Rooftop solar installations are spreading from Lahore to Karachi. Off-grid battery systems are powering homes in areas where grid reliability is low. Farms across Punjab are running DC pumps and irrigation systems around the clock.

Standard AC relays and smart switches are not designed for direct current. AC power naturally crosses zero volts 50 times per second — this zero-crossing point makes arc extinction simple and contact erosion manageable. DC current has no zero-crossing point. Arcs burn harder, last longer, and degrade switch contacts far faster in DC environments.\u003c\/p\u003e \u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eUsing an AC smart switch in a DC circuit is not just inefficient — it is dangerous.
