ABOUT POWER OPTIMIZER
For bolts For clips
To solve mismatch issues caused by shading, dust/snow, orientation
differences, power derating differences, dual-surface cells and so on.
SUNGO OPTs can reduce power loss 3~25%.
Optimize power generation，to achieve LCOE.
Eliminate hot spot, improve system reliability, and extend operation life
of PV modules.
Reduce output voltage of PV modules, to connect more modules in each
string.
