Given the length of the multiplus compact 2kva, i need to mount it horizontal (sideways) on the van wall to make it fit. The manual doesn't really state that it can't be done, but the mounting points included don't really lend to mounting in that orientation. I have considered creating a ledge with angle aluminum to rest it on while using the included cleat.
Is there any restriction to mounting it this way other than airflow? Ventilation is not an issue.
