Design Considerations
Orientation and Clearances
While the myPV CommsSafe is very compact - appropriate electrical, service, and door
swing clearances should be considered prior to determining final pad dimensions and
placement of conduit entry points. Ideally, your CommsSafe front facing swing door
panel will face north-west, away from the sun. The front facing panel door opens right to
left. Allow for full clearance to open the 24x24 in (61x61 cm) door.
All myPV CommsSafe mechanical drawings provide recommended electrical
termination cabinet conduit locations and dimensions for open door swings.

Electrical Isolation/AUX Power
There is a fuse disconnect between the auxiliary power terminated by the EPC and the
control cabinet. The CommsSafe is able to run on battery backup for 45 minutes in the
event that auxiliary power is lost. Note, the battery back up time out is adjustable.
The three phase power or 120V power should be terminated in the bottom left of the
cabinet. Refer to the Quick Start Guide for more information.
All three power supply levels of the myPV CommsSafe are rated for a control panel
SCCR level of 10KA.
Instrument Installation
Several instruments are offered and configured to best suit your monitoring needs. Wind
Sensors, POA, GHI, Albedometer, Dust IQ, Soiling, BOM, RTD BOM, and Ambient
sensors are all available to meet the needs of your project.
