable or disable the off-grid connection locally by pressing the power button twice in quick succession.

Yes. If the PV inverter on the roof is connected via the PV-IN AC path and configured as part of the system, it can continue to charge the battery and power off-grid loads during a power outage.

Because solar panels become less efficient at high temperatures, bright sunshine does not always automatically mean higher power output.

Yes. Both the SolarFlow 4000 Mix Pro and the SolarFlow 4000 Mix AC+ support additional battery packs. The system supports a maximum of 6 packs, with a total system capacity of over 50 kWh. However, the additional battery pack for the Mix series has not yet been officially released. Availability is expected to be announced in the fourth quarter.

For a single unit, the core charging and discharging capacity on the battery side is 4000 W. When additional battery packs are connected, the total charging and discharging capacity of the system can be increased to 10,000 W.

Under test conditions of 0.5C charge/discharge and an SOH of 70%, the battery cells can achieve up to 10,000 cycles.

The battery charging temperature range is 0 °C to 55 °C, and the discharging temperature range is -20 °C to 55 °C.

At this moment, no official information has been released regarding the purchase of the expansion battery pack for the Mix series. Availability is expected to be announced in the fourth quarter.

No. Expansion with earlier battery packs is not supported. For the final supported options, please refer to what will be officially announced later as compatible battery packs.

The SolarFlow 4000 Mix AC+ supports both of the following installation methods for grid-tied use: · a plug-and-play grid-tied installation for faster commissioning, and · a hardwired grid-tied installation for higher output power and a more complete integration into the home's energy system. To enable higher grid-tied power, hardwiring by a qualified electrician is generally required. The household circuit, circuit breaker, distribution board capacity, and local regulations must be checked beforehand. A separate 32A / 30mA RCBO is recommended for a hardwired installation.

No. A single SolarFlow 4000 Mix AC+ does not, by itself, support a full off-grid backup power supply for the entire home.

By connecting the system to a router or Smart CT, you benefit from several advantages: · lower communication latency, · more stable data transfer, · faster load detection and control response, · and better coordination in more advanced home energy systems.

Yes. Because the system is grid-tied, the actual feed-in/output value set must comply with local regulations, certification requirements, and installation codes. It is recommended to set the output power in the app according to local compliance rules and to have the installation checked by a qualified installer.

For long-term storage, the battery must first be discharged to 30% and then recharged to 60% every 3 months. If the battery level has dropped below 1% after use, it must be recharged to 60% before storage to prevent irreversible damage caused by a battery level that is too low for an extended period.

It is recommended to install the device in a location that: · is in the shade and protected from direct sunlight, · is well-ventilated, · is away from heat sources, standing water, and flammable or explosive materials, · and has stable Wi-Fi coverage. Leave at least 5 cm of clearance at the back of the device for heat dissipation. Additionally, a minimum of 15 cm of free, unobstructed space must be maintained on the antenna side.

The recommended sequence is: 1 Disconnect the AC power cable 2 Switch off and disconnect the third-party PV inverter 3 Switch off the device 4 Disconnect the extra battery 5 Finally, remove the PE earthing cable Full service work or dismantling must be performed by qualified personnel.

When the device is in operation, no cables may be connected or disconnected, and the terminals must not be touched. After switching off, wait at least 10 minutes before performing maintenance, so that the internal capacitors can fully discharge. Use only a dry cloth for cleaning. Corrosive chemicals or cleaning agents must be avoided.

Germany (DE) only: yes. Products from the SolarFlow Mix series are eligible for the ZenWave promo bundle. Please refer to the ZenWave page for more information.

Dynamic energy rates can fluctuate, and during some peak hours they can turn out to be more expensive than a fixed rate. For users with energy storage, a smart meter, and automated control, dynamic rates can still be attractive: they make it easier to charge at lower prices and limit consumption during expensive periods, thereby increasing the value of the storage system.

In that case, you can use an external power strip. Zendure power strip accessories are also planned.

In a quiet laboratory environment at 25 °C, the noise level is approx. 25 dB, measured at a distance of 1 m while the device is operating at half load of 2,000 W. At full power, the noise level is approx. 43 dB. The actual noise level may vary depending on the ambient temperature, operating power, and installation conditions.
