DC Screen Battery: Why It Determines the Bottom Line of Backup Power Reliability

Aug , 13 2026

Quick Answer A DC screen battery is the key component that determines whether a DC power system can continue supporting critical loads during an unexpected power failure. During normal operation, the charging module and monitoring system keep the DC system running, making the battery easy to overlook. However, when AC power suddenly disappears, the battery must immediately take over and provide st...

Why Lead Acid Batteries Require Regular Equalization Charging During Long-Term Float Operation

Aug , 14 2026

For critical backup power applications such as UPS systems, telecom networks, substations, and industrial energy storage systems, lead acid batteries are often operated under long-term float charging conditions to maintain standby power availability. However, continuous float charging alone cannot completely eliminate the differences between individual battery cells. Over time, these small differe...

UPS Suddenly Transfers to Bypass Mode: Causes, Risks, and Troubleshooting Guide

Aug , 25 2026

Quick Answer When a UPS suddenly transfers to bypass mode, it does not always mean the UPS has failed. In many cases, the transfer is a protection action caused by conditions such as overload, inverter abnormality, or maintenance operation. However, bypass mode is different from normal inverter operation. Although the load may continue running, the UPS may no longer provide the same level of volta...

Harmonics in Power Systems: Why Normal Operation Does Not Mean the System Is Healthy

Sep , 08 2026

Quick Answer The biggest challenge with harmonics is that they usually do not cause immediate equipment failure. A power system may continue operating normally, while distorted current gradually increases losses, temperature rise, and stress on the entire power distribution system. For systems with rectifiers, UPS systems, battery chargers, variable frequency drives, and switching power supplies, ...

Can I Replace My Lead-Acid Battery with a Lithium One

Sep , 12 2026

For decades, lead-acid batteries have been widely used in UPS backup systems, solar energy storage, RVs, marine applications, and off-grid power systems. However, traditional lead-acid batteries often come with limitations such as heavy weight, shorter service life, regular maintenance requirements, and reduced performance under deep-cycle conditions. With the development of lithium technol...
