MAT E3 Programming
IM PORT AN T :
Programming should be done by a qualified installer who is trained on programming inverter power systems. Failure to program accurate parameters for the
system could potentially cause equipment damage. Damage caused by inaccurate programming is not covered by the limited warranty for the system.

WARN I NG: Fire /Ex plosion H azard
Do not place combustible or flammable materials within 12 feet (3.7 m) of the equipment. This unit employs mechanical
relays and is not ignition-protected. Fumes or spills from flammable materials could be ignited by sparks.
WARN IN G: Pe rsonal I njury
Use safe lifting techniques and standard safety equipment when working with this equipment.
IM PORT AN T:
Clearance and access requirements may vary by location. Maintaining a 36” (91.4 cm) clear space in front of the system
for access is recommended. Consult local electric code to confirm clearance and access requirements for the specific
location.

The Inverter ON/OFF terminals are used for connecting an
external ON/OFF switch. To use this feature, the jumper
must be removed. (See Radian manual for details.)
The AUX terminals can be used to start a generator
or to control external devices.
AUX terminals are also available on the charge
controller and the FLEXnet DC. (See the charge
