Full range of devices for BESS control

Power converters, application controllers – and everything else you need



DEIF offers a complete range of products, from controllers and converters to commodity accessories, that helps you build customised and scalable BESS solutions for any application.

  • Our iE 150 and iE 250 controllers give you full battery control with a wide range of BMS and PCS brands, allowing you to control your BESS efficiently – and interface with generators, solar panels, and the mains grid. And our PPC software (which runs on the iE 250) lets you provide energy trading and ancillary services.
  • The compact, efficient, and low-noise iE Convert power converter range lets you seamlessly convert energy between AC and DC, and between voltages and frequencies, in any mobile or stationary solution – even at utility scale.
  • The TDU and AGI 400 series of displays help your users visualise and control every parameter of your BESS assets, even in direct sunlight and extreme weather.
  • With our full range of switchboard components, you can source all the devices you need from a single supplier to get the parts for your BESS solution, from battery chargers and DC supplies to current transformers and shunt resistors.
  • The Insight remote monitoring service gives you easy remote asset management on a subscription basis, and it can coexist with your proprietary IoT connectivity solutions if needed.
