Growatt WIT-25K-HU 25kW Three Phase Hybrid Solar Inverter with Battery Backup and 37.5kW PV Input

Growatt WIT-25K-HU 25kW Three-Phase Hybrid Solar Inverter

The Growatt WIT-25K-HU 25kW Three-Phase Hybrid Solar Inverter is designed for solar installations that require high power capacity, battery energy storage, grid integration, and backup output. With a nominal AC output power of 25kW and a maximum PV input power of 37.5kW, it is suitable for consideration in commercial facilities and larger residential projects.

Its three-phase configuration, dual MPPT trackers, high-voltage battery compatibility, and EPS backup output make it an option for projects requiring coordinated solar generation and energy storage.

25kW Three-Phase Power Output

The Growatt WIT-25K-HU has a nominal AC output power of 25,000W and a maximum AC apparent power of 27,500VA, according to the supplied specifications.

Its nominal AC voltage is 230V/400V with a three-phase 3L/N/PE configuration. This makes it suitable for compatible three-phase electrical installations, subject to local grid requirements and professional system design.

Potential applications include commercial premises, offices, larger residential properties, and other installations with compatible three-phase electrical infrastructure.

Maximum 37.5kW Solar PV Input

The inverter supports a specified maximum PV input power of 37.5kW. This provides flexibility when designing a solar array around a 25kW AC inverter.

The listed maximum DC voltage is 1,100V, with an MPPT voltage range of 180–1,000V and a start-up voltage of 200V. It includes two MPPT trackers and two strings per MPPT.

Solar panel strings must be configured carefully to remain within the inverter's maximum voltage, operating current, and short-circuit current limits. A qualified solar designer should verify the array configuration using the panel datasheets and local environmental conditions.

Dual MPPT for Solar Energy Optimization

The Growatt WIT-25K-HU features two Maximum Power Point Tracking (MPPT) trackers. MPPT technology helps the inverter adjust its operating point to extract available power from connected solar panels.

The two MPPT trackers can provide flexibility when designing compatible solar panel strings. The final string layout must follow the manufacturer's input-current and voltage specifications.

High-Voltage Battery Energy Storage

The inverter supports lithium-ion and lead-acid batteries, according to the supplied specifications. Its listed battery voltage range is 180–800V, with a maximum charge/discharge current of 50A and maximum charge/discharge power of 25kW.

Battery compatibility must be checked carefully before purchase. Confirm the supported battery model, voltage range, communication protocol, and charging requirements to ensure safe and reliable operation.

The battery capacity required for backup depends on the connected load and desired backup duration. A 25kW inverter rating does not by itself determine how long a battery system can supply electricity.

EPS Backup Output with Fast Switchover

The Growatt WIT-25K-HU includes an EPS/backup output with a specified nominal power of 25kW and maximum apparent power of 27,500VA.

The supplied specifications state an automatic switchover time of less than 10ms. Actual backup performance depends on operating conditions, battery availability, load characteristics, and the system configuration.

Sensitive equipment and high-starting-current loads should be assessed before installation to ensure they are compatible with the backup output.

High Efficiency and Intelligent Cooling

The inverter has a specified maximum efficiency of 98.5%, European efficiency of 98.0%, and MPPT efficiency of 99.9%.

Its smart forced-air cooling system helps manage operating temperature. The listed operating temperature range is −25°C to +60°C, and the noise emission is below 40dB(A), according to the supplied specifications.

Actual efficiency and thermal performance depend on installation conditions, ambient temperature, load, and solar input.

IP65 Protection and Communication Interfaces

The IP65 protection rating provides protection against dust ingress and water jets under defined test conditions. Installation must still follow manufacturer requirements for mounting, clearance, and environmental exposure.

The inverter includes an LED indicator, integrated LCD, RS485, CAN, and USB interfaces. Wi-Fi/GPRS connectivity is listed as optional, so confirm whether additional communication accessories are required for remote monitoring.

Suitable Applications in Bangladesh

The Growatt WIT-25K-HU can be considered for appropriately designed solar projects in Bangladesh, including:

- Commercial buildings and business premises

- Offices and institutional facilities

- Large residential solar installations with three-phase supply

- Solar systems requiring compatible high-voltage battery storage

- Projects requiring both grid-connected operation and backup output

Before installation, verify the local grid connection requirements, applicable approvals, export or net-metering eligibility, and protective-device requirements. A qualified installer should design the solar array, battery bank, cables, earthing, and protection systems.

5-Year Standard Warranty

The supplied specifications list a 5-year standard warranty, with an option to extend it. Confirm the warranty provider, coverage, exclusions, and extension conditions with the seller before purchasing.
