MPPT Zones
The SOLECTRIA XGI 1000 inverter is equipped with four separate MPPT zones. Each zone can accommodate
up to four PV strings. All positive conductors must be landed in the fuse holders on the left side of the wiring box;
all negative conductors must be landed on the right side fuse holders. Both positive and negative conductors are
fused. See Figure 3-11 for a detailed layout of the wiring compartment.
The SOLECTRIA XGI 1000 is capable of operating with all MPPT zones tracking independently (Individual
Mode) or in unison (Parallel Mode). Individual Mode provides design flexibility when dealing with different array
orientations, shading, or string sizing. Parallel mode can be used when all strings connected to the inverter are
of similar lengths. In some circumstances parallel mode may allow the designer to maximize the DC/AC ratio.
The SOLECTRIA XGI 1000 wire box must be ordered from the factory pre-configured in either Individual Mode
or Parallel Mode. This is not field configurable. SOLECTRIA XGI 1000 powerheads are field configurable using
the HMI during commissioning.
