2.1 Inverter for grid-tied PV systems
CPS SC14KTL-DO/US-208 inverter is suitable for use with various
commercial rooftop systems and distributed power station systems. Normally,
the system mainly consists of PV modules, DC power distribution equipments,
PV inverter and AC power distribution equipments (Figure 2-1). The inverter
converts the DC from PV modules to AC with the same frequency and phase
as the AC grid. All or part of the AC power is supplied to local loads, and the
surplus power is supplied to the electricity grid.

2.2 Product features
The two-MPPT design has the benefit of increasing the power generating
efficiency of the whole PV system. The inverter has 2 MPPTs, so a separate
array can be controlled by an independent Maximum Power Point Tracking
(MPPT) control circuit. This means that the two arrays can be installed in
different positions and orientations.
The transformerless design of inverter with the benefit of small size, light
weight, high power density, flexible installation and convenient maintenance
provides the best cost performance for the whole PV system.
