SolarFlow 3000 Mix AC+

The 485 communication port is designed for wired device-to-device communication. It can be used with Zendure Smart CT devices such as the 3CT-S / 1CT-S, and also serves as a system-level communication interface for Zendure ecosystem products such as PowerHub, depending on the final system configuration and wiring guide.

The isolator switches are used to manually disconnect key modules during installation, wiring, and maintenance for improved safety. SolarFlow 4000 Mix AC+ includes: a PV isolator switch a battery isolator switch.

The unit uses an integrated caster-and-support-foot design. Before moving it, make sure the support feet are retracted and the casters roll freely. Always push from the side, not from the front or rear, to avoid tipping. If lifting is necessary, at least 2–3 adults are recommended. Once the unit is in place, lower the support feet and secure it properly. An optional Zendure Power Trolley is also available. The unit weight is 80kg.

The PV-IN AC port is designed for connecting a non-plug-in single-phase PV inverter, making it easier to integrate an existing rooftop PV system into the SolarFlow Mix Series. Its main benefits include: · providing an additional installation option outside the main distribution board, · saving distribution-board space and breaker positions, · allowing the external PV inverter to continue charging the battery or powering off-grid loads during an outage. If a third-party inverter produces more power than the battery can absorb plus the connected loads can consume, and export to the grid is not allowed, the system will activate protective control.

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

Yes. It supports AC-coupled integration with a third-party single-phase PV inverter via the PV-IN AC port, making it well suited for retrofit energy storage applications for existing rooftop PV systems.

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

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

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

Because solar modules become less efficient at higher temperatures, strong sunlight does not always result in higher power output.

Yes. SolarFlow 4000 Mix Pro and SolarFlow 4000 Mix AC+ support add-on battery packs, with up to 6 packs supported and a total system capacity of more than 50kWh. The dedicated Mix Series add-on battery pack has not been officially released yet. Availability is expected to be announced in Q4.

For a single unit, the battery-side core charge/discharge capability is 4000 W. With additional battery packs connected, the system’s total charge/discharge capability can be increased to 10,000 W.

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

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

At present, purchase information for the add-on battery pack for the Mix Series has not yet been officially announced. Availability is expected to be announced in Q4.

No. It does not support expansion with earlier battery packs. Please refer to the officially announced compatible battery packs for the final supported options.

The SolarFlow 4000 Mix AC+ supports both: · plug-and-play on-grid installation for faster deployment, and · hardwired on-grid installation for higher output and more formal home energy integration. To unlock higher on-grid power, hardwiring by a qualified electrician is typically required. The household circuit, breaker, distribution board capacity, and local regulations should all be confirmed in advance. A dedicated 32A / 30mA RCBO is recommended for hardwired installation.

A single SolarFlow 4000 Mix AC+ unit does not support whole-home off-grid backup by itself.

Connecting the system to a router or Smart CT helps provide:

• lower communication latency,
• more stable data transmission,
• faster load sensing and control response,
• and better coordination in more advanced home energy setups.
  
  

Yes. The system is grid-tied, so the actual on-grid output setting must comply with local regulations, certifications, and installation requirements. It is recommended to configure the output in the app according to local compliance rules and have the setup checked by a qualified installer.

For long-term storage, discharge the battery to 30%, and then recharge it to 60% every 3 months. If the battery has dropped below 1% after use, recharge it to 60% before storage to avoid irreversible damage caused by prolonged low battery level.

It is recommended to install the unit in a location that is:

• shaded and protected from direct sunlight,
• well ventilated,
• away from heat sources, standing water, and flammable or explosive materials,
• and covered by stable Wi-Fi.

Leave at least 5 cm of clearance behind the unit for heat dissipation, and at least 15 cm of unobstructed space around the antenna side.

The recommended sequence is:

• 1 disconnect the AC power cable,
• 2 turn off and disconnect the third-party PV inverter,
• 3 power off the unit,
• 4 disconnect the add-on battery,
• 5 and finally remove the PE grounding cable.

Full service or removal should be performed by qualified personnel.

Do not plug or unplug cables or touch wiring terminals while the unit is operating. After power-off, wait at least 10 minutes before maintenance so internal capacitors can fully discharge. For cleaning, use only a dry cloth and avoid corrosive chemicals or detergents.

Dynamic tariffs can fluctuate, and some peak periods may be more expensive than a fixed tariff. But for users with storage, smart metering, and automated scheduling, dynamic tariffs can make it easier to charge at lower prices and reduce consumption during expensive periods, increasing the value of the storage system.

You can use an external power strip. Zendure-branded power strip accessories are also planned.

Under 25°C quiet-lab conditions, the noise level is approx. 25 dB when measured at 1 m distance with the unit running at 2,000W half load. At full power, the noise level is approx. 43 dB. Actual noise may vary depending on ambient temperature, operating power, and installation conditions.
