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 between 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 along the groove guide
  • 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 one 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!

 

Stripping the 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 one 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 one 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.

Connecting the AC-BACKUP

Inverter vision one is designed for operation on the single-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 (red ring) is included in the Inverter vision one box.

  • Remove the transport protective covers from the AC-BACKUP port on the inverter

ATTENTION

A flat screwdriver is required to loosen the transport protective cover of the AC backup connection. Insert the screwdriver into the nose of the protective covers and then turn it to the left (see illustration).

If this is done incorrectly, there is a risk that the latches on the inverter plug break off. If the latches have broken off, the device must be returned to Solarwatt, as the BACKUP cable can no longer be securely locked in place.

Loosening the protective covers of the AC-BACKUP connection for transportation
  • Strip 40 mm of the AC cable
  • Shorten the N conductor and L conductor by 9 mm so that the PE conductor can establish a connection all the way to the end of the cable
  • Strip 9 mm of PE, N and L insulation
  • Crimp on wire end ferrules

ATTENTION

For safety reasons, the PE conductor must be longer than the N and L conductors to ensure a constant PE connection until the cable is disconnected.

Strip, strip, use ferrules
  • Feed the AC-BACKUP cable through the AC-BACKUP plug
  • Connect the cable cores to PE, N and L as marked on the plug
  • Screw the plug together
  • Listen for an audible 'click' sound, which indicates the assembly has successfully locked in place
Configuring the AC-BACKUP plug
  • Connect the AC cable to the AC-BACKUP port on the inverter
  • Turn the plug ring to the right until it audibly locks into place

Note

How do I remove the AC-BACKUP cable from the inverter if necessary?

Insert a narrow screwdriver into the nose of the plug ring, carefully turn the plug ring to the UNLOCK position and pull out the plug.

Connect AC-GRID

Inverter vision one is designed for operation in the single-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-GRID plug (white ring) is included in the Inverter vision one box.

  • Remove the transport protective covers from the AC-GRID connection on the inverter
  • Strip 55 mm of the AC cable
  • Shorten the N conductor and L conductor by 9 mm so that the PE conductor can always establish a connector right to the end
  • Strip 9 mm of PE, N and L insulation
  • Crimp on wire end ferrules

ATTENTION

For safety reasons, the PE conductor must be longer than the N and L conductors to ensure a constant PE connection until the cable is disconnected.

Strip, strip, use ferrules
  • Feed the AC cable through the AC-GRID plug
  • Connect the cable cores to PE, N and L as marked on the plug (torque 3.0 ± 0.2 Nm)
  • Tightly screw the assembly into place, listening out for an audible 'click' sound
Assembling and closing AC-GRID plugs

Note

How do I open the AC-GRID plug again if necessary?

Use the tool supplied with the AC plug (blue plastic bracket) and insert it between the locking tabs on the plug (see image below).

Fit the opening tool and push the plug out towards the front
  • Connect the AC cable to the AC-GRID port on the inverter

Note

How do I remove the AC-GRID cable from the inverter if necessary?

Insert a narrow screwdriver into the nose of the plug ring and pull out the plug.

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 one box.
