What REConvert does

REConvert B.V. is a Nieuwegein-based power electronics development company founded in 2018, focused on bidirectional inverter and grid-interface technology for the renewable energy and battery energy storage system (BESS) market. Its core hardware product, the InREC-36, is a 30kW bidirectional battery inverter designed as a modular OEM building block that scales from 30kW to 1MW via three independent high-voltage DC inputs and Modbus RTU / CAN-CCP communications. The portfolio is extended by the ACS-IoT control device (autonomous grid management, export/import control, fast grid synchronization, remote diagnostics), the Backup Trio backup-power add-on, and a real-time monitoring stack using MQTT, InfluxDB, and Grafana. Historical residential products include the Battery Flex AC1 and Battery Flex Backup Solo developed in collaboration with Solarwatt.

The company monetizes through OEM hardware sales, licensing of its power-electronics technology, and engineering services spanning hardware/firmware development, testing, and certification. It serves system integrators and commercial & industrial end-customers in Europe (primarily the Netherlands) with prior operating experience in the US market, and is expanding into the SME/light-industrial UPS segment through the EFRO-subsidized Pulse project co-developed with Kiwatt. Certifications to VDE-AR-N 4105/4110, IEC 62109, and IEC/EN 60529, plus Netbeheer Nederland Type A approval, underpin its credibility with European grid-tied BESS integrators. After a 2022 acquisition by Solarwatt GmbH and subsequent separation in October 2024, REConvert resumed independent operation under Managing Director Arno van Zwam, refocusing on the C&I segment as an OEM manufacturer.

Core offering

REConvert designs, develops, and manufactures bidirectional power electronics for renewable energy applications, with its core offering being the InREC-36 30kW bi-directional inverter used as a building block in commercial Battery Energy Storage Systems scalable from 30kW to 1MW. The company also supplies IoT-based grid sensors (ACS-IoT), backup power solutions (Backup Trio, Battery Flex Backup Solo), residential storage power electronics (Battery Flex AC1), and provides engineering services in hardware and firmware development, testing, and certification.

Product overview

REConvert operates as both a product company and an engineering services provider, offering power electronics solutions across two main segments. The C&I portfolio centers on the InREC-36 30kW bi-directional inverter, which is the core building block for commercial Battery Energy Storage Systems up to 1MW, complemented by the ACS-IoT (AC Sensor) for IoT-connected energy management and seamless grid/backup switching, and the Backup Trio for automated backup power during grid outages. The residential segment is anchored by the Battery Flex AC1 (which REConvert designed the AC-DC conversion technology for), with the Battery Flex Backup Solo providing whole-house emergency power switching. All products share a common monitoring infrastructure using MQTT, InfluxDB, and Grafana. REConvert also develops custom OEM products and provides engineering services in power electronics, hardware/firmware development, and system certification.
