Efficiency with usability: ABB's all new string inverter for photovoltaic systems

摘要

JUKKA NURMI - The worries of global warming and soaring oil and gas prices mean the utilization of renewable energy sources looks set to increase to meet growing global energy demands. The planet has always received generous amounts of one source of renewable energy, sun rays. The simplest method of harnessing solar energy is through the use of photovoltaic cells. These cells produce direct current (DC) which needs to be converted into alternating current (AC). This conversion is carried out using an inverter, and ABB string inverters are designed for photovoltaic systems installed primarily on residential and small- to medium-sized commercial buildings. The new inverter series now includes built-in protection functions, which reduce the need for costly and space-consuming external protection devices and larger enclosures.
