Cat offers an Energy Time Shift and a Grid Stability Energy Storage Module. Both modules are scalable, robust, ready to deploy solutions. The ESS can integrate with solar or other renewable energy sources to store energy from overproduction for use when the renewable source is not available. Cat ESS can also provide temporary backup power to facilities in the event of a power outage.
Energy Time Shift Module contains lithium-ion batteries, Cat bi-directional inverters, color HMI touchscreen, remote communications, HVAC system, lighting, convenience receptacles and a fire suppression system. The batteries provide good energy density, high discharge/recharge efficiency and high cycle life.
Grid Stability Module contains the same equipment as the Energy Time Shift module, plus ultra-capacitors for short duration, high power output to minimize the discharging of the lithium-ion batteries and support momentary load surges.
