Notes:
- *¹: For 1000V installations, the maximum operating voltage is 950V. As a safety measure, a warning will appear if the PV string voltage exceeds 600V.
- *²: In accordance with local grid regulations.
- *³: Achievable only with sufficient battery power and power from the PV string.
- *⁴: CAN communication is configured by default. To use RS485 communication, the appropriate communication cable must be changed.
- *⁵: Without active backup output.
- *⁶: For Belgium, the maximum apparent output power (VA): GW5K-ET is 5000; GW6.5K-ET is 6500; GW8K-ET is 8000; GW10K-ET is 10000.
- *⁷: When the battery is not connected, the inverter starts working only when the PV string voltage is higher than 400V.
- Current certificates are available on the GoodWe website.
