Inside a Solar Hybrid PCU: MPPT Internal Circuitry Explained by its Designer
What's really inside a solar hybrid PCU? I have been designing Power Conditioning Units since 2011, when my R&D team built one of India's first integrated solar PCU circuits — an MPPT charge controller, grid charger, pure sine wave inverter, isolation transformer and…
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 […]

How the Su-vastika 5.5 kVA Solar Hybrid PCU works: MPPT solar charging (up to 30% more than PWM), solar-first priority logic, lithium BMS integration, Bluetooth/Wi-Fi app, over-the-air updates, digital warranty and BIS certification.
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 […]
