Just so it is abundantly clear to all that wish to modify or cut open an inverter, SMA will not do any advanced replacements of any inverters that have been modified, Outback is not a problem as they are field serviceable, SolArk is a all in one unit and any modification to the cabinet will prevent you from getting an advance replacement and increasing down time from days to weeks if not months so this may be an decision maker why not to do, I have 1 to 5 solarks on gutters with no issues getting any cabling into the unit.
