In today's evolving energy landscape, the line between residential and commercial power needs continues to blur. The GoodWe ET Series meets this challenge head-on, delivering a sophisticated three-phase hybrid solution that combines exceptional power handling with intelligent energy management.
Power that adapts to demand
Understanding that modern energy needs fluctuate throughout the day, the ET Series introduces revolutionary power handling capabilities. Available in models from 5kW to 29.9kW, these inverters feature 110% overloading capacity, ensuring reliable performance even during peak demand periods. This robust power delivery is complemented by the ability to manage 100% unbalanced output in backup mode, maintaining critical operations when grid power fails.
Engineering for uninterrupted operation
The ET Series transforms how we approach backup power. Its sophisticated UPS functionality achieves switching times under 10 milliseconds – so quick that even sensitive electronics remain operational during grid interruptions. This near-instantaneous response ensures critical systems, from air conditioning to medical equipment, continue functioning without disruption.
Storage flexibility that drives independence
At the heart of the ET Series lies its versatile battery integration capabilities. Supporting a high voltage range from 180V to 600V with a nominal 500V, the system accommodates diverse storage configurations. This flexibility extends to charging and discharging power, managing from 7500W to 30000W depending on the model, ensuring optimal energy management across varying demands.
Intelligence that optimises savings
The ET Series doesn't just store and deliver power – it manages energy intelligently. Through sophisticated export limitation and time-of-use management, the system maximises self-consumption while minimising grid reliance. This smart approach to energy management translates directly into reduced operational costs and enhanced energy independence.
Built for environmental extremes
Engineered for durability, the ET Series employs natural convection cooling, eliminating fan noise and maintenance requirements. The IP66-rated enclosure ensures reliable operation from -35°C to +60°C, making it suitable for installations from coastal environments to alpine conditions.
