Ventilation arrangement for PVS800-57 central inverter incontainer or equivalent installation

1. Background

Proper ventilation and cooling is one of the most important issues when planning a container or equivalentinstallation for PVS800-57 central inverters. It is been noted that some installation very little or not at allattention is paid for ventilation and cooling. Some basic rules is important to keep in mind when planningventilation.

NOTE! Following pictures and descriptions are examples only. Ventilation must be dimensioned and designedby professionals and according to the environmental conditions, container dimensions, location-, type- andnumber of installed PVS800 central inverter etc.

Heat dissipation and cooling air flow required for each type of PVS800 can be found from PVS800-57 centralinverters Hardware manual, document code 3AUA0000053689.

2. Principles for air flow

In all container installations, especially in face to face installation, circulation of hot air must be prevented withair baffels or ventilation channels above the cabinets. There must be enough free space above the cabinet forair channels. Recommedation min 50cm.

In the case common ventilation channel is used, due to the powerfull cooling fans of ISU section(s), hot air flowfrom ISU section(s) to ACU, ICU or DCU sections must be prevented in each case. This can be done e.g byinstalling air baffles between the sections if the hot air is guided to flow out through the side wall of thecontainer. If air outlet area is equipped with flaps opened by air flow, it must be checked that flaps can openfreely when cooling fans of PVS800 or ventilation fans of the container is started.

Alternatively hot air can be quided out by exhaust fan with sufficient air volume.

Note!When planning exhaust fan installation, it must be considered that required air volume of PVS800 isremarkable, capacity of small hardware store fans is not enough.

2.2 Back to back installation

Also in back-to back installation, circulation of hot air must be prevented with air guides or ventilation channel. Ifcommon ventilation channel for both line-ups is used, hot air flow from ISU section(s) to ACU, ICU or DCUsections must be prevented.
