GoodWe GW6K-EHA-G20 6 kW Single-Phase Hybrid Solar Inverter 2 MPPT

The GoodWe GW6K-EHA-G20 single-phase hybrid solar inverter is a 6 kW solution designed for residential photovoltaic installations with energy storage. It is part of the GoodWe ESA series and integrates 2 independent MPPT trackers, high-voltage battery connection, 6 kVA Backup output, AFCI, surge protection, and WiFi, LAN, Bluetooth and RS485 connectivity, enabling intelligent management of solar production, household consumption, the battery and energy exchange with the grid.

The GW6K-EHA-G20 supports up to 12 kW of PV input power, twice its nominal 6 kW AC output. This oversizing capability makes it possible to use a larger solar panel array and improve generation during periods of lower irradiation, directing the available energy to direct consumption, battery charging or grid management depending on the installation configuration.

6 kW single-phase hybrid inverter

The GoodWe GW6K-EHA-G20 provides a 6 kW grid output rated power and a rated and maximum apparent power of 6 kVA. It is ready for single-phase 220, 230 and 240 V grids and operates at a nominal frequency of 50/60 Hz.

• AC rated power: 6 kW.
• Rated grid apparent power: 6 kVA.
• Maximum grid apparent power: 6 kVA.
• Grid configuration: single-phase L/N/PE.
• Nominal voltage: 220 / 230 / 240 V.
• Voltage range: 170-280 V.
• Nominal frequency: 50/60 Hz.
• Power factor: approximately 1, adjustable from 0.8 capacitive to 0.8 inductive.
• THDi harmonic distortion: less than 3%.

2 independent MPPTs for the PV array

The GW6K-EHA-G20 incorporates 2 independent MPPT trackers, with one string input for each MPPT. This configuration makes it possible to split the PV array into two groups of panels and manage installations with different orientations, tilts or irradiation conditions independently.

• Number of MPPTs: 2.
• Strings per MPPT: 1 + 1.
• Maximum current per MPPT: 20 A.
• Maximum short-circuit current per MPPT: 26 A.

The allowable current of up to 20 A per MPPT ensures compatibility with today’s high-power photovoltaic modules, provided that all electrical limits specified by GoodWe are respected.

Up to 12 kW of PV power

The inverter supports a maximum PV input power of 12 kW, equivalent to an array oversizing of up to 200% compared with its 6 kW nominal AC output.

• Maximum PV power: 12 kW.
• Maximum input voltage: 600 V DC.
• MPPT operating range: 40-560 V.
• MPPT range at rated power: 210-500 V.
• Nominal input voltage: 400 V.
• Start-up voltage: 50 V.

When the PV voltage is between 560 and 600 V, GoodWe establishes specific operating conditions, so string sizing must be carried out strictly in accordance with the manufacturer’s instructions.

Compatible with high-voltage LiFePO4 batteries

As a hybrid inverter, the GoodWe GW6K-EHA-G20 is designed to work with compatible high-voltage LiFePO4 batteries. The system uses a battery input with a nominal voltage of 380 V and an operating range of 350 to 550 V.

• Battery type: LiFePO4.
• Number of battery inputs: 1.
• Battery nominal voltage: 380 V.
• Voltage range: 350-550 V.
• Start-up voltage without PV production: 380 V.
• Communication with BMS: CAN.

Storage makes it possible to save surplus solar energy for later use at night, during periods of low PV generation or whenever it is desirable to reduce the energy drawn from the grid.

Up to 9 kW battery charging power

The GW6K-EHA-G20 offers a charging capacity above its nominal AC output power, reaching a maximum battery charging power of 9 kW.

• Maximum continuous charging current: 23.7 A.
• Maximum continuous discharging current: 17.4 A.
• Maximum charging power: 9 kW.
• Maximum discharging power: 6.6 kW.

The effective available power will also depend on the characteristics and limits of the installed battery module, as well as its temperature and state of charge.

6 kVA Backup output

The inverter includes a 6 kVA Backup output to supply selected loads when a grid outage occurs, provided that the installation has a battery and is correctly configured for this operating mode.

• Backup rated power: 6 kVA.
• Backup maximum continuous power: 6 kVA.
• Peak power: up to 12 kVA for 10 seconds.
• Maximum power via bypass: 12 kVA.

The ability to deliver up to twice its nominal power for 10 seconds helps support certain loads that require high starting power.

UPS-level switching in under 4 ms

The GoodWe ESA series incorporates UPS-level switching in under 4 ms. This fast response is intended to keep compatible household loads powered when an unexpected grid failure occurs.

The ESA architecture also includes internal bypass capability to support whole-home backup solutions when the installation is sized according to GoodWe specifications.
