¶ 1. Pre-Installation: Tools and Preparation
Before beginning the physical setup, ensure you have the following tools (not included in the package) and meet the environmental requirements:
¶ 1.1 Required Tools
- Electric Drill (8mm bit): Required for drilling holes for the wall expansion bolts if choosing vertical mounting.
- Level: To ensure the brackets and battery stack are perfectly horizontal.
- Insulating Gloves: Highly recommended for personal safety during cable handling.
¶ 1.2 Site Selection Standards
- Environment: Install the unit in a well-ventilated, shaded area. Avoid direct sunlight, persistent rain, and proximity to flammable materials.
- WIFI Connection: Make sure the Device is within the Wi-Fi coverage area.
- Clearance: To ensure Wi-Fi signal strength, maintain ≥ 15cm from the antenna on the device to the wall and ≥ 5cm from other objects for safety concerns.
- Surface: The floor must be solid and level to support the main unit and up to five expansion batteries.
To avoid wiring errors, identify the functional ports on the main unit: SolarFlow 1600 AC+ Hardware Overview
¶ 3. Hardware Assembly Sequence
¶ 3.1 Battery Stacking (Optional)
- Cover removal: Peel off the silicone protective covers from the battery terminals on the main unit and the expansion batteries.
- Alignment & Add-on: Stack the battery terminals at the bottom of the SolarFlow 1600 AC+ onto the top terminals of the expansion battery to complete the battery stacking. (Do not touch the metal pins of the ports with your hands or other objects).
- Connection confirmation: Press down firmly until you hear a clear "Click" sound, indicating the interfaces are fully locked.
- Capacity: You may stack up to 5 additional batteries for a maximum of 11.52 kWh.
¶ 3.2 Mechanical Stabilization
- Attach the side brackets to the SolarFlow 1600 AC+ main unit using the M4 screws.
- Position the stack against the wall, mark the hole locations through the bracket slots, and drill using an 8mm bit.
- Insert the self-sealing expansion bolts to fix the system firmly to the wall.
¶ 4. Electrical Integration
¶ 4.1 Grid (AC) Connection
- Cable Setup: Plug the 3m AC cable into the unit's upper AC port.
- Dedicated Socket: Plug the other end into a standard household wall socket.
- Cable Management: Make sure the solar and AC cables can run straight down without significant bending.
- Avoid Power Strips: With the device installed on a dedicated circuit, it shall serve as the sole power source other than the utility.The dedicated circuit shall not be shared with any other sources or utilization equipment, except equipment connected downstream of the device.
Operational Modes & Limits：
- Standard Mode (800W): The system is pre-set to an 800W output limit to comply with standard "plug-and-play" regulations.
- Premium Mode (1400/1600W): To utilise the full 1400/1600W bi-directional power, a licensed electrician must verify that the household wiring is suitable for the increased load. Once confirmed, the power limit can be safely adjusted within the Zendure App. Or you can connect the unit via a circuit breaker, which is highly recommended, in this case, a qualified electrician should follow the detailed instructions in this page.
[!Note]
When using a single unit, the peak power is 1400W. When an expansion battery pack is added, the peak power increases to 1600W.

Connect each inverter to a socket on a dedicated circuit for each phase, ensuring no other appliances share the same circuit. Press and hold the button for 2 seconds to power on each inverter. |
- Each inverter’s peak power can reach 1400W/1600W. Connecting multiple inverters to the same circuit can cause the circuit to overload, leading to potential safety risks.
- If your home does not have the required sockets and circuits, or if you lack the electrical knowledge to accurately identify whether these sockets or circuits meet the requirements, please request the assistance of an electrician. It is recommended to connect each inverter directly to a separate breaker. For detailed instructions, refer to this page.
- The total maximum output power of all inverters is set to a default of 800W. If you need to exceed this limit, please invite an electrician to your home to ensure your wiring is safe and does not exceed the circuit load, or follow the installation guidelines in this page to connect each device directly to the breaker.
Next, you need to complete the device software connection on the app: SolarFlow 1600 AC+ Software Setup Guide
