According to the manufacturer, the hybrid inverter operates with an efficiency of up to 98.2 per cent and offers backup power capability with integrated island protection in accordance with VDE-AR-N 4105. Up to five battery modules can be connected to the inverter in three phases. This provides a storage capacity of up to 25.6 kWh. Expansion packs allow the capacity to be increased at a later date without external rewiring.
The EMS monitors energy production, consumption and battery status in real time. It controls the charging and discharging of the batteries and prioritises loads. The storage system itself uses LFP batteries and has continuous cell status monitoring. A steel housing and integrated aerosol fire extinguisher provide additional protection. Ubbink also offers a ten-year guarantee on charging cycles. (nhp)
