1.0: Overview
1.1 Inverter for Grid-Tied PV Systems
The PVI 50/60TL inverter is suitable for use on commercial and utility-scale rooftop,
carport and ground mount grid-tied PV systems. A system is generally made up of PV
modules, DC power distribution equipment, PV inverter and AC power distribution
equipment (Figure 1.1). The inverter converts 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.
