How We Lost Our Website — And Built It Back
In April 2026 a ransomware attack encrypted our entire website. We chose not to pay, rebuilt from scratch on Astro and Supabase, and recovered most of seven years of content (everything since 2019) from the Wayback Machine.
How to check the Earthing of Inverter/UPS step by step guide
Earthing, also known as grounding, is absolutely crucial for the safe and efficient operation of Inverter/UPS systems. Here’s a breakdown of its importance: 1. Safety: Protection Against Electric Shock: In the event of a fault, such as a live wire coming into contact with the metal casing of the UPS or connected equipment, a […]
Earthing is a critical safety feature in Uninterruptible Power Supply (UPS) systems
Earthing (or grounding) is a critical safety feature in Uninterruptible Power Supply (UPS) systems. It ensures the safe operation of the UPS and connected devices by providing a path for fault currents to dissipate into the ground, preventing electric shock, equipment damage, and fire hazards. The earthing connection in the UPS back panel is a key part of this […]
