GoodWe ESA 29.999 kW - GW29.999K-ETA-G20

GoodWe ESA 29.999 kW – The all-in-one energy storage solution for maximum independence.

With the GoodWe ESA series, you get a high-performance all-in-one energy storage solution for maximum independence and efficiency. The three-phase hybrid Inverter combines state-of-the-art high-voltage battery technology with up to 200% PV oversizing, enabling simultaneous battery charging and power supply to your loads – for maximum self-consumption rates and optimal utilisation of your PV system.

Thanks to an integrated emergency power function with a switchover time of ≤ 4 ms, up to 80 A of backup power and scalable battery capacity of up to 108 kWh, the system grows flexibly with your requirements. The ESA also impresses with whisper-quiet operation from 35 dB, 98% efficiency with SiC technology, and a six-layer safety architecture for reliable protection – even at temperatures as low as −20 °C

Whether for a detached house or a small business: with the GoodWe ESA, you are investing in a future-proof, smart and expandable energy storage solution.
