Hoymiles HoyCore Outdoor Battery System is an LFP battery system for commercial and industrial use. It provides 344 kWh nominal energy as a DC block and uses liquid cooling. The system uses 280 Ah prismatic cells.
Use Cases
Use behind the meter at a customer's own premises is consistent with the specifications of Hoymiles HoyCore Outdoor Battery System. By energy capacity, it belongs to the commercial and industrial class.
Capabilities
A DC block that connects through a separate inverter makes Hoymiles HoyCore Outdoor Battery System a candidate for renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. Its 0.5C rating points to peak shaving, reducing the peak load at the connection point.

Plant Round-Trip Efficiency
The calculator estimates the full "plant" round-trip efficiency (RTE) at the point of interconnection. Some values are pre-blocked depending on information on a particular ESS. The rows that are marked "each way" are one-way efficiencies; they are applied on charge and again on discharge. We then square them. To enter a bundled PCS efficiency value, use its rated-power value, not peak. If the PCS skid already includes the LV/MV transformer, set Transformer LV/MV to 100 % so those losses are not counted twice.
