Thermal imaging, also known as infrared imaging, is a powerful diagnostic tool in the inspection of Solar PV systems and Battery Energy Storage Systems (BESS). It captures and visualises temperature variations on a surface, allowing inspectors to identify hot spots, hot joints and irregular heat signatures that could signify electrical faults, failing components, or degraded […]

RCD Requirements for Backup Power from Solar PV Inverters
Some solar PV inverters offer a backup circuit that can be used even without the presence of batteries. This backup circuit offers the ability to power a small load, when the PV system is generating energy and when the grid is unavailable. Examples of these inverters include the following: 1. Fronius GEN24 Plus (with “PV […]
