Description
30 kW STS for ESA all-in-one systems
GoodWe GW30K-STS-G10 is a 30 kW static transfer switch for the ESA Series all-in-one storage system: 63 A maximum, on/off-grid transfer in ≤ 4 ms, wall-mounted IP54.
30 kW rated on the grid, back-up, smart-port and inverter sides.
Maximum current 63 A; rated 43.5 A at 400 V.
On/off-grid transfer ≤ 4 ms.
Wall-mounted IP54 enclosure, 506 × 590 × 180 mm, 12.5 kg, natural convection.
30 kW, 63 A, for one ESA inverter.
Grid, back-up, smart-port and inverter sides are rated 30 kW. Maximum current is 63 A. The ESA 5–30 kW manual limits this switch to ≤ 30 kVA and one hybrid inverter.
Transfer in ≤ 4 ms.
On/off-grid transfer time is ≤ 4 ms. Communication with the inverter is RS485.
IP54 wall box, 12.5 kg.
Dimensions 506 × 590 × 180 mm, natural convection, noise 35 dB, −35 to +60 °C, altitude 4000 m, anti-corrosion class C4L.

Backup switching on an ESA 5–30 kW system
An ESA all-in-one storage system needs a wall-mounted transfer switch for grid and backup operation up to 30 kW.
GW30K-STS-G10 is the 30 kW STS in the EMEA datasheet, named in the ESA 5–30 kW and 3–10 kW manuals.
- One hybrid inverter, ≤ 30 kVA.
- Wall: 506 × 590 × 180 mm, 12.5 kg, IP54.

Which inverters is GW30K-STS-G10 paired with?
The EMEA datasheet designs this switch for the ESA Series all-in-one storage system (single- and three-phase). The ESA 5–30 kW manual names GW30K-STS-G10 at ≤ 30 kVA with one hybrid inverter. It is not the 125 kW STS used with ET 80–100 kW.
