QGateway Positioning  

The  QGateway  relies  on  solar  panels  to  charge  the  onboard  batteries.  To  ensure  adequate  power,  during 
installation, the QGateway must be oriented to maximize solar collection.  

1)  Using  a  physical  compass  or  cell  phone  compass  app,  identify  south  (for  installations  north  of  the 

equator) 

2)  Install the QGateway on the magnetic surface:  

a.  Securely grab the QGateway with (2) hands on the sides.  
b.  Gently roll the QGateway onto the magnetic surface (See Figure 13-Figure 16).  

 

WARNING: DO NOT 

attach

 the QGateway to a magnetic surface by placing the magnets straight onto 

the  surface!  The  rolling  method  described  above  is  required.  The  cumulative  magnetic  force  of  the 
mount is ~165lbs (75 kg). Failing to properly roll on the mount as described can result in personal injury 
or damage to the QGateway. 
 
WARNING: DO NOT 

detach

 the QGateway from  a  magnetic surface  by pulling straight up from the 

mounting surface! The rolling method described above is required. The cumulative magnetic force of 
the mount is ~165lbs (75 kg). Failing to properly roll off the mount as described can result in personal 
injury or damage to the QGateway. 
 

3) 

Ensure the QGateway unit’s solar panel faces south. See Figure 13 

a. 

If  the  unit  needs  to  be  repositioned,  gently  “roll”  the  magnets  off  the  surface  to  release 
connection (Figure 14 - Figure 16) 

 

4)  Verify  cellular  tower  direction  (see  Site  Preparation:  Cell  Coverage  Evaluation  for  cellular  tower 

identification)  and  ensure  that  the  cellular  antenna  is  not  pointing  directly  at  the  cellular  tower.  This 
scenario only occurs in a situation where the cellular tower is located directly north or south from the 
QGateway. This will require a reevaluation of the QGateway positioning to allow for maximized solar 
collection and cellular range. Consult Qualitrol if assistance is needed.
