FREEMAQ DC/DC - BI-DIRECTIONAL DC/DC CONVERTER

The new Power Electronics Freemaq DC/DC is a bi-directional DC converter designed to maximize the benefits of the large-scale solar plants with a solar-plus-storage approach, offering a cutting edge technology product that is able to reduce the CAPEX of PV installations coupled with energy storage systems, avoiding the installation of an additional station with a dedicated MV transformer.

Following the Power Electronics philosophy, the Freemaq DC/DC is a modular outdoor solution available from 525kW to 4800kW, fully compatible with different battery technologies and manufacturers, with a voltage range up to 1500Vdc and the highest efficiency in the market. This product has been designed to be easily integrated with a Freesun inverter in new or already installed PV power plants, being the most cost-competitive solution for battery storage systems paired with PV installations.

With a DC-coupled energy storage system, the excess energy from the PV plant can be stored in the Battery Energy Storage System (BESS) and then delivered when needed. It also realises maximum revenues from the PV generator by charging the battery storage system when there is an inverter power curtailment.
