Sub-10ms source transfer is the difference between basic backup and a genuinely resilient energy platform. The SUN-STS500L coordinates grid, PCS, load and generator paths at up to 500kW, helping factories, data centers, commercial buildings and critical infrastructure maintain continuity through grid disturbances. One unit can aggregate up to four 125kW PCS modules or five 100kW units, giving system designers a clean, scalable switching layer for high-power C&I energy-storage and microgrid projects.

Switching capacity	500 kW
Grid/PCS, Load and Generator sides	758/725 A at 220/380 or 230/400 V
System	three-phase 3L/N/PE; 50/60 Hz
Off-grid transfer time	<10 ms
Protection class	IP20; overvoltage category III
System matching	up to five 100kW PCS units or four 125kW PCS units per STS500L
Application	grid/PCS/generator transfer for C&I backup and microgrid systems
