    Installing 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 place the inverter on the connections or on the front panel
    • Mark the drill holes using the wall bracket and drill the holes
    • Mount the wall bracket
    Mounting the wall bracket
    • Carefully hang the inverter on the wall bracket
    • Fix the inverter to the wall bracket

    Inverter vision three wiring

    Connect DC cable PV

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

    Observe the Explanations on the Crimping PV plug connectors.

    The scope of delivery includes Stäubli MC4 Evo 2A PV connectors, 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 DC cable PV to PV+ and PV-
      A 'click' must be audible.
    • check for correct engagement by pulling on the plug connectors
      (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 and thus to loss of the locking function. You should therefore always check that they have been fitted correctly.

    Plug connectors together right / wrong

    Note

    How to 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 in the scope of delivery). Alternatively, a screwdriver can be used to open the side locking lugs on the PV plug.

    DC cable Connect battery

    The Battery DC cable is included in the scope of delivery of the Battery vision top pack.

    • Connect the plug to BAT+ and BAT-
      You should hear a 'click'.

    ATTENTION

    Always use the battery DC cables included in the scope of delivery for connection to the inverter. Only then is the warranty on the Battery vision/Inverter vision system guaranteed.

    Install antenna (for bluetooth connection)

    The antenna is included in the scope of delivery of the Inverter vision three.

    • Remove the protective rubber sleeve from the antenna connection
    • Screw on the antenna
    Screw on the antenna

    Connecting the BMS cable

    The BMS cable is a standard network cable (included in the scope of delivery of the Battery vision top pack).

    • Connect the communication cable to the BMS output
    • Tighten the mechanical strain relief (also outdoor seal)

    Connect LAN

    The Inverter vision three is connected directly to the router via a LAN connection. The LAN cable is not included in the scope of delivery.

    • attach a waterproof plug housing (included in the scope of delivery) to the inverter side of the plug for protection and mechanical strain relief
    • Connect the inverter to the router

    In exceptional cases, a WiFi connection can be established for a wireless connector to a WiFi in the vicinity of the inverter.

    • Ensure that the antenna is screwed to the inverter
    • Use the SOLARWATT Pro app to make the WiFi settings

    Further explanations on Integrating the inverter into the local network via WiFi.

    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 public grid.

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

    The AC / BACKUP plug is included in the scope of delivery of the Inverter three.

    Connecting the AC / BACKUP plug
    • Strip and strip the cable
    • 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 lock nut
    • Connect the mains cable to the BACKUP/GRID connection
    • Close and secure the safety clip

    Connecting the grounding

    The earthing cable is not included in the scope of delivery. The cable lug for the earthing cable is included in the scope of delivery of the Inverter three.
