3. High-Capacity 32kW Solar Input

One of the key features of the IVGM20KLP3G1 is its stated maximum solar PV input capacity of 32,000W.

The integrated MPPT system is rated at 16,000W per MPPT channel, giving a combined capacity of 32,000W. This allows the inverter to support a substantial solar array when correctly designed and installed.

The inverter can be configured with solar modules rated between 550W and 700W, provided the voltage, current, and power limits specified by the manufacturer are respected.

For example, using 48 solar panels rated at 635W each gives:

• Number of solar panels: 48
• Wattage per panel: 635W
• Total installed solar capacity: 48 × 635W
• Total solar array capacity: 30,480W (30.48kWp)

This configuration provides a substantial solar generation capacity for daytime consumption, battery charging, and other supported operating requirements.

Actual energy production will depend on sunshine availability, panel orientation, shading, temperature, installation conditions, and system configuration.

4. Dual MPPT Technology for Efficient Solar Generation

The inverter incorporates two Maximum Power Point Tracking (MPPT) channels, each rated at 16,000W according to the supplied specifications.

MPPT technology continuously adjusts the electrical operating point of the solar array to extract available power efficiently as sunlight and panel temperatures change.

The dual-MPPT arrangement can provide greater flexibility when designing a solar array with different roof orientations or separate panel groups, provided the electrical characteristics of each string meet the inverter’s requirements.

The four PV input ports facilitate solar string connections, but they should not automatically be interpreted as four independent MPPT trackers. The supplied specifications indicate two MPPT channels, so the final string arrangement must follow the manufacturer’s wiring diagram.

Benefits of the MPPT system

• Helps maximise energy harvested from the solar panels.
• Supports efficient solar energy conversion under changing weather conditions.
• Enables a substantial solar array to be connected to the inverter.
• Helps supply daytime electrical loads while supporting battery charging.
• Provides flexibility when arranging solar strings across suitable roof sections or mounting structures.

5. Three-Phase 20kW Power Output

The IVGM20KLP3G1 is designed for applications that require three-phase electrical power.

With a rated active power of 20kW and an apparent power rating of 22KVA, it can support a wide range of electrical equipment when the loads are correctly sized and distributed.

Three-phase power is particularly useful for installations with compatible motors, pumps, workshop equipment, and commercial machinery.

Suitable applications include:

• Commercial buildings and offices.
• Hotels, lodges, and hospitality facilities.
• Workshops and manufacturing premises.
• Agricultural facilities and irrigation systems.
• Water pumping installations.
• Shops, supermarkets, and commercial outlets.
• Residential properties with three-phase electrical connections.
• Small industrial facilities with compatible electrical loads.

Important: The 22KVA rating does not mean that every appliance or motor can be operated simultaneously without limitation. Actual performance depends on the inverter’s continuous output rating, phase-load limits, starting surge capability, power factor, and the electrical requirements of connected equipment. Heavy motor loads must be checked against the manufacturer’s surge specifications.

6. On-Grid and Off-Grid Hybrid Operation

The inverter’s hybrid functionality allows solar generation, battery storage, and a compatible grid or generator supply to be coordinated according to the available operating modes and configuration.

On-grid operation

When configured for grid-connected operation, the inverter can work with the utility supply to manage solar energy and electrical loads. Depending on the selected operating mode, installation requirements, and grid settings, available solar power may be used to supply loads and charge the batteries.

Any export of excess solar electricity to the utility grid depends on the inverter configuration, applicable approvals, and the local electricity provider’s requirements.

Off-grid operation

In off-grid mode, the inverter can provide electricity to supported loads using available solar generation and stored battery energy without relying on the utility grid as the primary source.

This mode can be useful for locations where grid electricity is unavailable, unreliable, or expensive.

Hybrid energy management

The system can be configured to prioritise available energy sources according to supported settings, load requirements, and battery-management parameters.

This flexibility can help users:

• Reduce dependence on utility electricity.
• Make better use of available solar energy.
• Store surplus solar energy for later consumption.
• Maintain power to supported loads during grid interruptions when correctly configured.
• Improve control over energy consumption and operating costs.

The precise switching behaviour and supported combinations of grid, generator, PV, and battery power should be verified against the manufacturer’s manual.

7. Compatibility with a 48V Battery Bank

The inverter operates with a nominal 48V battery system, allowing the installation to incorporate a suitably sized battery bank for energy storage.

A compatible lithium battery bank can store excess solar energy generated during the day and release it when solar production falls, including during the evening and at night.

The actual storage capacity required depends on the property’s energy consumption, desired backup duration, battery discharge limits, and the availability of other energy sources.

Advantages of battery storage

• Provides access to stored solar energy after sunset.
• Supports backup power for selected loads during grid interruptions.
• Helps reduce reliance on grid electricity during periods of low solar generation.
• Improves the utilisation of solar electricity generated during the day.
• Allows the solar system to be designed around the user’s daily energy requirements.

The battery bank must be compatible with the inverter’s voltage, charging-current limits, communication protocol, and battery-management requirements. Lithium batteries should be connected and configured according to the manufacturer’s instructions.

Battery sizing consideration: A 20kW inverter can draw substantial current from a 48V battery bank when supplying high loads. The battery bank must therefore be designed to provide the required continuous discharge current and surge capacity. The installer should calculate battery current requirements and confirm that the combined battery and BMS ratings can support the intended loads.

8. IP65 Protection for Installation Flexibility

The inverter carries an IP65 enclosure protection rating, indicating that its enclosure is dust-tight and protected against water jets under specified test conditions.

This rating offers an advantage in installations where the equipment may be exposed to dust or occasional water splashes from cleaning or weather.

Potential installation locations include appropriately selected utility rooms, commercial premises, workshops, and protected outdoor equipment areas.

For reliable operation, the inverter should still be installed in accordance with the manufacturer’s requirements for temperature, ventilation, mounting orientation, direct sunlight, clearances, and weather exposure.

IP65 protection does not mean the inverter is suitable for immersion in water or for installation in every outdoor environment without additional precautions.

9. Wi-Fi Monitoring and System Management

The supplied configuration includes a Wi-Fi monitoring module, providing a convenient way to monitor system performance where the manufacturer’s monitoring platform and network requirements are supported.

Depending on the monitoring application and inverter configuration, users may be able to access information such as solar generation, battery status, power output, grid operation, and system alarms.

Monitoring advantages

• Convenient access to system operating information.
• Easier tracking of solar generation and energy utilisation.
• Helps identify operating issues and system alerts.
• Supports maintenance and performance checks.
• Improves visibility into the performance of the installed solar system.

Availability of specific monitoring functions depends on the manufacturer’s software, communications setup, internet connection, and inverter firmware.
