GoodWe GW15K-ET 15kW Three-phase Hybrid Inverter

Goodwe GW15K-ET 15kW Three-phase Hybrid Inverter

GoodWe GW15K-ET ET Series Three Phase High Voltage Hybrid Inverter with maximising energy back-up for high power PV rooftops.
The trend of increasing PV module yield is influencing overall PV system requirements. At the forefront of development, GoodWe’s ET inverters efficiently meet the needs of powerful solar rooftops to facilitate energy back-up, peak shaving and load management for optimised autonomy and reduced energy cost. The ET series can be combined with a range of battery capacities and brands, including the GoodWe Lynx Home F.
• Surge protection Type 2 on DC side
• Backup with UPS level switching < 10ms
• IP66 ingress protection
• Peak shaving

Highest safety standards
Thanks to the in-built DC type II SPD, the ET series can protect DC side from lightning strikes and save the cost of an external device.
• Built-in Type II SPD on DC side
• IP66 ingress protection

Optimised energy autonomy
100% unbalanced output to compensate load differences in self-consumption and backup modes. The UPS-level switching ability ensures the power supply security and reduce the risk of outage for critical loads.
• Wide battery voltage range (200-800V)
• Integrated dynamic power export limit and load monitoring

Smart and efficient operations
Supports multiple communication protocols for smart home integration and provides DRY contact for interaction with SG-ready heat pumps, 3rd party EV chargers or other large loads.
