GoodWe GW40K-ET-10

GoodWe GW40K-ET-10 is a three-phase C&I hybrid inverter rated 40 kW with 3 MPP trackers and 60 kW of PV input.

  • Backup output matches the inverter's full rated AC power; up to 98.1% max. efficiency (97.5% European weighted); 100 A max. battery charge/discharge current.
  • GoodWe lists the Lynx C battery bank against this tier, but flags that the smaller LX C101-10 and LX C120-10 configurations cannot reach the inverter's full rated power — LX C138-10 and LX C156-10 are the sized-for-power options.
  • GoodWe also lists the BAT-AC cabinet here, with the same caveat on the smaller GW61.4-BAT-AC-G10 model; the larger GW112.6-BAT-AC-G10 does not carry that limitation.

Configuration 2

The 40 kW model carries 3 MPP trackers and up to 60 kW of PV input; the 50 kW model carries 4 trackers and up to 75 kW. Both take two strings per tracker.

  • String window: MPPT operating range 165 to 850 V, maximum input voltage 1000 V.
  • Tracker currents: 42 / 32 / 42 A on the 40 kW model, 42 / 32 / 42 / 32 A on the 50 kW model.
  • AC side: 40 or 50 kW nominal at 380 / 400 V three-phase, with maximum grid current 58.0 A or 72.5 A at 400 V respectively.

GoodWe lists the Lynx C range and the BAT-AC cabinets against the ET 40-50 kW tier, but not every size reaches full inverter output.

  • Sized for full power: LX C138-10 and LX C156-10; the smaller LX C101-10 and LX C120-10 are listed but cannot reach the inverter's full rated power.
  • BAT-AC: the GW112.6-BAT-AC-G10 runs at full power (ARM 10 or higher); the smaller GW61.4-BAT-AC-G10 is capped below full inverter output on this tier.
  • Battery input: one input at 200 to 800 V and 100 A, with 44 kW (40 kW model) or 55 kW (50 kW model) charge and discharge.

Installation & wiring 1

Yes. The units are rated IP66, wall mounted, and operate from -35 to +60 C, so outdoor mounting at the installation is within specification.

  • Handling: 520 x 660 x 260 mm at 62 kg (40 kW) or 65 kg (50 kW).
  • Metering: the GoodWe GM3000 three-phase meter is the required unit for export control on this power tier.
  • Monitoring option: the SEC3000C connects GoodWe on-grid and hybrid inverters in parallel and includes a built-in meter.
  • BMS link: CAN to the battery.

Operation & warranty 1

Yes, for backup only. GoodWe's datasheet notes the on-grid AC output requires an additional STS box for UPS-level switching to backup mode; normal on-grid operation needs no extra hardware.

  • Backup rating: back-up nominal apparent power equals the full rated output, 40 or 50 kVA by model.
  • Standby draw: night self-consumption is below 15 W per GoodWe's datasheet.
  • Efficiency: 98.1 percent maximum, 97.5 percent European weighted, 97.7 percent battery to AC.

Availability & compliance 1

The fact set on file for this family does not include a grid-code certificate list, so confirm the certificate set for your target grid operator with the quote.

  • Documents: the GoodWe ET50 series 40-50 kW datasheet (EMEA, EN) is on file.
  • Protection hardware: DC surge protection Type II (Type I + II optional), AC surge protection Type II, AFCI optional; anti-islanding and remote shutdown are integrated.
  • Ordering: name the country and grid operator in the project inquiry and we confirm the applicable certificates before the order.
