GoodWe GW10K-ES-C10 10 kW Single-Phase Hybrid Solar Inverter 2 MPPT ES Uniq

The GoodWe GW10K-ES-C10 single-phase hybrid solar inverter belongs to the ES Uniq series and is designed for residential photovoltaic installations with energy storage. It offers a rated power of 10 kW, incorporates 2 MPPT trackers, and enables integrated management of solar production, household consumption, low-voltage batteries, grid connection, and a backup output for essential loads.

The GW10K-ES-C10 supports up to 20 kW of PV input power, works with 48 V batteries, and provides up to 10 kW of charging power and 11 kW of discharging power. Its 10 kVA backup output, with UPS-equivalent switching in less than 4 ms, helps keep selected loads powered when grid supply is interrupted. It also features IP66 protection, integrated AFCI, and connectivity via RS485, WiFi, LAN, and Bluetooth.

10 kW single-phase hybrid inverter

The GoodWe GW10K-ES-C10 delivers a rated output power of 10 kW and a rated apparent power of 10 kVA. In grid-tied operation, it can reach up to 11 kW of active power and 11 kVA of maximum apparent power.

It is designed for single-phase 220, 230, or 240 V grids and can operate at 50 or 60 Hz. Its maximum grid output current reaches 50 A, while the power factor can be adjusted from 0.8 capacitive to 0.8 inductive.

2 MPPTs with four PV string inputs

The inverter features 2 independent MPPT trackers and allows two PV strings to be connected to each one. This 2+2 configuration provides flexibility for distributing solar panels across different orientations or roof areas.

Each MPPT supports a maximum input current of 32 A, with a maximum of 16 A per string, and a maximum short-circuit current of 48 A per MPPT. These characteristics make it suitable for pairing with modern high-power photovoltaic modules.

Up to 20 kW of PV input power

GoodWe specifies a maximum PV input power of 20 kW for the GW10K-ES-C10, equivalent to an oversizing of up to 200% compared with its 10 kW rated power.

The maximum input voltage is 600 V and the MPPT operating range is between 60 and 550 V. The nominal input voltage is 360 V and the start-up voltage is 58 V.

This range makes it possible to size systems with a module power higher than the inverter’s rated power, while always respecting the voltage, current, and configuration limits established by GoodWe.

48 V low-voltage batteries

The GoodWe ES Uniq GW10K-ES-C10 includes an input for low-voltage lithium-ion or lead-acid batteries. It operates with a nominal battery voltage of 48 V, a working range of 40 to 60 V, and a start-up voltage of 44.2 V.

The maximum continuous charge and discharge current reaches 200 A. The inverter can provide up to 10 kW of battery charging power and up to 11 kW of discharging power, offering high capacity for storing and recovering energy in high-consumption residential installations.

10 kVA backup output with switching under 4 ms

The backup output of the GW10K-ES-C10 provides a rated apparent power of 10 kVA. In off-grid operation it can reach 11 kVA and support a peak of up to 20 kVA for 10 seconds, a feature especially useful for powering equipment with high inrush currents.

GoodWe specifies a UPS-equivalent switching time of less than 4 ms. When a grid outage occurs, the system can quickly transfer supply to the backup output as long as sufficient energy is available in the battery or from PV generation.

3-in-1 port for generator, smart loads, and PV inverter

The ES Uniq series includes a multifunction 3-in-1 port that expands installation configuration options. This port can be used to integrate a generator, manage smart loads, or connect a compatible grid-tied PV inverter, depending on the system design.

For the GW10K-ES-C10 model, the generator input supports a rated apparent power of 10 kVA and a maximum apparent power of 11 kVA.

Grid-tied and off-grid operation

The inverter can be used both in grid-connected installations and in off-grid configurations. This flexibility makes it possible to create systems focused on standard self-consumption, installations with storage and backup, or solutions aimed at increasing the home’s energy independence.

The ES Uniq series also supports microgrid operation, allowing coordination with other PV equipment to manage different generation and consumption sources.

Up to 6 inverters in parallel

GoodWe allows up to 6 compatible ES Uniq inverters to be connected in parallel in both grid-connected and off-grid operation. This feature makes it easier to create scalable installations and expand available power later as energy needs grow.

Maximum efficiency of 97.6%

The GW10K-ES-C10 achieves a maximum efficiency of 97.6% and a European efficiency of 96.2%. Maximum battery-to-grid efficiency is 95.5%, while MPPT tracking efficiency reaches 99.9%.

These performance figures help make efficient use of both the energy generated by the PV modules and the energy stored in the batteries.
