FlexGrid = Vehicle to Grid + Direct Solar Charging + Home Energy Storage

Hardware samples for commercial testing available in August 2020

Since 2009 Power Research Electronics b.v. (PRE Power Developers) is a well-known Charger Module supplier for OEM (charger / renewable energy solution) companies.
PRE does not offer complete solutions to consumers.

More and more companies, consumers and energy network operators see the advantages of Vehicle to Grid (V2G) and direct solar charging. Quick and efficient charging combined with a lower energy bill sounds like an interesting proposition as well. Even though this technology is in full development, PRE is already working on the next step: FlexGrid. FlexGrid adds Home Energy Storage (HES) to the concept. It will enable a whole new way of ‘home charging’.

PRE is now finalizing the first version of the hardware for the FlexGrid multiport converter (10kW V2G fast charger + solar inverter + Home Energy Storage). Discover FlexGrid!

FlexGrid, a DC grid with unprecedented possibilities
The concept of FlexGrid is that we connect the decentralized generation and storage devices working on DC (photovoltaic cells, energy storage and electric vehicles). Connecting DC sources and storage via a DC network lowers investment costs and increases efficiency. FlexGrid brings new opportunities for the built environment!








Options (combinations of these options are also possible):
Solar to Vehicle / Grid / Home Energy Storage
Home Energy Storage to Vehicle / Grid
Vehicle to Grid / Home Energy Storage
Grid to Vehicle / Home Energy Storage

PRE Multiport Converter, electric heart of FlexGrid
The electric heart of the FlexGrid concept is the PRE Multiport Converter with a multi-directional power flow. The Multiport technology enables us to charge both the EV and the home battery with solar energy and also controls the energy between the batteries. This creates a whole new way of ‘home charging’. For example: with less sunny days you can charge the home battery with your EV or vice versa. The converter is acting as the electric heart of the DC smart home. The FlexGrid concept offers also opportunities for offgrid solutions.
Flexgrid Consortium
PRE Power Developers participates in the FLEXGRID Research Project (a TKI Urban Energy Project), together with Alfen, Stedin and Delft University of Technology. PRE was responsible for the development of the multiport converter (an in kind investment).
