What are the different single-phase transformerless PV inverter configurations?
A transformerless PV inverter has no galvanic isolation between the input and the output, leading to current leakage problems. Parasitic capacitance plays a crucial role in the circulation of leakage current. Several types of transformerless PV inverter configurations can address this issue. This FAQ discusses why parasitic capacitance matters and the four commonly used configurations […]

Edison’s revenge? High-power DC gets another chance
DC-based power transmission lost out to AC, but DC is making a comeback. Many things we now use as basic knowledge were not fully understood in the early days of electricity and power in the late 1800s/early 1900s. Still, one thing was grasped: ohmic losses (often called IR or resistive losses) in power-transmission lines were […]
