SUN-STS500L - 500 kW STS switching module, grid, load, generator

SUN-STS500L is a 500 kW three-phase STS module of the Deye C&I ESS solution, which switches between grid-connected operation, off-grid mode and a diesel generator in less than 10 ms. It has independent ports for grid, load and generator, each rated for 500 kW, and links the PCS modules together.

Main features:

• Rated power: 500 kW, three-phase
• Rated current: 758/725 A
• Operating voltage: 220/380 V, 230/400 V
• Switching time: under 10 ms
• PCS connection: 5 x 100 kW or 4 x 125 kW
• Protection rating: IP20

The module switches without a noticeable interruption between grid-connected operation, off-grid mode and a diesel generator. The generator, load and grid ports are independent, and each path supports 500 kW.

One STS module can connect up to five 100 kW PCS modules or four 125 kW PCS modules. Five STS modules in parallel can support twenty-five 100 kW PCS modules or twenty 125 kW PCS modules, forming a 2.5 MW system.

The module has natural cooling, overvoltage category OVC III and complies with IEC/EN 61439-1/-2.
