Higher reliability
Seperated junction boxes design,
lower junction box failure rate
Higher output
0 to
+5W
0 to +5W positive tolerance
48
48-hour response service
Improved ribbon layout and cable length,
enhanced Fill Factor, increase power output
up to 1% by reducing power loss.
More safety
Better diode connection from SMD bypass
diode.
Lower junction box temperature
Fast heat dissipation, lower diode operating
temperature, long diode life circle.
