The REFUstore battery inverter is based on the new inverter platform from REFU. This inverter is specifically designed for all high voltage batteries. With a rated power of 88 kW at 400V, it is perfectly suited for commercial behind-themeter applications such as self-consumption optimization or peak-shaving.

Future Proof, Integration with Storage and PV Systems
The AC-coupled REFUstore can be easily integrated with existing PV systems. The highly modular solution allows it to be used in systems from 50 kW up to MWs in size to meet the demands of both energy and power applications.

Storage Solution Inverter with EMS ready for your Battery System
The REFUcontrol BC-10 EMS is our solution, completing our REFU inverter that you can build your own Battery System. It controls for self-consumption, peak shaving and time-controlled charging. It comes with an data edge controller automatically connected to a cloud-based portal – at no extra usage fee. Your battery and usage data is visualized both on a web browser and on an APP, equipped with a live view modus. It has an API for data export and User Management integrated. Measurement via energy meter through transducer measurement up to 400 A (276 kW).

Maximum Performance
The REFUstore is highly efficient over a wide range of operation maximizing return on investment (max. 98,4% efficiency). With fast response times, the inverter achieves high control performance, making it suitable for time-critical applications. Transformer-less with IP54 robust housing.

2nd Life Application
With a min. DC voltage of 280V, the REFUstore 50K can be used in 2nd life battery applications with ease to support the grid for applications such as frequency regulation, optimizing self-consumption, peak shaving etc.

Design Flexibility
WIt is specifically designed for all different types of high voltage batteries. It allows different communication protocols like Modbus RTU/TCP and Sunspec/MESA. The higher flexibility in system design reduces BOS costs drastically.

Best Serviceability, by simple 2-box field installation system
The ConnectionBox and the PowerUnit are separated. The ConnectionBox is first installed and wired, while the PowerUnit is added shortly before commissioning. The weight is therefore reduced at mimium to 25 kg. This reduces the amount of personnel required for installation and thereby optimizing your investment and project cash flow. It also offers easiest serviceability – the PowerUnit can be quickly detached from the ConnectionBox for trouble shooting and measurements – without disconnecting the power cables on the DC or AC sides.

Connectivity
The inverter can be commissioned via the REFUset app (available for iOS and Android) which connects seamlessly via Bluetooth® to the inverter. The integrated, fail-safe Ethernet daisy chain (alternatively RS485) allows cost efficient high-speed monitoring without special accessories. Each inverter can be individually connected to the REFUlog portal for remote monitoring, configuration, and updates. The REFUlog monitoring portal comes for free with each inverter during the warranty period of 5 years.

Storage Business Models in Commercial & Industry

  • REFUstore inverter and REFUcontrol allow you to build your business model, no matter if it is to
  • REDUCE ENERGY COST by Peak Shaving or balance load for extended EV-Charging in industrial places
  • SELF-CONSUMPTION OPTIMIZATION & OPERATIONAL SAFETY by emergency power capability or
  • DEPLOYMENT OF GRID SERVICES by marketing and provision of primary control power
