This installation guide is used as reference for the commissioning and as a guideline on how to use the inverter most effectively.

  • Page 6: Installation

    Solectria Renewables. 2.2 Inverter Mounting PVI 10KW / PVI 13KW / PVI 15KW inverter is made up of a NEMA 3R (rainproof) industrial enclosure containing electrical and electronic components including transformer, filters, contactor, fusing, a sealed IP65 power & control electronic inverter unit (DMGI245) and AC and DC disconnects mounted on the sides of the main enclosure.
  • Page 7 PVI 10KW / PVI 13KW / PVI 15KW Installation and Operation Manual Notes regarding mounting and placement of the inverter. Criteria for device mounting: • Because the power electronics is in an IP65 sealed enclosure within the NEMA 3R main enclosure, the inverter can be mounted outdoors.
  • Page 8 PVI 10KW / PVI 13KW / PVI 15KW Installation and Operation Manual • The cooling air exhausts at the bottom of the unit. Nothing should block the 2” clear space under the enclosure defined by the 2” tall mounting feet.
