Equipped with lithium-iron-manganese-phosphate batteries, the storage solution has a capacity that starts at 5.5 kWh. The company also states that the system has a minimum of 3,000 loading cycles at 80% capacity use and a bypass function as well. With one switch, says Knubix, the storage unit can be bypassed for normal grid operation. There is also an integrated energy management system for optimum self-consumption. In the case of a blackout, the system provides a secure power supply and uses the stored energy. The Knut 3 x 3000 with an output-load of 3 x 3,000 VA is 197 kg heavy and is 1,390 x 600 x 580 mm in dimension. It is IEC 61850 protocol ready as well.
