Customer ServiceThere are two switching times for energy storage inverters. One is charging and discharging switching. Large energy storage countercurrent should be able to quickly switch operating states. The requirement typically mandates maintaining a grid-connected charging state and a grid-connected discharge state, each at 90% rated power.
Switching time/transfer time in a UPS (uninterruptible power supply) is the time it takes to switch from the utility to the battery power supply. It is typically measured in milliseconds. The switching time is crucial because it determines how long the connected equipment will continue to operate without interruption when there is a power outage.
Mains to Inverter Mode: As the Power goes off, there is a switching time from Mains to Inverter mode, which is generally higher than the Inverter to Mains Mode. For the Power Electronics designer, handling this is challenging as the MOSFET or IGBT can burn if this is maintained at a very low level.
Uninterrupted Power with fast switching time in Inverter/UPS is the real challenge to solve. The switching time of a UPS is typically specified in the product documentation. It is essential to choose a UPS with a switching time that is short enough to meet the needs of the connected equipment.
Short switching time is the key to a smooth transition from utility to battery power and battery to utility power. Switching time/transfer time in a UPS (uninterruptible power supply) is the time it takes to switch from the utility to the battery power supply. It is typically measured in milliseconds.
The switching time for the former must not exceed 200ms, while for the latter, it must not exceed 100ms during transitions between grid-connected and off-grid modes. Energy storage converters mainly have two working modes: grid-connected and off-grid.
