System efficiency up to 92.9% @0.25°C

A 1 MWh power plant generates over 300,000 yuan in additional revenue throughout its lifecycle.

Pioneering in 3 major industries	Dual-Engine Air-Liquid Intelligent Cooling Technology	Based on different temperature environments, the cooling mode is intelligently selected to achieve minimum power loss, improving the overall system efficiency by 1-2% over the entire year.
	Stacked Light Energy Storage Technology	Innovatively, we’ve added photovoltaic power generation to the site, further reducing energy storage losses and boosting the overall system’s round-trip efficiency by 0.5–1% annually.
	AI All-Time Equalization	By collecting data from each battery cell and leveraging large-scale AI domain models for big data analytics, we can autonomously optimize charging and discharging strategies in conjunction with environmental conditions.

3 Major Upgrades	Newly upgraded SiC-PCS	High-efficiency third-generation SiC semiconductor—silicon carbide core components with a maximum conversion efficiency of 99%.
	Highest energy density	Energy density: 198 Wh/m²; area footprint reduced by 16%; lower delivery costs.
	Multiple layers of security protection	Multi-level fire prevention and all-weather alerts, high-strength armored cabinet, and highly protective Seagull system.
