Controller Location Selection

The SubDrive Solar controller is intended for operation in ambient temperatures up to 122 °F
(50 °C). The following recommendations will help in the selection of the proper location for the
SubDrive Solar controller (Figure 4):
CAUTION: When using an alternate AC power source, the ambient temperature is limited to 104 °F
(40 °C) for full power delivery.
1. The unit should be mounted on a sturdy supporting structure such as a wall or supporting post.
Please take into account the weight of the unit.
2. The electronics inside the SubDrive Solar are air-cooled. As a result, there should be at least
45.7 cm (18 inches) both above and below to allow for air flow and proper cooling. If the
SubDrive Solar is mounted under the PV solar array, make sure that it is at least 45.7 cm
(18 inches) beneath the array.
3. The SubDrive Solar should be mounted with the wiring end oriented downward. The
controller should not be placed in direct sunlight. Placing the controller in direct sunlight
or high ambient temperatures could result in reduced performance due to temperature foldback
protection. For optimum performance, maximize the shading of the controller.
Additional Considerations for NEMA 3 (IP55) Enclosures
To ensure maximum weather protection, the unit must be mounted vertically with the cover properly
aligned and secured with all lid screws. Strain relief fittings, or IP55 rated liquid-tight conduit fittings,
should be used to bring the wires inside the enclosure.
