Inverter Positioning and Mounting
Correct mounting position for the inverter is vertical with the mounting feet on the floor or
back of inverter mounted to a wall.
The PVI 10KW / PVI 13KW / PVI 15KW
inverter is made up of a NEMA 3R industrial enclosure
containing electrical and electronic components including transformer, filter, contactor, fusing,
a sealed power & control electronic inverter unit. The AC and DC disconnect switches are
mounted on the sides of the main enclosure. On standard versions, the disconnect switches
are side facing. An option is available with forward-facing disconnect switches for tight spaces
where width is limited (see Figure 1.3).
Use the mounting diagrams in Figures 3.1, 3.2 or Figures 3.3, 3.4 to choose whether floor or
wall mounting will be used. The inverter includes mounting feet for attachment to floors, and
mounting tabs for wall mount. You can also use a combination of both mounting provisions.
For example, 2 bolts in floor mount feet and 2 bolts in the wall mount tabs.
It is recommended to use galvanized grade 5 or better bolts or stainless steel bolts. The correct
bolt size is 3/8” (10mm) diameter. Use a heavy lock washer and flat washer with each bolt. If
wall mounting is used, be sure to verify sheer and pullout strength of anchors or other wall
attachments.
WARNING:
Severe injury or death could occur if the inverter mounting fails and
the unit tips over or falls on a person.
NOTE:
The weight of the inverter will exert an added load to floor, roof or pad
where mounted. Be sure to verify proper load capacity of mounting surface.
NOTE:
If the roof/floor mounting only uses the inverter’s mounting feet, be sure
to use all 4 available foot mount bolt positions.
