GoodWe ES Uniq 5kW Single-Phase LV Hybrid Inverter

GoodWe ES Uniq 5kW Hybrid Inverter

The GoodWe GW5000-ES-C10 is a 5kW single-phase, low-voltage hybrid inverter for residential solar generation, battery backup and intelligent energy management. It combines the solar-array, battery, grid and backup functions required in a modern hybrid system, allowing available energy to be managed through one central inverter platform.

With 5kW rated output power and 5.5kW maximum AC active power, the ES Uniq is suited to properly designed household systems where essential and selected non-essential loads must be supported. As a hybrid inverter, it can use solar power directly, charge a compatible battery bank and supply supported loads according to the system configuration. The final performance of any installation depends on the connected battery capacity, solar-array design, load requirements, switchgear, wiring and programmed operating settings.

Designed for Residential Solar and Backup Applications

The ES Uniq can be used in new residential solar installations, battery-backup systems and upgrades where compatible components are already installed. Typical applications include increasing daytime solar self-consumption, storing excess solar energy for later use, maintaining selected circuits during power interruptions and managing energy from the grid, battery, solar array and a suitably integrated generator.

This is a single-phase inverter. It should be matched to the electrical supply, distribution board and intended backup-load arrangement of the property. Correct load separation remains important: the inverter rating does not mean that every appliance in a home can necessarily operate at the same time during backup operation.

48V Low-Voltage Battery Compatibility

The inverter uses a nominal 48V battery system and supports a battery-voltage range of 40–60V. It is compatible with suitable lithium-ion and lead-acid battery technologies, subject to the battery manufacturer’s approved compatibility, communication and configuration requirements.

Maximum continuous charging and discharging currents are rated at 120A. This allows the inverter to move substantial power into and out of an appropriately sized battery bank. The battery must still be selected according to its own continuous-current limits, usable capacity, battery-management system and the household’s required backup duration. A battery with insufficient discharge capability can restrict the usable output of the overall system even when the inverter itself is rated for 5kW.

CAN communication is provided for compatible battery-management systems. Correct BMS communication allows a supported lithium battery and inverter to exchange operating information such as charge limits and battery status. Battery compatibility and communication settings should always be confirmed before installation.

10kW PV Input with Dual MPPT Control

The GoodWe ES Uniq accepts up to 10kW of PV input power. This generous PV allowance gives system designers flexibility when sizing the solar array for stronger morning, afternoon or seasonal production. Maximum PV input power should not be confused with AC output power: the connected array must still remain within every voltage and current limit, while usable power is governed by operating conditions, battery demand, household consumption and the inverter’s output capability.

Two independent MPPT trackers are included, with one string connection per MPPT. Dual MPPT control is useful where panels must be divided between two roof orientations, pitches or solar-production profiles. Each tracker can manage its connected string independently, helping the inverter extract available energy when the two arrays experience different operating conditions.

The MPPT operating range is 60–550V, the PV start-up voltage is 58V and the maximum PV input voltage is 600V. Maximum input current is 20A per MPPT and maximum short-circuit current is 26A per MPPT. These limits must be checked against the selected panel’s open-circuit voltage, operating voltage, current and temperature-adjusted string calculations. The 10kW figure alone must never be used to determine the number of panels.

Less-Than-4ms Backup Switching

The specified backup switching time is less than 4ms. This rapid transition is designed to reduce interruption to supported circuits when grid power fails. It is particularly valuable for everyday household electronics and essential loads connected to the inverter’s correctly configured backup supply.

Backup performance depends on the instantaneous load, available battery power, battery state of charge and installation design. Appliances with high starting currents or large heating loads must be assessed before they are placed on the backup circuit. Sensitive equipment should always be evaluated according to its own power-quality and continuity requirements.

Generator and Smart-Load Functionality

Generator and smart-load functionality gives the system additional flexibility beyond normal solar, battery and grid operation. In an appropriate design, these functions can support generator integration or controlled use of selected loads according to the configured operating strategy.

The required mode, switching arrangement, protection equipment and control settings must be determined during system design. Generator compatibility, earthing, neutral management and changeover requirements must also be verified by the responsible installer. Smart-load functionality does not remove the need to confirm the appliance rating and the amount of power available at the time the load is activated.

High Conversion and MPPT Efficiency

The inverter offers a maximum efficiency of 97.6%, European efficiency of 96.2%, maximum battery-to-AC efficiency of 95.5% and MPPT efficiency of 99.9%. These figures describe performance across different power-conversion stages and demonstrate the inverter’s ability to convert and manage energy efficiently within its specified operating range.

Actual system efficiency will also be influenced by cable losses, temperature, solar-panel conditions, battery efficiency, battery state of charge and the amount of energy passing through each conversion stage. Professional equipment selection and correct conductor sizing remain essential to achieving reliable real-world performance.

Monitoring and Communication Options

The ES Uniq provides an LCD interface together with WLAN and app-based monitoring. Communication options include RS485, Wi-Fi, LAN and Bluetooth, while supported protocols include Modbus-RTU and Modbus-TCP. These options allow access to system information and provide flexibility for compatible monitoring or energy-management integrations.

Available monitoring functions can depend on the installed communication accessories, network connection, firmware, platform availability and final commissioning. BMS communication is handled through CAN for supported battery systems.

IP66 Protection and Natural-Convection Cooling

An IP66 enclosure provides strong protection against dust and water ingress when the inverter is installed in accordance with GoodWe’s requirements. Natural-convection cooling removes the need for a cooling fan, reducing fan noise and eliminating a moving cooling component from normal operation.

The specified operating-temperature range is -35°C to +60°C and the maximum operating altitude is 3000m. The wall-mounted unit measures 560 × 415 × 204mm and weighs 15.5kg. Installation position, clearances, ventilation, direct environmental exposure and structural support must comply with the manufacturer’s instructions.

Parallel Expansion for Larger Requirements

Up to six compatible inverters can operate in parallel. This provides a pathway for increasing system capacity where the electrical design, communications, battery bank and protection equipment have been planned for parallel operation. Parallel expansion is an engineered configuration and should not be treated as a simple plug-and-play addition to an existing installation.
