GoodWe GW50K-ET-10 Hybrid Inverter ET Series (B-Stock)

GoodWe GW50K-ET-10 Hybrid Inverter ET Series (B-Stock)

Notice: B-Stock:This is a customer return with the original packaging opened and damaged. The device itself is unused.
The WiFi-LAN dongle and the GM330 smart meter are included in the scope of delivery. Please note that suitable current transformers are additionally required and must be added separately. For backup power operation, the GoodWe STS box is also required.

The new 40 kW and 50 kW models of the GoodWe ET hybrid series are specifically designed for commercial and industrial applications. With up to four MPPT trackers, high input current capability, integrated surge protection, and AFCI, they offer the flexibility required for demanding system configurations.

The system can operate both grid-parallel and grid-independent and can also be connected in parallel. This enables a wide range of applications such as self-consumption optimization, peak shaving, time-of-use strategies, and grid support.

When combined with the STS Box (Static Transfer Switch), reliable switching during backup operation is ensured—at a level equivalent to an uninterruptible power supply (UPS).

Features:

  • Integrated surge protection: DC Type 1+2 / AC Type 2
  • Four high-performance MPPT trackers with up to 42 A
  • Includes WiFi dongle and GM330 smart meter
  • Battery input current up to 100 A
  • IP66 protection rating
