JinkoSolar SunGiga JKS-261KLAA-135PLAA is an LFP battery energy storage system for commercial and industrial use, with 261 kWh nominal energy and supplied as an AC block. It uses liquid cooling or air cooling and 314 Ah prismatic cells. The unit weighs 2.8 tonnes (6,173 lb) and has a 702 to 936 V DC window.
Use Cases
The specifications of JinkoSolar SunGiga JKS-261KLAA-135PLAA together point to use behind the meter inside a customer's own electrical installation. Its energy capacity is within the commercial and industrial range, and it connects at 400 V, a low-voltage AC connection.
Capabilities
JinkoSolar SunGiga JKS-261KLAA-135PLAA specifications suggest renewable colocation, operating alongside a wind or solar plant on one site, as its AC block includes the inverter. About 1.93 h of storage at full power, calculated from 261 kWh and 135 kW, makes it a candidate for 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.
Site Space Required
Shared: one 3 m aisle serves both neighbours. Dedicated: each unit keeps its own 3 m, so gaps double to 6 m.
Single unit — matches the stored area_sqm convention.
