This document is a product manual for ABB PVS-100/120-TL solar inverters, specifically the "B version" models with power outputs ranging from 100 to 120 kW. It provides essential information for qualified technicians regarding the installation, operation, and maintenance of the equipment.
The PVS-100/120-TL is a string inverter designed to convert direct current (DC) supplied by a photovoltaic (PV) generator into alternating current (AC) suitable for feeding into a public distribution grid. It features a two-box configuration, separating the power module from the wiring box, and is a transformerless inverter, which contributes to its high conversion efficiency. The internal circuitry uses a double-stage conversion process, consisting of a DC/DC input converter (booster) and a DC-AC output inverter, both operating at high switching frequencies. The inverter is controlled by two independent Digital Signal Processors (DSPs) and a central microprocessor for operation and protection management.
