Growatt 25KW LV Three Phase Hybrid Inverter

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

The Growatt 25KW WIT 25K-HU LV Three Phase Hybrid Inverter coordinates solar generation, low-voltage battery storage, grid supply, generator input and backup power. Its 25,000W three-phase output suits large homes and commercial properties whose connected loads have been checked against the inverter rating.

This growatt 25kw lv inverter works with 40-60V lithium-ion or lead-acid batteries and accepts up to 50,000W of recommended PV power at module STC. Its combination of high solar-input capacity, powerful battery charging, fast backup transfer and generator support makes it suitable for professionally designed three-phase hybrid systems.

Why This Hybrid Inverter Stands Out

High PV Input Capacity

Up to 50,000W of recommended PV power gives system designers room for strong daytime solar generation. The array must remain within the 1,000V maximum input voltage, 150-850V MPPT operating range and applicable current limits.

High Battery Charge and Discharge Current

A maximum charging and discharging current of 420A supports a properly sized low-voltage battery bank. The battery modules, cables, protection equipment and BMS must all match the planned operating current.

Strong Backup Capability

The inverter supports 110% continuous AC overloading capacity. Its 25,000W backup output can provide maximum apparent power of twice the rated output for 10 seconds.

Transfer from on-grid to off-grid operation takes less than 10ms. UPS function, black start and support for 100% three-phase unbalanced loading further strengthen its backup performance. This is fast transfer, but it should not be treated as a guarantee of zero interruption for every connected device.

Generator Input and Smart Load Control

An integrated generator port and smart load control provide additional energy-management flexibility. Generator capacity, wiring, phase arrangement and operating settings must be finalized by a qualified installer.

Best For

• Large homes and commercial premises with a suitable three-phase connection
• High-PV systems designed around two MPPT trackers
• Properties affected by load shedding that require three-phase backup power
• Users planning a compatible 51.2V lithium-ion or lead-acid battery bank
• Installations requiring generator input, black start or smart load management
• Businesses seeking to improve solar self-consumption while retaining grid and battery support

Not Ideal For

• Single-phase sites without a suitable three-phase electrical system
• High-voltage battery banks, because this model operates within a 40-60V battery range
• PV strings exceeding the permitted voltage, input-current or short-circuit-current limits
• Buyers who only require conventional on-grid operation without battery storage
• Loads exceeding the inverter’s continuous output limits
• Systems planned without a professional load, battery and electrical-protection assessment

Solar PV Input and MPPT Performance

The WIT 25K-HU accepts up to 50,000W of recommended PV power at module STC. Its maximum DC input voltage is 1,000V, start voltage is 180V and nominal PV voltage is 625V.

Two MPPT trackers operate across a 150-850V range. This arrangement allows two independently designed solar groups where roof orientation, shading conditions or string layout require separation.

Each MPPT accepts up to 40A input current and 50A short-circuit current. Two PV strings can be connected to each tracker, with maximum string current reaching 20A.

Final module selection and string quantities must be checked using module Voc, Isc, temperature correction and every applicable MPPT limit. Remaining within the recommended PV wattage alone does not make a string design safe or compatible.

Battery Compatibility and Energy Storage

The inverter supports lithium-ion and lead-acid batteries across a 40-60V operating range, with 51.2V recommended. Its maximum charging and discharging current is 420A.

RS485 and CAN communication support BMS integration with compatible lithium batteries. The exact battery model, communication protocol and approved connection method should be confirmed before purchase.

Battery capacity should be selected according to the required backup load, expected runtime, allowed depth of discharge and battery-current capability. A larger battery does not automatically provide better performance unless its BMS, current rating and communication protocol match the inverter.

Backup Power and Load-Shedding Performance

The backup circuit provides 25,000W rated AC output at three-phase voltage options of 220V/380V, 230V/400V or 240V/415V. Nominal output frequency is 50/60Hz.

Maximum backup output current is 75.76A, while total harmonic voltage distortion is rated at 3% with a linear load. The backup output can support 100% three-phase unbalanced loading within its electrical limits.

Transfer from on-grid to off-grid operation takes less than 10ms. Actual backup time depends on usable battery energy, connected loads, inverter settings, battery condition and operating temperature.

Essential and non-essential circuits should be separated during system planning. Heavy motors, compressors, pumps and other high-starting-current loads require additional assessment before connection to the backup output.

Generator Integration and Smart Load Control

The integrated generator input allows solar, battery, grid and generator supply to work within one coordinated energy system. Smart load control can help manage selected loads according to operating priorities.

A generator must be matched for voltage, frequency, phase, starting behaviour and expected load. Incorrect generator selection or unstable generator output may cause protection trips or unreliable operation.

Monitoring and Communication

An OLED/LED display and app support provide local and remote visibility of system operation. RS485, USB, Wi-Fi and LAN interfaces support monitoring and communication requirements.

CAN and RS485 are also available for compatible battery communication. Reliable networking and correct commissioning are required for dependable remote monitoring and operating data.

Protection Features

The inverter includes PV reverse-polarity protection, a 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. An AFCI function is available as an optional feature.

Recommended Solar System Size

The inverter’s 25KW rated output and its 50,000W recommended PV allowance represent different limits. The appropriate PV array may be lower depending on roof space, module characteristics, export regulations, daytime consumption, battery-charging requirements and local installation conditions.

Every design must keep string Voc below 1,000V after cold-temperature correction, maintain operating voltage within the 150-850V MPPT range and respect the 40A input-current and 50A short-circuit-current limits for each tracker.

Suitable DC isolation, surge protection, earthing, cable sizing and ventilation should form part of the final engineering plan.

Hybrid Inverter Use in Pakistan

For Pakistan’s load-shedding conditions, this inverter can supply daytime loads from available solar power, store energy in a compatible battery and run selected circuits from its backup output when the grid fails.

Generator integration provides an additional supply option during longer outages or periods of low solar generation. The system can also improve solar self-consumption by coordinating PV production, battery charging and property loads.

Installers should consider phase loading, high ambient temperatures, grid-voltage variation, dust exposure, earthing quality and the clearance required for smart air cooling. IP66 protection supports demanding environments, but appropriate placement and routine maintenance remain important.
