This page outlines the mounting and cable connection process for installing the three-phase SOLARWATT Inverter vision three inverter.
Table of contents

    Mount the inverter

    Observe all Safety Instructions and requirements for the installer.

    Observe the Specifications for the installation location and the maximum and minimum installation distances for the inverter, meter and battery.

    Check whether the condition of the wall and the enclosed mounting material are suitable for supporting the product weight of the inverter (22 kg).

    Do not rest the inverter on its connection ports or front panel.
    • Mark, then drill the screw holes for the wall bracket
    • Mount the wall bracket
    Mounting the wall bracket
    • Carefully hang the inverter on the wall bracket
    • Screw the inverter into both sides of the wall bracket

    Connect the PV DC cable

    Observe the Information on cable requirements and minimum bending radii for inverter, meter and battery.

    Observe the Explanations on the Crimping PV plug connectors.

    Inverter vision three includes Stäubli MC4 Evo 2A PV connectors in the box, which are compatible with the Stäubli PV connection sockets on the inverter. Stäubli PV plugs are compatible with other types of Stäubli MC4 plugs.

    • Strip the PV DC cable to a length of 6.0 - 7.5 mm
      Make sure that no individual wires are damaged!
    • Crimp the DC cable with the PV plug connectors 
      Ensure correct polarity when assigning the PV pin contacts!
    Strip PV cable
    • Connect the DC PV cable to PV+ and PV- on the inverter.
      Listen for an audible 'click' to ensure the connector makes contact.
    • Pull on the DC PV plug connectors to ensure they are fully engaged.
      (control force: max. 20 N)

    ATTENTION

    Cable couplings that are not fully engaged (see illustration below) can lead to permanent deformation of the locking hooks, causing damage to the locking mechanism of the plugs. Always check that the cables have been fitted correctly.

    Plug connectors together right / wrong

    Note

    How do I remove the Stäubli Evo 2A plug from the inverter if necessary? 
    To remove the plug, use the Stäubli tool PV-MS-PLS/2 or PV-MS (not included with the inverter). Alternatively, a screwdriver can be used to open the side locking lugs on the PV plug.

    Connect the DC battery cable to the inverter

    The Battery DC cable is included in the Battery vision top pack box.

    • Connect the plug to BAT+ and BAT-
      Listen for an audible 'click' to ensure the connector makes contact.

    ATTENTION

    Always use the battery DC cables included in the box for connecting the battery and inverter. The use of third-party cables risks voiding the warranty of the Battery vision/Inverter vision system.

    Screw in the antenna (for Bluetooth support)

    The antenna is included in the Inverter vision three box.

    • Remove the protective rubber sleeve from the antenna connector on the inverter
    • Screw on the antenna
    Screw on the antenna

    Connect the BMS cable to the inverter

    The BMS cable is a standard network cable and is included in the Battery vision top pack box.

    • Connect one side of the BMS cable to the BMS port on the inverter.
    • Tighten the mechanical strain reliever (this also acts as a waterproofing seal).

    Connect the inverter to the internet

    Inverter vision three must be connected directly to the router via a LAN cable connection. A LAN cable for this purpose is not included in the scope of delivery.

    • Attach the waterproof connection housing and mechanical strain reliever (included in the Inverter vision one box) to the inverter side of the plug for protection
    • Connect the other side of the cable to your router

    In exceptional cases, the inverter can be connected to a Wi-Fi network in range of the inverter to allow it to connect to the internet.

    • Ensure that the antenna is screwed in to the inverter
    • Use the SOLARWATT Pro app to configure the Wi-Fi settings on the inverter

    Further explanations on Connecting the inverter to the local network via Wi-Fi.

    ATTENTION

    Use the enclosed waterproof plug housing for the LAN plug on the inverter. Otherwise the device may be damaged by moisture.

    Connect AC / BACKUP

    Inverter vision three is designed for operation in the three-phase mains, voltage range 220/230/240 V, frequency 50/60Hz. Other technical requirements must comply with the requirements of the local grid.

    Please note the Cable requirements and bending radii for inverter, meter and battery.

     

    The AC / BACKUP plug is included in the Inverter vision three box.

    Video: Connecting the AC / BACKUP plug
    • Strip the cable end as illustrated below
    • Crimp the wire end ferrules onto the cable
    Strip the cable
    • Feed the AC cable through the AC plug components
    • Connect the cable ends of the mains connection cable and the backup cable according to the wire designation on the plug
    • Fix the locking nut
    • Connect the mains cable to the BACKUP/GRID connection
    • Close and secure the safety clip

    Connect the grounding cable

    The grounding cable is not included in the scope of delivery. However, a cable lug for connecting the grounding cable is included in the Inverter vision three box.
