GoodWe GW10K-EHA-G20 10 kW Single-Phase Hybrid Solar Inverter 2 MPPT

The GoodWe GW10K-EHA-G20 single-phase hybrid solar inverter is a 10 kW unit designed for residential self-consumption photovoltaic systems with energy storage. It is part of the GoodWe ESA series and stands out for integrating 4 independent MPPT trackers, up to 20 kW of PV input power, high-voltage battery connection, 10 kVA Backup output, AFCI, surge protection, and WiFi, LAN, Bluetooth and RS485 connectivity.

Its high PV input capacity allows the solar array to be oversized up to 200% of the AC rated power, while the four MPPTs provide great flexibility to distribute the panels across different orientations, tilts or roof areas. In addition, it can work with the compatible storage modules of the GoodWe ESA platform to increase self-consumption and provide backup power during grid outages.

• Maximum current per MPPT: 20 A.
• Maximum short-circuit current per MPPT: 26 A.

Up to 20 kW of PV input power

GoodWe allows the GW10K-EHA-G20 to be connected to a maximum PV power of 20 kW, equivalent to 200% of its AC rated output power. This oversizing capability helps increase generation during the early morning and late afternoon, as well as during periods of lower irradiance.

The additional energy produced can be used for direct household consumption, battery charging, or export to the grid, depending on the configuration and the limits set in the installation.

• Maximum PV power: 20 kW.
• Maximum input voltage: 600 V DC.
• MPPT operating range: 40-560 V.
• MPPT range at rated power: 190-500 V.
• Nominal input voltage: 400 V.
• PV start-up voltage: 50 V.

Compatible with high-voltage batteries

As a hybrid inverter, the GoodWe GW10K-EHA-G20 includes a dedicated input for compatible high-voltage LiFePO4 batteries. It works with a nominal battery voltage of 380 V and supports an operating range of 350 to 550 V.

• Battery type: LiFePO4.
• Number of battery inputs: 1.
• Nominal battery voltage: 380 V.
• Battery voltage range: 350-550 V.
• Start-up voltage: 380 V.
• Communication with BMS: CAN.

This architecture makes it possible to store surplus solar production for later use at night, during hours with higher electricity tariffs, or when PV generation is not enough to cover consumption.

Up to 13.5 kW battery charging power

The GW10K-EHA-G20 offers high storage management capability. GoodWe specifies a maximum charging power of 13.5 kW and a maximum discharge power of 11 kW.

• Maximum continuous charging current: 35.6 A.
• Maximum continuous discharge current: 29 A.
• Maximum charging power: 13.5 kW.
• Maximum discharge power: 11 kW.

These values make it possible to take advantage of high-capacity storage systems and quickly manage large PV surpluses, always within the power and current limits of the installed battery module.

Compatible with GoodWe ESA battery modules

The inverter is designed to work within the GoodWe ESA storage ecosystem. Available modules include the GW8.3-BAT-D-G20 8.32 kWh unit, as well as other compatible capacities depending on the system configuration.

The modular, stackable architecture of the ESA series makes it possible to expand storage capacity as household energy needs grow, providing a scalable solution for new projects or future expansions.

10 kVA Backup output

The GoodWe GW10K-EHA-G20 includes a 10 kVA Backup output, capable of maintaining selected loads when the grid fails, provided the installation includes a battery and has been correctly designed for this function.

• Backup rated power: 10 kVA.
• Backup maximum continuous power: 10 kVA.

• Maximum power via bypass: 14.5 kVA.
• Output voltage: 220 / 230 / 240 V.
• Frequency: 50/60 Hz.
• THDv with linear load: less than 3%.

The ability to provide up to 20 kVA for 10 seconds helps start certain loads with high inrush currents, always within the conditions specified by GoodWe.

Backup switchover in less than 4 ms

The GoodWe ESA series is designed to provide UPS-level response, with a backup switchover time of less than 4 ms. This fast transition is intended to keep compatible household loads powered during sudden grid interruptions.

This feature is especially useful in installations where lighting, communications, computer systems, refrigerators or other priority loads need to remain operational during a power outage.

High conversion efficiency

The inverter achieves a maximum efficiency of 97.5%, reducing losses during PV energy conversion.

• Maximum efficiency: 97.5%.

• Maximum battery-to-AC efficiency: 97.8%.

These performance figures make it possible to use both solar energy and stored battery energy efficiently.

Integrated AFCI for arc fault detection

The GW10K-EHA-G20 includes AFCI as standard, a system designed to detect certain electrical arcs that may occur on the DC side of the photovoltaic installation.

This function increases the monitoring level of the PV array and complements the other electrical protections integrated into the inverter.

Smart energy management

The ESA platform includes energy management functions aimed at maximizing self-consumption and optimizing battery use. GoodWe highlights the use of a smart EMS to coordinate solar production, household consumption, the battery and the grid.

The system can use the battery to store solar surplus and deliver energy later, helping reduce dependence on the grid and increasing the share of photovoltaic energy used directly in the home.

Modular and expandable ESA system

GoodWe has designed the ESA series as a modular residential storage platform. The system can combine the inverter with different battery modules and be expanded later to increase available capacity.

The architecture supports up to 6 battery modules per column, with scalable capacities depending on the type and number of batteries installed. GoodWe also allows certain configurations that combine modules of different capacities or ages, always within the manufacturer’s compatibility rules.

All-in-One design for easier installation

The GoodWe ESA series is designed as an All-in-One storage solution in which the inverter, batteries, UPS switching system and enclosure are part of a preconfigured modular architecture.

This approach aims to simplify wiring, reduce the number of external components and speed up installation compared with a system made up of fully independent devices.
