Mechanical Installation

Inverter Environment
The SOLECTRIA PVI 25TL-208, PVI 50TL-480, AND PVI 60TL-480 inverters are equipped with a NEMA Type 4X rated,
Polyester Powder-Coated Aluminum enclosure suitable for outdoor installation in many different climates. Select
the mounting location appropriately taking into consideration snow, wind, rain, direct sun, pests, vegetation
growth, and any other local environmental conditions. To increase its life span, it is recommended that the inverter
be installed out of direct sunlight; for example, under a shade structure, on a north facing building wall, or on north
facing racking. Never install inverters in areas that are prone to flooding, standing water, prolonged snow coverage,
or near explosive or flammable materials.
Explosion or Fire Hazard: Electrical devices can cause fires. Never install in areas prone to explosive gasses,
liquids, or in close proximity to flammable materials.
Maintain NEMA Type 4X Rating: It is the responsibility of the installer to maintain the NEMA Type 4X rating of
the enclosure. Failure to maintain the NEMA Type 4X rating will void the warranty.
Improper Installation Will Void Warranty: Never install the inverter in areas that are prone to flooding, standing
water, or prolonged snow coverage. It is important to ensure the cooling fans and exhausts remain clear from
obstructions at all times.
Temperature Derating: The SOLECTRIA PVI 25TL-208, PVI 50TL-480, and PVI 60TL-480 inverters are rated for a
wide range of operating temperatures. When installed in environments that may experience ambient
