Energy Storage Systems (ESS)

The use of energy storage systems (ESS) is on the rise—increasing the availability and reliability of alternative energy sources. ESSs are used in a variety of industries and deployment environments, many that include harsh conditions. This requires ESS design to be rugged. SiTime MEMS timing products provide excellent temperature stability and resilience to environmental stressors, making them an ideal solution for ESS.

Download Application Brief

Energy storage systems sometimes also referred to as battery energy storage systems (BESS), are devices that enable energy from renewables, like solar and wind, to be stored and then released on demand. A typical ESS consists of a battery pack, an inverter, a power optimizer, plus a battery management system (BMS) to monitor the health of the cells. 

ESS systems can be configured in four ways depending on whether they operate off grid or with a grid tie-in. The four general configurations are:

• Off-Grid: AC coupled
• Grid Tie-In: AC coupled
• Off-Grid: DC coupled
• Grid Tie-In: DC coupled

These systems need to withstand the elements as they are subjected to temperature variations, which can be extreme depending on where they are deployed. SiTime timing solutions, with temperature stability and extended temp capability, are an ideal solution whether you’re designing a BMS, an inverter, or power optimizer as shown below.

SiTime Advantages

All SiTime devices offer the following advantages over quartz crystals, which are particularly important for Industrial applications:

• Factory programmable to any frequency
• Higher reliability than quartz
• No activity dip or cold start issues
• Wide operating temp (-40°C to 105°C)
