  • Page 5: Introduction

    The PVI 10kW / PVI 13kW / PVI 15kW is a commercial, 3-phase grid-tied PV inverter designed to be inter-connected to the electric utility grid. With this manual the PVI 10kW / PVI 13kW / PVI 15kW can be installed and operated safely.

  • Page 6: Checking For Shipping Damage

    Solectria Renewables. 2.2 – Inverter Mounting The 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 NOTE: The 380 lb. weight of the inverter will exert as much as 100 lbs. per bolt on the 4 wall mounts. Tension on the top bolts could also be 100 lbs. Make sure an appropriate safety margin is used for both shear and tension of wall mounting bolts, anchors or other attachments.
  • Page 8 PVI 10kW / PVI 13kW / PVI 15kW Installation and Operation Manual  The ambient temperature must be between –25 C and +50 C for full power, continuous operation. The inverter will automatically reduce power or shut down to protect itself if ambient air temperature rises above 50 ...

WARNING: The grounded DC photovoltaic connection (typically the negative DC connection) is bonded to ground within the inverter through the ground fault detection and interruption circuit (GFDI).
  • Page 13 PVI 10kW / PVI 13kW / PVI 15kW Installation and Operation Manual DC Wiring: For the DC wiring without an integrated fused PV combiner, two conductors are required (one for the grounded conductor and one for the ungrounded conductor) plus additional conductors for grounds (see grounding section below).

  • Page 14: Making The Electrical Connections

    WARNING: Please follow all applicable local codes. The inverters meet and are certified to all UL1741 and IEEE1547 requirements. Solectria Renewables does not endorse any of the connections discussed below. The following are recommended courses of action that must be approved by local building officials before any connections are made.
  • Page 15 PVI 10kW / PVI 13kW / PVI 15kW Installation and Operation Manual WARNING: Before making the DC connections at the DC disconnect, check the correct polarity and admissible DC voltage between the grounded and ungrounded DC connections.

  • Page 16: Commissioning The Inverter

    The inverter operates automatically without the need for user interaction or maintenance. The PVI 10kW / PVI 13kW / PVI 15kW inverter automatically starts back feeding 3-phase AC power into the grid every morning as the sun rises, as soon as sufficient DC voltage and PV power is available. The inverter DSP runs through various checks before going online with the grid and feeding power into the grid.
