How to solve the problem of EPS (Emergency Power Standby) function not working

EPS inoperability can be caused by external conditions insufficient power from the storage power supply and internal malfunctions. If your power supply is experiencing any of the following problems, follow the steps in this article to troubleshoot and resolve the usage issue.

Phenomenon: EPS (Emergency Power Standby) function cannot be enabled

Please follow the steps below to deal with the output problem

Step 1: Check the charging (mains) input terminal

Check whether there is a power failure at the charging terminal; EPS is based on utility power, and EPS is activated only when the utility power is cut off, and EPS function cannot be activated when the power grid is not cut off.

Step 2: Check the energy storage power display

Check the energy storage display to confirm the power level. If the internal battery of the energy storage power supply is low, it will not be able to start when there is a utility power outage (switching to the internal battery power supply of the energy storage power supply after a power outage will not be able to start if the battery is low). If the input side (power grid) blackouts, the power is sufficient to meet the EPS operating conditions, and can not start for internal failure.
