2.3 Product features
CPS SC100KT-O/US-480 inverter incorporates the advanced MPPT
controlling technology and variable structure modulation strategy to minimize
the energy loss.
The design with transformer has the benefit of connecting the inverter to
the low-voltage grid more conveniently.
The enclosure of inverter conforms to the NEMA 3R (IP44) protection
class, which enables the inverter to be used in the outdoor environment.
Besides, the smart DSP control, complete protection function and
advanced thermal design guarantee the inverter with high reliability.
2.4 Inverter circuit structure
The basic schematic diagram of CPS SC100KT-O/US-480 inverter is
shown in Figure 2-2. The output of PV modules first passes through DC circuit
breaker. The inverter converts DC voltage to 3-phase AC voltage. The 3-phase
AC voltage will be removed of high frequency component by the sine wave
filter, then stepped up and isolated by the low frequency transformer and go
through AC contactor, AC EMI filter, circuit breaker, at last, be fed to the LV
grid.
