11 kW Bidirectional Modular Power Unit

Ref. BMPU-R2-500-32

Designed for smart grid (V2G, V2H, V2L) applications, BMPU-R2 is a modular grid-tied power supply capable of bidirectional conversion between AC (grid) and DC (EV battery). Its innovative 4-phases design enables operation in three-phase 16A (with or without neutral) or single phase 32A. This module supports 3 modes: G2V (charging battery from grid), V2G (discharging battery into the grid), V2L (creating AC grid using battery power).

BMPU-R2 is the latest generation of our greatly renowned BMPU series of V2G converters, deployed as part of the Smart Fossil Free island (with Renault at Porto Santo).

Our BMPU-R2 technology has been awarded “Seal of Excellence” by European Council with 4 patents filings under the IPA4SME program.
