Growatt 25KW LV Three Phase Hybrid Inverter

Growatt 25KW WIT 25K-HU LV Three Phase Hybrid Inverter Overview

The Growatt 25KW WIT 25K-HU combines solar generation, battery storage and grid power in one three-phase hybrid inverter. Its 25kW rated AC output makes it suitable for systems where substantial daytime solar generation and battery-backed loads are required.

The inverter supports low-voltage batteries from 40V to 60V, with 51.2V recommended battery voltage. It can work with both lithium-ion and lead-acid batteries, while RS485/CAN communication provides the required BMS communication interface for compatible battery systems.

With regard to solar input, the inverter can handle a maximum recommended PV power of 50 kW, which enables a large solar array to be connected to the 25 kW AC inverter. The system also provides for grid operation, battery charging and discharging, powering of backup loads, generator input, and smart load control.

Why This Hybrid Inverter Stands Out

High PV Input Capacity

The Growatt 25KW hybrid inverter supports up to 50kW recommended PV power for module STC, giving system designers considerable flexibility when building a high-PV solar installation.

High Battery Charging and Discharging Current

With up to 420A maximum charging and discharging current, the inverter is designed for substantial low-voltage battery energy storage applications.

Fast Backup Switching

The on/off-grid transfer time is less than 10ms, supporting fast transition to backup operation when the grid supply is unavailable.

Generator and Smart Load Support

The inverter integrates generator input and smart load control, providing additional flexibility for systems that use generator backup or controlled high-power loads.

Outdoor-Ready Protection

The inverter is designed for harsh installation conditions since it has an IP66 rating, features smart air cooling, and can operate within a temperature range of -30°C to +60°C; however, derating must be done when the temperature exceedsing must be done when the temperature exceedsing must be done when the temperature exceeds 45°C.

Best For

The Growatt 25KW LV Three Phase Hybrid Inverter is suitable for:

• Commercial and large residential solar systems
• Three-phase properties requiring battery backup
• Systems using low-voltage lithium-ion batteries
• Solar installations with high PV capacity
• Sites affected by load shedding
• Applications requiring generator integration
• Systems requiring smart load management
• Users who need both grid-connected and backup operation

Not Ideal For

This inverter may not be suitable where:

• The battery system which is required functions outside the voltage range of 40 to 60 volts.
• A high-voltage battery structure is needed for the installation.
• The amount of power that is required from the inverter goes beyond the figure stated for its output.
• The voltage, current, or recommended power of the PV system is more than the allowed amount.
• The system should use a single-phase inverter not a three-phase one.

Solar PV Input and MPPT Performance

The Growatt 25KW WIT 25K-HU provides 2 MPPT trackers, with 2 PV strings per MPPT. The maximum input voltage is 1000V, while the MPPT voltage range is 150V–850V.

The inverter has a 180V startup voltage, a 625V nominal PV voltage, and supports up to 40A input current per MPPT tracker. Maximum short-circuit current is 50A per MPPT tracker.

The maximum recommended PV power is 50kW for module STC. This provides flexibility for designing a larger PV array around a 25kW AC inverter.

Proper string design should remain within the inverter’s specified Voc, Isc, MPPT voltage and input-current limits, with temperature correction applied to PV voltage calculations.

Battery Compatibility and Energy Storage

The inverter uses a low-voltage battery architecture with a supported battery voltage range of 40–60V and a recommended battery voltage of 51.2V.

It supports:

• Lithium-ion batteries
• Lead-acid batteries
• Up to 420A maximum charging current
• Up to 420A maximum discharging current
• RS485/CAN BMS communication

For lithium battery installations, the selected battery must be electrically compatible and provide the required BMS communication. Battery voltage, current capability and communication compatibility should be checked before installation.

Backup Power and Load-Shedding Performance

The Growatt WIT 25K-HU supports UPS functionality and provides <10ms on/off-grid transfer time. This makes it suitable for installations where important loads require rapid transition to backup power.

The inverter has a 25kW rated AC output and can provide up to 2 times rated power for 10 seconds as maximum AC apparent power according to its specified operating capability.

Battery capacity and battery discharge capability should be selected according to the actual backup load. High-power loads may require appropriate battery sizing to maintain the required backup performance.

Generator and Smart Load Operation

The inverter integrates generator input and smart load control, allowing these functions to be incorporated into suitable hybrid energy systems.

Generator integration can provide an additional energy source when solar generation and battery storage are insufficient. Smart load control can also be used for managing selected loads according to the system configuration.

Monitoring and Communication

The inverter provides multiple communication and monitoring interfaces, including:

• Wi-Fi/LAN
• RS485
• USB
• CAN
• APP monitoring
• OLED/LED display

These communication options support system monitoring, configuration and battery BMS communication where applicable.

Protection Features

The inverter includes PV reverse polarity protection, DC switch, Type II DC/AC surge protection, insulation resistance monitoring, residual-current monitoring, AC short-circuit protection, ground fault monitoring, grid monitoring, string monitoring and anti-islanding protection. AFCI function is optional.

Recommended Solar System Size

The 25kW AC rating and 50kW recommended PV power are different system-design values. The inverter can therefore be paired with a PV array larger than its AC output rating, provided the complete PV design remains within the inverter’s electrical limits.

Final system design should consider:

• PV string Voc
• PV string Isc
• MPPT voltage range
• MPPT current limit
• Temperature-related voltage changes
• Number of strings per MPPT
• Local installation conditions

The final PV configuration should be designed according to the inverter’s permitted electrical parameters rather than using the AC rating alone.

Hybrid Inverter Use in Pakistan

For Pakistan’s solar market, the Growatt 25KW hybrid inverter can support solar self-consumption, battery storage and backup operation in three-phase installations. Its low-voltage battery architecture can be useful for systems designed around 48V/51.2V-class battery storage.

The UPS feature of the inverter, its fast transfer time, the generator input, and the smart load control all offer flexibility in locations where the availability of the grid and the amount of load vary during the day.

Correct installation should also account for heat, ventilation, electrical protection, PV string configuration and battery compatibility, particularly in high-temperature conditions.
