    PV inverters designed to be inter-connected to the electric utility grid. With this manual the PVI 3000S, PVI 4000S, PVI 5000S, and PVI 5300 can be installed and operated safely. This installation guide is used as reference for commissioning and as a guideline on how to use the inverter most effectively.
  • Page 8 600V DC maximum system voltage for the power levels of the PVI 3000S, PVI 4000S, PVI 5000S and PVI 5300 for use with 1kW to 7kW PV arrays per inverter. Data acquisition, display and communication The integrated data acquisition, display and communication capability of the PVI 3000S - PVI 5300 allows comprehensive tracking of data for understanding of system performance.
  • Page 9 PVI 3000S - PVI 5300. The maximum power processed from the PV array is automatically reduced to limit excessive inverter temperature. The PVI 3000S - PVI 5300 will only operate in parallel with the utility grid. AC grid monitoring is done by microcontrollers configured to meet the requirements of UL1741/IEEE1547. The inverter shuts down immediately if the grid goes down, or if the grid gives surges, sags, changes frequency or otherwise shows signs of instability.

    AC and DC (PV) Connections: The PVI 3000S-5300 inverters are equipped with covered holes and knockouts to fit conduit fittings that are NEC code-compliant for use with several sizes of rigid and flexible metallic or non- metallic conduit. All conduit and wiring installation is done in the wiring box. This design allows installation and wiring of the inverter to be done without opening the main inverter enclosure which should not be opened during installation.
  • Page 21 The PVI 3000S-5300 are grid connected devices, suitable for both 240V AC and 208V AC grid- connected use. For example, connection to 2 phase legs of a 208V AC, 3-phase service (where acceptable by code). No unit (PVI 3000S, 4000S, 5000S, or 5300) can be used with just a 120V AC connection.

  • Page 22: Connecting The Inverter Wiring

    A dedicated AC circuit breaker in the home or building circuit panel is required for the PV inverter. Every PVI requires a 208/240V AC rated 2–pole circuit breaker. The following is a table showing the appropriate circuit breaker for the PVI 3000S, 4000S, 5000S, and 5300 (based on number of Amps).
