Off-Grid IGBT Solar Inverter (5kW / 30kW, 3-30kW Series)

The GS-OG5K-IGBT belongs to our heavy-duty off-grid inverter series (3-30kW) built on Mitsubishi IGBT power modules. IGBTs handle high surge currents and inductive loads – water pumps, compressors, welding equipment – that challenge ordinary MOSFET inverters, making this cabinet-style unit a favourite for farms, workshops and telecommunication sites. Larger 30kW models with a 192VDC high-voltage battery bus serve villas, small factories, hotels and farms running heavy motor loads around the clock.

Key Features

• Mitsubishi IGBT power stage: handles high surge currents and heavy inductive loads.
• Galvanic isolation: transformer-based output for clean, safe pure sine power.
• High efficiency: over 90% system efficiency from battery to AC output.
• Service-friendly cabinet: floor-standing enclosure with wheels for easy positioning and maintenance.
• Parallel operation: supports paralleling for larger loads, with 96V/192V DC options on bigger models.
• Comprehensive protection: overload, short-circuit, over-voltage, under-voltage and over-temperature.

Typical Applications

Farms, workshops and telecom sites running pumps, compressors and power tools – and, at 30kW, villas, small factories, hotels and farms with heavy inductive loads. The series bridges the gap between residential inverters and industrial three-phase systems.

Common Pain Points We Solve

• Motors that won’t start: Mitsubishi IGBT modules deliver the surge capacity to start pumps, compressors and welders that stall ordinary inverters.
• Harsh site conditions: transformer-based galvanic isolation and a rugged floor cabinet tolerate dusty workshops and farm environments.
• Remote maintenance: modular internal layout and wheeled cabinet simplify servicing, with remote engineering support from our factory team.
• Growing loads: parallel operation lets you add capacity later instead of replacing the whole inverter.
