The 99.99 model in the grid application
The project documents call for this exact G10 nameplate rather than an adjacent 100 kW model.
The datasheet lists 99.99 kW nominal and 99.99 kVA maximum to and from the grid for this model.
- Application: under the exact name GW99.99K-ET-G10.
- Grid figure: 99.99 kVA.

Product questions
Which model figure should the grid application use for GW99.99K-ET-G10?
Use 99.99 kW as the model figure for the GW99.99K-ET-G10. The datasheet lists the model as GW99.99K-ET-G10, and the user manual gives the three-phase unbalanced output as 1/3 x 99.99 kW.

Two GoodWe documents carry this pair: the Battery Compatibility Overview, ET (80–100 kW) column, and a signed Compatibility Statement of 2025-04-07 naming GW80K-ET-G10, GW99.99K-ET-G10 and GW100K-ET-G10 against GW61.4 to GW112.6-BAT-AC-G10. The Battery Compatibility Overview (p. 6) states that GW61.4-BAT-AC-G10 paired with ET (80–100 kW) cannot reach the inverter's full power output. GoodWe's BAT-C datasheet (p. 2) gives the GW61.4-BAT-AC-G10 an operating voltage range of 275.52 to 346.56 V (nominal 307.2 V); the ET 75–100 kW datasheet (p. 2) gives a battery voltage range of 300 to 800 V and a start-up voltage of 300 V.
