PVI 3000S, 4000S, 5000S, 5300 Series Inverters 1.0 Introduction The PVI 3000S, PVI 4000S, PVI 5000S and PVI 5300 are residential/commercial single phase, gridtied 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.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters The string PV concept The use of string PV concept significantly reduces the cabling costs on a photovoltaic system. The use of strings of several PV modules in series and multiple parallel strings of PV modules has proven advantageous by delivering a high operating voltage to the inverter. This advantage results in a higher system efficiency.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters The housing and heat sink for the PVI 3000S - PVI 5300 is manufactured using an aluminium extrusion with an anti-corrosion finish. The housing is NEMA 3R compliant to be resistant to rain and snowfall. The heat sink and fan are designed in such a way that operation of the inverter is possible at ambient temperatures of -13° F (–25° C) to +131° F (+55° C) at full rated power.

PVI 3000S, 4000S, 5000S, 5300 Series Inverters 2.0 Site Preparation and Inverter Placement The inverter is comprised of a rainproof NEMA 3R industrial enclosure containing electrical and electronic components. NOTE: If the inverter is mounted outside, during the installation process and in case of rain, do not open the inverter. Criteria for device mounting: • Because the inverter is in a NEMA 3R enclosure, the inverter can be mounted outdoors.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters CAUTION: Please follow these guidelines: • The inverters weigh up to 60 lbs (27.2 kg) depending on inverter model. Be sure to use a mounting method that will safely hold this weight. Refer to Table 9.3.1 for specific weights for each inverter model. • The ambient temperature must be between –13oF and +131oF (–25oC and +55oC) for full power, and continuous operation.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters 2.1 Inverter Positioning and Mounting Correct mounting position for the inverter is vertical with back of inverter mounted to a wall. Figure 2.1.1 – PVI 3000S-4000S Dimensional Diagram Figure 2.1.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters Figure 2.1.3 – Inverter clearances WARNING: Severe injury or death could occur if the inverter mounting fails and the unit tips over or falls on a person. NOTE: The weight of the inverter will exert an added load to the wall where mounted. Be sure to verify proper load capacity of mounting surface.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters 3.0 Installation WARNING: Before installing the inverter, read all instructions and caution markings in this manual and on the inverter as well as on the photovoltaic modules. WARNING: Electrical installation shall be performed in accordance with all local electrical codes and the National Electrical Code (NEC), Canadian Electrical Code for Canada (CEC).
PVI 3000S, 4000S, 5000S, 5300 Series Inverters 3.2 Removing Inverter from Cardboard Box and Moving Inverter Into Place WARNING: The inverter may tip over if improperly moved, potentially causing damage to equipment, personal injury or death. After taking the inverter out of the cardboard box, you will find the mounting bracket in the bag behind the heatsink. First, the mounting bracket needs to be picked up from the inverter, as shown in Figure 3.2.1. Figure 3.2.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters Figure 3.2.2 – The Mounting Bracket with dimensions Use the mounting bracket as a template to mark the locations on the wall where holes should be drilled.

PVI 3000S, 4000S, 5000S, 5300 Series Inverters Once the mounting bracket is fastened to the wall, then the inverter and the wiring box can be hooked onto the mounting bracket and slipped down into place. Make sure the lower lip on the bracket hooks into the window on the back of the inverter as shown in Figure 3.2.4. Slide the mounting hooks on the inverter over the hooks on the mounting bracket.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters After the inverter is hooked properly on the bracket, secure it with screws at the bottom flange as shown in Figure 3.2.5. Figure 3.2.

PVI 3000S, 4000S, 5000S, 5300 Series Inverters Lightning and Surge Protection: The inverter is designed with certain protections against surges in voltage including certification to UL1741/IEEE1547 /CSA22.2#107.1 / FCC Part 15B (including ANSI/IEEE 62.41/62.42 as required in the NY SIR), however added protection and solid grounding provisions are important for best protection against utility surges and surges created by indirect lightning strikes.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters AC Circuit Breakers: 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).

In the parallel configuration, each inverter shall connect to its own PV array. Do not connect one PV array to more than one inverter. This will cause the inverter to function abnormally. Correct Configuration from DC Side Figure 4.3.1 Parallel configuration of inverters is done on the AC side not the DC side.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters The wiring box of the PVI 3000S-5300 inverter is designed with a pair of DC terminal blocks which support up to four (4) independent PV strings to be fused and connected in parallel in the wiring box and then fed into the inverter (or 3 fused inputs in the case of the PVI 3000S). The PVI 3000S5300 inverter is shipped with up to four (4) 15A, 600Vdc PV string fuses in the wiring box for the PV strings.
PVI 3000S, 4000S, 5000S, 5300 Series Inverters WARNING: Polarities of each DC input voltage from a PV string shall be connected correctly to the “+” (positive) and “–” (negative) terminals of a pair respectively. The DC voltage must be less than 600V in any condition. WARNING: The inverter is listed for no backfeed current into the PV array. However, the ampacity of the PV strings must be calculated when determining proper PV combiner fuse value to prevent fire hazard.
