GoodWe GW6.5K-ET
GoodWe GW6.5K-ET is a hybrid inverters product in the de-linker PV catalog for installer and project procurement.
- Backup output matches the inverter's full rated AC power (5000-10000 VA across the range), with switchover in under 10 ms, so approved loads keep running at full power, not a fraction of it.
- Up to 98.2% max. efficiency (97.2-97.5% European weighted) across the range, with a 180-600 V battery window and 2 MPP trackers for a single- or dual-string residential PV array.
- IP66-rated enclosure for outdoor wall mounting.
- GoodWe lists this range against the Lynx D battery bank (ARM 28 / DSP 12 firmware or higher) for factory-approved warranty coverage.

Configuration 3
GoodWe's Battery Compatibility Overview lists the Lynx D bank (LX D5.0-10) against the ET 5-10 kW range.
- Firmware condition: the inverter needs ARM 28 / DSP 12 firmware or higher for the Lynx D pairing.
- Battery window: the ET accepts battery voltages of 180-600 V; match the pack voltage before the BOM is final.
- Warranty angle: GoodWe ties factory-approved warranty coverage to the listed pairing, so keep to the compatibility overview when substituting.
Per GoodWe's datasheet, max PV input is 7,500 W on the GW5K-ET, 9,700 W on the GW6.5K-ET, 12,000 W on the GW8K-ET and 15,000 W on the GW10K-ET.
- Trackers: 2 MPP trackers, laid out for a single- or dual-string residential array.
- Efficiency: up to 98.2% max efficiency on the 8 and 10 kW models, 98.0% on the 5 and 6.5 kW models, with 97.2-97.5% European weighted across the range.
- Oversizing ratio: the DC ceiling is roughly 1.5 times the AC rating on every model (simple arithmetic on the figures above), so plan strings against the model you quote.
Yes, with the GoodWe SEC1000S, which GoodWe builds for the ET 5-10 kW series specifically.
- Parallel control: the SEC1000S provides export power control plus parallel control for up to 10 inverters and carries a built-in GM3000 meter.
- Single-inverter homes: the EzManager3000 home EMS covers 1 hybrid inverter, 2 EV chargers, 1 heat pump and 12 Shelly devices from one controller.
- Model mix: the range spans 5, 6.5, 8 and 10 kW three-phase models, so match the unit count and rating to the service size before quoting.
Operation & warranty 1
Backup output matches the inverter's full rated AC power, 5,000 to 10,000 VA across the range, with switchover in under 10 ms per GoodWe.
- No derating: approved loads keep running at full power in backup, not at a fraction of the on-grid rating.
- Three-phase: all four models (GW5K, GW6.5K, GW8K, GW10K-ET) are three-phase units.
- Duration: backup runtime depends on the connected Lynx D capacity, so size the battery bank against the loads you intend to carry through an outage.
Installation & wiring 1
Every grid-tied ET installation needs the GoodWe GM330 CT meter for export limiting and self-consumption metering.
- Universal meter: the GM330 is a clip-on unit covering 1P2W, 3P3W and 3P4W services.
- Mounting: the inverter itself is IP66 rated for outdoor wall mounting.
- Surge protection: GoodWe's listing shows Type II surge protection on the DC side and Type III on the AC side, so record that basis in the project documentation.
Availability & compliance 1
GoodWe lists the range against VDE-AR-N 4105, VDE 0126-1-1, EN 50549-1, G98, G99, G100 and CEI 0-21.
- Germany: VDE-AR-N 4105 and VDE 0126-1-1 are both on the listed certificate set.
- Other markets: EN 50549-1 plus the G98, G99, G100 and CEI 0-21 codes named above.
- Paperwork: the certificate documents for the grid operator submission are confirmed with the quote; downloads and source links are attached where available.
