Rectifier & Inverter in one box built on HE technology from the Flatpack2 HE rectifier family the Rectiverter 230/1500 48/1200 provides backed up power for 230 VAC loads with minimum losses and footprint. It is a 3 port device capable of charging the 48V battery and simultaneously provides power for the AC and DC loads. During mains outage the Rectiverter feeds AC loads using energy stored in the battery.

Flatpack S Rectifiers

The Flatpack S combines High Efficiency and an extremely compact and short casing with build in Sil 3 protection. With only 210 mm long modules it fits into most applications in the shallow cabinets. Complete solutions are available in compact packages and there is flexibility to meet higher power demands in tight spaces. 

Flatpack 2 Rectifiers

Since setting the new standard for rectifier efficiency, the Flatpack2 HE family is now available in a variety of voltages and power ratings, all with superior efficiency up to 96.5%. With more than 4 billion in-field operating hours and a proven cumulative field MTBF of more than 1,9 million hours, Flatpack 2 HE is the only HE (High Efficiency) rectifier with a proven track record.


Our inverters include advanced switching technology with digital control.  The utilisation of this technology results in a very high power density and low weight. With a state-of-the-art control solution it provides an excellent functionality and several protection features.

Monitoring and Control

We have a full range of monitoring and control systems all including remote monitoring, battery management systems and programmable alerts and alarms. We have remote server based management software systems too, tailored to your requirements.
