SOLAR ENERGY HARVESTING
Innovating a Brighter Future: EfficientlyTransforming Sunlight into Sustainable Power

Sustainable power generation
technologies like solar energy harvesting
are playing an important role in the need

Our products can precisely sense both direct (DC) andalternating (AC) currents up to 5 MHz of bandwidth without
any bulky components such as transformers.

for environmentally friendly energy

With wide current measurement options ranging from 0 toproduction. These technologies lower±400 A, there is an Allegro sensor to meet the application

dependence on fossil fuels that are thesource of pollution and carbon emissions

need in any power-rated solar system. Sensor options areavailable in 1% total error with optional integrated featuresthat include overcurrent alerts.

related to global climate change.

Allegro’s current sensor ICs are ideal for use with solar
applications, which include electronic subsystems like solarcombiner boxes, DC/DC converters for maximum power
point tracking (MPPT), and DC-AC inverters. Allegro’s
current sensors offer easy-to-use, turnkey solutions
packaged in small standard and custom footprints. Thesesensors deliver accuracy and high voltage isolation up to4.8 kV without the need for external components.  

This results in increased design-in flexibility for customers
while also optimizing the size and performance of theirprinted circuit board (PCB) design.
