2. Planning 2.1 Selecting a Location for the Inverter and Integrated AC/DC Disconnect When choosing a location for the inverter/disconnect unit, consider the following criteria: • • • • The unit is suitable for both indoor and outdoor installation; the inverter and disconnect enclosures have a NEMA 3R rating. The optimum location of the unit is outside, shielded from direct exposure to sunlight (i.e. not on the south facing side of the building). The heat sink temperature can exceed 158°F (70°C).
The large bracket: • Has two top screw holes at either end of the large bracket, 16” (40.6 cm) apart which are designed to match standard stud spacing. Refer to Figure 3-2. The inverter also has an internal mounting screw. Refer to Figure 2-1 for the location of this screw. ! ! WARNING Before drilling holes to mount the inverter, verify that there are no electrical wires or plumbing in the area.
3. Installation 3.1 Mounting and Anchoring the Inverter and Integrated AC/DC Disconnect After you have determined a suitable location for the inverter/disconnect unit, the next step is anchoring the bracket to the wall stud(s). Models PVP1100, PVP2000, PVP2500, PVP2800, PVP3000 and PVP3500 1. Locate a wall stud in the desired location and align the mounting bracket or paper mounting template with the vertical row of screw holes over it for a single-stud mount.
6. Locate the inverter mounting hole below the power board (see Figure 3-3). Insert the mounting screw through the inverter and tighten securely. Models PVP4600, PVP4800 and PVP5200 1. Locate the wall studs in the desired location and align the mounting bracket or paper mounting template over the studs. Mark the mounting holes. Ensure that locations A and B in the following figure are aligned over two wall studs. 2. VERIFY THE BRACKET IS LEVEL. Ensure points A and B are aligned with the wall studs.

Avant de mettre l’onduleur sous tension, s’assurer que les panneaux avant de l’onduleur et du dispositif de déconnexion sont adéquatement fermés. WARNING ! The heat sink can reach temperatures in excess of 158ºF (70ºC). Do not touch the heat sink when in use, and do not place anything on top of the heat sink.
! AVERTISSEMENT Avant de mettre l’onduleur et le dispositif de déconnexion CA/CC sous tension, s’assurer que le panneau avant est adéquatement fermé et que les vis du couvercle sont vissées. The green LED should illuminate. Locate the LEDs in the upper left hand corner of the inverter’s display. Verify that the red and green LED lights are illuminated. • • If the red LED is not illuminated or is blinking, refer to Chapter 6, Troubleshooting on page 33.
PV Grid-tied Residential Inverter and Integrated AC/DC Disconnect Installation and Operation Manual Red LED is illuminated when: • The PV array voltage is not within required operating limits, such as: • At sunset, when the inverter turns off for the night. • When clouds reduce the amount of available sunlight or when portions of the PV array are covered with debris. • • Any time the DC output from the PV array drops below the inverter’s minimum DC operating voltage, the inverter turns off.
Screen 1 Screen 2 Screen 3 Figure 5-2 Running Screens If a fault occurs, the display also provides a corresponding fault code. Refer to Chapter 6, Troubleshooting on page 33 for additional information.
6. Troubleshooting The inverter provides two indicator lights in the form of Light Emitting Diodes, or LEDs. The LEDs are the primary indicators of the system status: O.K., Sleep or Faulted. The LEDs are located above the inverter display in the upper left hand corner on the front lid. 6.1 LED Status • • • The light on the left is a red LED and is the primary indicator of system stand-by or fault condition. A solid red LED and a blank screen indicates the system is in normal sleep or stand-by mode.
3. A less likely cause is limited to multiple inverter installations, when the positive and negative array strings are crossed. Crossed wires occur when a positive or negative conductor from array 1 is connected with wires in array 2. An example is if inverter A has the positive conductor from array 1 and the negative conductor from array 2 connected. 4. If the fuse is open, then a ground fault condition exists. • Check the DC voltage between the grounded terminal of the array and earth ground.
