GRIDCON® ACF ESS

GREAT COMBINATION – ACTIVE FILTER AND ENERGY STORAGE.

Your benefits at
a glance

  • Optimization of earnings from PV, CHP, wind turbines in own grid
  • Back-up power supply should the grid fail
  • Adaptation of grid supply to schedules with renewable energy generation
  • Stabilization of voltage in distribution grids with a high share of renewable energies
  • Integration of renewable energy generators in tiny grids to reduce operating costs

Product description

GRIDCON® ACF ESS is based on an inverter architecture which has proved itself in an industrial Environment and has now had an energy storage added to it.

  • Combination of reactive power compensation, active filter, and energy storage in one system
  • Modular concept for individual, applicationspecific adaptation and retrofitting
  • Connection voltage of up to 480 V (+/-10%)
  • Output range of 400 kW in one system (more possible in integrated network)
  • Energy storage of up to 2.4 MWh in one system (more possible in integrated network)
  • Existing ACF systems can be retrofitted with an energy storage system
  • Energy storages using different technologies and from different manufacturers can be linked to suit the application
  • High levels of safety and availability thanks to an extensive protective concept at inverter level and constant modularity
