2 Installation
WARNING:
Before installing the PVI 3000-5300, read all instructions and caution markings in this manual
and on the PVI 3000-5300 as well as on the photovoltaic modules.
WARNING:
Electrical installation shall be done in accordance with all local electrical codes and the National
Electrical Code (NEC), ANSI/NFPA 70.
WARNING:
Connecting the PVI 3000-5300 to the electric utility grid must only be done after receiving prior
approval from the utility company and installation completed only by qualified personnel/licensed
electrician(s).
2.1 Checking for Shipping Damage
The PVI 3000/4000/5000/5300 inverters are thoroughly checked and tested rigorously before they are shipped. Even though
they are delivered in a rugged, heavy cardboard box, the inverters can be damaged in shipping.
Please inspect the inverter thoroughly after it is delivered. If any damage is seen please immediately notify the shipping
company. If there is any question about potential shipping damage, contact Solectria Renewables. A photo of the damage
may be helpful.
Do not accept unit if visibly damaged or note visible damage when signing shipping company receipt. Report damage
immediately to the shipping company. Do not remove the unit from packaging. If it is determined that the unit must be
returned, an RMA# must be obtained from Solectria Renewables.
2.2 Inverter Mounting
The PVI 3000/4000/5000/5300 inverter is made up of a sealed NEMA 3 corrosion resistant, painted aluminum enclosure
containing all electrical and electronic components.
NOTE:
If the PVI 3000/4000/5000/5300 is mounted outside, make sure the mounting & wiring is completed,
at least to the AC and DC disconnects or junction box(es) in case of rain during the installation process (for
example overnight rain). Since the AC and DC connections are
wired to the wiring box, disconnects and or
junction box(es) only, there is no need to open the main inverter enclosure during hook-up. The inverter
enclosure is factory sealed and must NOT be opened at any time in the field as this will void the warranty.
Notes regarding mounting and placement of the inverter
Criteria for device mounting:
Because the inverter is in a NEMA3 enclosure, the inverter can be mounted outdoors.
The very longest life for the inverter can be achieved by mounting it in a clean, dry and cool location even given the unit’s
robust construction and design for efficient cooling. It is recommended to keep the unit out of direct rain. Protection from
a roof overhang, awning is better if the unit cannot be mounted indoors or in a shed, garage or basement.
For optimal electrical efficiency, use the shortest possible AC and DC wires and use the maximum allowable wire size.
(Depending on which model inverter, 8-10AWG minimum (#6 maximum) is recommended for all connections, both AC
and DC.)
Avoid installation in close proximity to people or animals, as there is a small amount of high-frequency switching noise.
Install the inverter in an accessible location following NEC and local codes. Note NEC requirements for clearances and
proximity to other equipment and building walls.
Although not required, installation at eye-height allows easy reading of the indicator LEDs and the LCD display.
