A solar inverter converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It allows to the use of ordinary AC-powered equipment with solar power. Solar inverters may →

A current transformer (CT) is used for measurement of alternating electric currents. The most common design of CT consists of a length of wire wrapped many times around a silicon steel ring passed ‘around’ the circuit being measured. Current transformers are used extensively for measuring current and monitoring the operation of the power grid. The →
A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. A fluorescent lamps are widely used because they convert electrical energy into useful light much more efficiently than incandescent lamps (The luminous efficacy can exceed 100 lumens per watt). They are widely used in →
