3.1.2 Other environmental considerations
3.1.2.1 Consult technical data
Consult the specifications section (section 9) for additional environmental conditions
(protection rating, temperature, humidity, altitude, etc.).
3.1.2.2 Vertical wall installation
Canadian Solar inverters are typically convection cooled and must be mounted vertically
(90 +/- 5 degrees off horizontal). Units with a fan may be mounted at 0 – 90 degrees off
horizontal.

3.1 Environmental considerations
3.1.1 Select a location for the inverter
When selecting a location for the inverter, consider the following:
● The temperature of the inverter heat-sink can reach 167
⁰
F
(75C)
.
● The inverter is designed to work in an ambient temperature range between -13
⁰
F to 140
⁰
F
(-25 - 60C)
.
● If multiple inverters are installed on site, a minimum clearance of 20 inches should be kept between
each inverter and all other mounted equipment. The bottom of the inverter should be at least 20
inches above of the ground or floor (see Figure 3.1).
● The LED status indicator lights and the LCD located on the inverter's front panel should not be
blocked.
● Adequate ventilation must be present if the inverter is to be installed in a confined space.
