INSTRUCTION:
The default Working Mode of the inverter is Independent Mode (3
MPPTs). The Working Mode may be configured to operate in Parallel
Mode (1 MPPT) only as an exception.
Every effort should be made to design within one string count
difference for each of the three MPPTs to avoid unnecessary power
clipping. When the input power for one MPPT zone exceeds the
individual maximum allowed (Max PV Power), however the combined
input power is below the inverter maximum input specifications, the
inverter may be set to operate in Parallel Mode (1 MPPT). In this
mode, all strings should be the same module type (Mfg and ratings),
same series module count, and same module orientation (tilt and
azimuth).
Parallel Mode is not preferred since it affects the sensitivity of
the AFCI and may increases the possibility of false DC Arc-Fault
trips. Setting to Parallel Mode must be approved in advance by
CPS and must be performed by a CPS Service Technician.
