Product Description

The Goodwe GW20K-ET 20kW HV Three-Phase Hybrid Inverter raises the bar in premium residential and light commercial projects that require high power, robust storage, and operational continuity. With 2 MPPTs capable of supporting up to 2 strings per tracker, compatibility with high-voltage batteries (CAN/RS485), and a three-phase backup output with transfer time <10 ms, this 20 kW hybrid combines design versatility, 98% efficiency, and IP66 protection for safe outdoor operation.

Main Features

Nominal grid power: 20 kW (20 kVA) with S_max 22 kVA.
2 independent MPPTs, up to 2 strings/MPPT; range 200–850 Vdc (Vmax 1000 Vdc).
I_max per MPPT 30 A and I_sc 38 A for high-current modules.
HV battery 200–800 V (nom. 500 V); ±50 A continuous; native integration with Lynx Home F.
Three-phase EPS 20 kVA; overload 24 kVA 60 s / 32 kVA 3 s; switching <10 ms.
IP66, -35~+60 °C, noise <45 dB; SEMS 24/7 monitoring.

Advantages or Benefits

Scalable autonomy: large-capacity HV banks to cover peaks and nights with TOU and Peak Shaving strategies.
Instant backup: UPS-type EPS ensuring continuity for lighting, IT, cameras, and critical processes.
Flexible design: two high-current MPPTs allow splitting arrays by orientation or technology.
Safety and compliance: integrated DC isolator and Type II SPD; anti-islanding and RCMU according to standards.
Efficient operation: 98% efficiency and 99.9% MPPT maximize usable kWh and reduce losses.
Advanced management: with Smart Meter, zero export, phase balancing, and load automation are enabled.

Purpose or Applications

Aimed at large homes, businesses, offices, and small workshops, the GW20K-ET allows for growth in photovoltaic power, storage of surplus for nighttime use, and maintaining supply during micro-outages. It is ideal when export limitation and prioritization of internal consumption such as HVAC, DHW, or charging points are required, maintaining high annual performance even with latest-generation panels and long strings.
