Solution highlights
Why choose Resacs
Extra safety
Temperature monitoring with automatic customer notification outside the 5–30 °C range. At 60 °C, a resettable thermal fuse on every cell limits the output. At 90 °C, the fire suppression system releases an agent that displaces oxygen and cools the battery.
Easy servicing
Warranty and post-warranty service directly from the manufacturer. 24/7 remote monitoring, with all data stored on our own servers in the EU. Individual components, including cells, can be replaced, and all spare parts are kept in stock.
Control system
Our own EMS for smart battery control and remote monitoring in every battery. Predictive control, 24/7 management and remote OTA (over-the-air) firmware updates.
Modularity and scalability
Modular rack design scalable in 12 kWh steps — from 60 to 1,140 kWh. Easy integration into existing infrastructure, with the option to increase power and capacity in the future.
Energy Management System
Our own EMS
Our own control unit with unique software. It actively controls the battery storage and selected inverter types and provides 24/7 remote monitoring. AI-based smart control optimises when energy is stored and when it is used.
24/7 remote monitoring
Online overview of the system status down to individual cells.
Smart energy management
Optimises charging and discharging according to consumption, PV generation and spot market prices.
Scheduler
Automatic time windows for individual operating modes.
Peak shaving
Cuts demand peaks and reduces reserved grid capacity.
Modbus RTU/TCP and API
Communication via standard industrial interfaces and integration with third-party dispatch control.
Conditioning charge & remote updates
Automatic battery protection in winter, remote firmware and feature updates, alarm management and event history.
Components and technology
What’s inside the battery
Resettable thermal fuses
- A fuse on every cell connection monitors the temperature.
- If a cell overheats, it is temporarily disconnected without a technician having to intervene.
Flexible bolted connections
- Resistant to vibration and mechanical stress.
- Lower contact resistance and quick replacement of individual cells during servicing.
BMS & active balancer
- Voltage and temperature monitoring, active cell balancing.
- Alarms, remote supervision via Rebox, EMS integration.
