Designed for industrial parks, PV-storage-charging stations, and distribution transformer areas, this modular string PCS delivers five core upgrades:

-
Full liquid cooling + high protection – IP66 and C5 anti-corrosion, sealed against dust, rain, and aggressive gases. Full rated output up to 50°C without derating. No air filter or fan maintenance. Pairs seamlessly with liquid-cooled battery systems for maximum summer availability.
-
98.8% peak efficiency – Three-level topology minimizes conversion losses, boosting arbitrage and demand-charge savings. Integrated high/low voltage ride-through prevents disconnection during grid disturbances, protecting critical loads.
-
Grid-forming capability – Three-phase four-wire off-grid operation builds stable voltage/frequency independently. Wave-by-wave current limiting and nonlinear load support, with fast seamless transfer (via external switchgear). Handles 100% unbalanced three-phase loads – ideal for aging distribution grids with severe phase imbalance.
-
Flexible cell compatibility – Optimized for 314Ah–350Ah large-format cells at 1000V system level. Supports AC/DC parallel expansion, smoothly adapting to 600Ah cells for future upgrades.
-
Integrated high-voltage box – Built-in BMS master control reduces components and commissioning time, lowering initial CAPEX. Compatible with BMS/EMS integration for flexible networking and faster delivery.
EAST Energy Storage – driving C&I storage value with power electronics core technology.
