GoodWe 15kW ET G2 Hybrid Inverter Overview

The GoodWe 15kW ET G2 Hybrid Inverter combines solar generation, high-voltage battery storage, grid power and backup output in one three-phase energy management system. The GW15K-ET-20 delivers a 15kW nominal AC output and accepts up to 24kW of PV input, giving system designers room to build a relatively high-capacity solar array around the inverter.

Its 500V nominal battery architecture is designed for Li-Ion batteries, with a battery operating range of 150V to 720V. On the solar side, the inverter provides 3 MPPT trackers, a 120V–850V MPPT operating range, and up to 16A input current per MPPT.

For backup applications, the inverter provides a 15kVA nominal backup output and can reach up to 18kVA for 60 seconds when the required PV and battery power is available. The combination makes it suitable for buyers looking for a 15kW three-phase hybrid inverter for larger homes, high-consumption properties and selected commercial installations.

Why This Hybrid Inverter Stands Out

High PV Input Capacity

The inverter supports up to 24kW maximum PV input power against its 15kW AC rated output. This gives the system designer substantial DC-side capacity for solar generation.

The PV array should still be designed according to the actual Voc, Isc, MPPT voltage range, input current and temperature conditions rather than simply matching the array to the 24kW maximum input figure.

Three MPPT Trackers

The three MPPTs provide more flexibility in cases where the solar panels are installed on different roof orientations or in various string configurations. Each MPPT can support an input current of up to 16 amperes and a short-circuit current of up to 24 amperes.

It is therefore important to get string planning right, especially when using modern high-current solar modules.

Fast Backup Switching

The UPS-level backup switching offered by the inverter takes less than 10 milliseconds. This is especially useful in cases where certain loads require a quick switch to backup power when the grid fails.

The true backup performance will still be influenced by the loads that are connected, by the amount of battery available and by the entire system design.

Parallel Expansion

The ET G2 platform can have up to six units connected in parallel, which enables larger systems to be expanded whenever the installation needs more output capacity.

The design of the parallel system should be carried out in accordance with the inverter’s electrical configuration and installation requirements.

IP66 Outdoor Protection

With an IP66 ingress protection rating, the inverter has a strong enclosure protection level for installations where protection against dust and water ingress is important. Proper mounting location, ventilation and installation practice remain important, especially in Pakistan’s hot and dusty conditions.

Best For

The GoodWe 15kW hybrid inverter is a strong option for:

• Three-phase homes with higher electricity consumption
• Large residential solar systems requiring battery backup
• Properties with significant daytime solar loads
• Users planning a high-voltage lithium-ion battery system
• Installations affected by load shedding
• Selected commercial applications requiring solar, grid and battery integration
• Systems where future parallel expansion may be required
• Solar projects requiring a high PV-to-inverter capacity ratio

Not Ideal For

This inverter may not be the right choice for:

• A single-phase electrical installation
• Buyers specifically looking for a low-voltage battery inverter
• Systems requiring unsupported battery chemistry or incompatible BMS communication
• Very small solar installations where a 15kW inverter would be unnecessarily large
• PV designs exceeding the inverter’s voltage, current or input-power limits
• Buyers who only need a basic on-grid inverter and have no requirement for battery storage or backup

Solar PV Input and MPPT Performance

The maximum PV input capacity of the GoodWe 15kW ET G2 is 24kW, its maximum DC input voltage is 1000V and the MPPT operating voltage range is from 120V to 850V; the PV startup voltage is 150V.

The inverter is fitted with three MPPT trackers, each associated with one string. Each MPPT has a maximum input current of 16 amperes and a maximum short-circuit current of 24 amperes.

When installing the systems, technicians should take the limits into account if they are to choose the modules and design the strings; before the final installation, the panel’s Voc and Isc, the operating temperature, the string length and the inverter’s MPPT range should all be checked.

The inverter also has an MPPT efficiency of 99.5%, which helps the system to effectively track the available solar power under appropriate operating conditions.

Battery Compatibility and Energy Storage

The device known as GW15K-ET-20 is based on a high-voltage lithium-ion battery design.

Key battery parameters include:

• Battery Type: Li-Ion
• Nominal Battery Voltage: 500V
• Battery Voltage Range: 150V–720V
• Battery Startup Voltage: 150V
• Battery Inputs: 1
• Maximum Continuous Charging Current: 40A
• Maximum Continuous Discharging Current: 40A
• Maximum Charging Power: 24kW
• Maximum Discharging Power: 16.5kW
• BMS Communication: RS485 and CAN

Before buying a battery it is necessary to check specifically which brand and model it is compatible with since compatibility in terms of voltage alone is not enough to ensure complete compatibility; the battery’s communication protocol, BMS configuration and system requirements must also match.

For buyers searching for goodwe 15kw battery price in pakistan, it is important to distinguish between the inverter and the separate high-voltage battery required for the complete storage system.

Backup Power and Load-Shedding Performance

The inverter has a nominal backup output of 15 kVA and, when running without grid power, can reach a maximum apparent power of 18 kVA for a period of 60 seconds on the condition that adequate PV and battery power are available.

The fact that it has a backup switching time of less than 10 milliseconds is useful in cases where certain loads need to switch over quickly during power outages.

When installing a practical system in Pakistan, the backup circuits should be planned in accordance with the real load profile; individual assessments should be made of high-power appliances, motors, pumps, air conditioners and other heavy loads rather than assuming that all the connected loads can operate at full capacity simultaneously.

Enough battery capacity, the right protection equipment, proper cable size, and professional installation are also important for reliable backup operation.

Parallel Operation and System Expansion

The ET G2 Series supports parallel connection of up to 6 units. This provides an expansion path for installations where one inverter’s output capacity may not be sufficient for the long-term requirement.

Parallel operation should be based on the entire electrical system, including the inverter configuration, the battery architecture, the protection equipment and the load requirements.

This feature is especially useful in the case of large projects since the energy demand might increase over time.

Smart Load Control and Monitoring

The inverter includes an integrated dry contact for external loads, supporting smart load-control applications. It also provides peak shaving functionality.

For monitoring and communication, the system supports:

• WLAN + APP
• Wi-Fi
• Bluetooth
• LAN
• RS485
• CAN
• RS485 meter communication
• 4G optional portal communication

The network interfaces of the BMS enable the inverter to communicate with a compatible battery management system, and they also offer the possibility of carrying out system monitoring and management.

Hybrid Inverter Use in Pakistan

For Pakistani solar users, a three-phase hybrid inverter can be useful where solar generation, grid electricity and battery backup need to work together.

In the day solar energy can be used to meet the demand from active loads while the surplus generation can be directed to battery charging, this depending on the system configuration and the operating conditions. When the grid fails the backup output can support certain loads provided that there is sufficient battery energy available.

The <10ms switching capability is particularly relevant for areas experiencing frequent grid interruptions. At the same time, backup reliability depends on correct battery sizing, load selection, wiring, protection devices and installation quality.

Pakistan’s summer temperatures also make installation conditions important. Although the inverter has an operating temperature range of -35°C to +60°C, it should still be installed in a suitable location with proper ventilation and protection from unnecessary direct heat and environmental exposure.
