AC bidirectional power module.

 

Power Modules 11 KW BMPU

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).

As a high-performance bidirectional power module, the BMPU-R2 has earned the European Council’s “Seal of Excellence,” with four patent filings under the IPA4SME program — a testament to its innovation and impact in the field of smart mobility and renewable integration.

PCS-100 Power Module

Designed for Battery Energy Storage Systems (BESS), PCS-100 is a high-efficiency bidirectional power module rated at 100 kW, operating as a string inverter between the AC grid and DC battery. Its modular design allows parallel operation and can be used as a part of a high power system reaching up to several megawatts. The converter supports two modes of operation: On-Grid (charging and discharging the battery to the grid) and Off-Grid (creating AC grid from battery power).
