  • Page 12: Unit Information

    WYIN5K 3.2 Unit Information The unit is bidirectional, which is suitable for PV system with battery storage. The energy generated by the PV system is primarily used for load consumption. Any excess energy is used to charge the battery directly injected into the public grid. In the event that the energy output from the photovoltaic is insufficient to support the connected load, the system will automatically draw energy from the battery if it has sufficient capacity.

  • Page 13: Inverter Storage

    If any damaged or missing components are noticed, please contact WANROY. Do not dispose of the original packaging. If you need to transport the unit, it is recommended to store it with the original packaging.

  • Page 14: Installation And Electrical Connection

    All wiring and electrical installations should only be performed by a qualified electrician. Carefully remove the unit from its packaging and inspect it for any external damage.If you find any issues, please contact WANROY.

Install the inverter vertically or at a maximum backward tilt of 15°, ensuring that the connector is at the lower end of the inverter.
  • Page 17 WYIN5K Ensure adequate heat dissipation by following the minimum clearance requirements from walls, other inverters, or objects, as shown in the table below and in Figure 6. Figure 6 Multiple installation clearance reference (Refer to Figure 7) It is essential to maintain adequate clearance between individual inverters to prevent the circulation of ambient air from adjacent units.
  • Page 18 WYIN5K Installing the Wall Mount To avoid electric shock or other injury, check the existing electrical wiring system or plumbing installation before drilling bracket fixing holes. The size of the bracket is shown in figure 8(4 expansion screws, 2 wall screws). Figure 8 Using the mounting frame as a template, drill holes as shown in Figure 9.
  • Page 19 WYIN5K PLEASE NOTE: The warranty will be void if the inverter is damaged due to the use of mounting fixtures that are not strong enough to support the weight of the unit or if the equipment is damaged due to installation that does not comply with the manufacturer's requirements. Wall mounting A fall can result in equipment damage and other fatal injuries.
  • Page 20 WYIN5K Figure 11 Inspection of Inverter Installation Status Try to lift the inverter from the bracket to check the installation of the inverter. The inverter should be firmly inserted into the card slot. Please make sure to choose a suitable mounting surface to ensure that the inverter is stable and shake-free.
