ABB launches a new range of Energy Storage Inverters (ESI
ABB''s new ESI range of bi-directional inverters is a one stop solution for energy storage needs and power quality problems. The ESI range can be used with different types of battery technology, and can be used in LV applications as well as MV applications by connecting through a step-up transformer.
The Solis S5-EH1P3K-L is a 3.0kW hybrid inverter, which is ideal for residential energy storage systems. Compatible with both lithium and lead-acid batteries, this highly efficient inverter offers uninterrupted power supply (20ms reaction) and a back-up supply to support more critical loads.
Inverters typically have an ability to limit maximum output power via a settable parameter or via a firmware change, the latter typically requiring the intervention of the manufacturer.
Among them, when the speed of the motor is very low, the power supply voltage of the inverter will reach the minimum voltage of the DC/DC converter, which is the rated voltage of the battery. When the motor speed gradually increases, the inverter supply voltage will increase accordingly.
Energy Storage Inverter - Applications • Inverter must be compatible with energy storage device • Inverter often tightly integrated with energy storage device • Application Topologies – On-line systems – Switching systems • "Mature" Systems – Small Systems <2kW – high volume production • Modified sine wave output
