JinkoSolar today announced to deliver 15.48MWh storage system to the GWI’s Tiger Neo + ESS utility project in Japan, including 72 sets of 215kWh liquid cooling containerized energy storage system SunGiga.
Profitability, safety, integration, and operation & maintenance (O&M) costs, are always major concerns for stakeholders when choosing an ideal C&I ESS. The SunGiga is designed for the 250kW mainstream market, available for 2-hour and 4-hour applications. The SunGiga was jointly pre-commissioned so that all parameters were set before leaving the manufacturing base, decreasing on-site commissioning time and guaranteeing early revenue for project owners.
Due to the patent designed liquid cooling technology, the SunGiga comes with a lower cell temperature difference within 2.5 Celsius degrees, extending the lifetime of batteries and significantly improving the charging and discharging efficiency. Compared with the conventional air-cooling design, the liquid-cooled system also significantly reduces thermal management energy consumption. The automatic state of charge (SoC) calibration and the automated coolant refilling considerably reduce operating and maintenance (O&M) costs.
Safety is the top priority for battery system technology. JinkoSolar’s SunGiga offers comprehensive safety design from the cell, rack, pack, and system levels. AI-assisted cell monitoring technology performs high-precision online computing of cell status and provides early-stage warnings to prevent thermal runaway. Five layers of protection mitigate electrical hazards. SunGiga also offers a combustible gas detection and ventilation system as well as an extra water-based spray suppression system.
