Product details
Product information "GW GW20K-ETA-G20"
All‑in‑one system. Scalable storage from 5 kWh to 108 kWh.
Designed for three‑phase residential and small commercial applications, the inverter controls a high‑voltage LFP battery and includes intelligent energy management. ETA is available locally from 5 kW to 29.9 kW. With scalable storage from 5 kWh to 108 kWh, the ESA provides a compact solution for projects requiring higher power, whole‑site backup, or future capacity expansion.
