Installation
The installation of a PV combiner is fairly straight forward.
Select the location to install your combiner first. Some systems
have the PV modules located close to the inverters and or
battery system. If this is the case, you can elect to mount the
MNPV6 Disco / MNPV6-250 Disco inside and run each PV
string down to the MNPV6 Disco / MNPV6-250 Disco inside
the house. This is convenient for trouble shooting and
upgrading. For longer runs the combiner will be mounted
outdoors on the pole for pole mounted PV arrays or similar
mounting for rack mounted arrays. The combiner can be
mounted in the vertical position or slanted backwards to
accommodate up to a 3/12 roof pitch. All unused holes should be blocked using RTV sealant or some similar
goop in order to keep rain and insects out of the enclosure. Care must be taken to insure that no water will get
on terminal busbars when mounted less than vertical.
The following dimensioned drawings show the location and size of knockouts available on the MNPV6 Disco
/ MNPV6-250 Disco. Note that on the MNPV6 Disco the center bottom knock out is sized for a 1 1/4”
conduit adapter. The left and right side each have a ½” knock out for either wire entry or for lightning
arrestors. Follow directions above referring to rain and insects when using side knockouts to keep water off
terminal busbars. Lightning arrestors may require a locknut on the outside in order to clear the lid.

Note: The plastic dead front fits very tight. You must first
remove the lid in order to remove the deadfront.
Remove the deadfront:
Pry off the lid as shown using something like a
screwdriver as a lever. The dead front will then come out
easily.
