Power Quality
Power Quality refers to how reliable and stable electrical power is when it's delivered to devices and equipment. Think of it like water pressure in your home - you want it to be consistent, not too high or too low. In the energy storage industry, Power Quality involves making sure electrical systems provide clean, consistent power without interruptions, surges, or other problems that could damage equipment or cause outages. This is becoming increasingly important as more businesses rely on sensitive electronic equipment and as renewable energy sources become more common.
