Hoymiles HoyPrime 5MW/10MWh is a containerized LFP battery energy storage system supplied as an AC block. It provides 10.03 MWh nominal energy with about a 2-hour duration and 86% DC round-trip efficiency. The system uses liquid cooling and weighs 2 tonnes (4,409 lb).
Use Cases
Use in front of the meter is consistent with the specifications of Hoymiles HoyPrime 5MW/10MWh. Its energy capacity is within the utility-scale range, and it connects at medium voltage (10 - 35 kV). Its supported protocols include IEC61850 and Goose, used in utility control systems.
Capabilities
The shortest listed configuration of 2 h makes Hoymiles HoyPrime 5MW/10MWh a candidate for capacity value, counting as firm supply toward a network's peak needs. An AC block with the inverter included points to renewable colocation, operating alongside a wind or solar plant on one site. The specifications suggest peak shaving, reducing the peak load at the connection point. That configuration indicates grid services, work that helps keep the electricity network running.

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.
