22kVA / 20kW Felicity IVGM20KLP3G1 48V Three-Phase On/Off-Grid IP65 Hybrid Inverter

The 22kVA / 20kW Felicity IVGM20KLP3G1 Hybrid Inverter is a high-capacity three-phase solar power platform specifically suited to installations requiring considerably more power than standard residential hybrid inverters. It combines 20kW rated power, 48V battery architecture, three-phase operation, on/off-grid functionality and an IP65-rated enclosure.

Its 20kW output makes the IVGM20KLP3G1 particularly relevant to commercial properties, workshops, large three-phase homes and other installations where multiple electrical loads need to operate simultaneously.

Compared with the 16kW Felicity IVGM16KLP3G, this model provides 4kW additional nominal output capacity – a 25% increase. This makes it a clear step up where the calculated three-phase load requires more capacity than the 16kW model can provide.

The combination of on/off-grid operation and 48V battery support also allows the inverter to form the centre of a properly engineered system integrating solar generation, battery storage and utility power.

20kW High-Output Advantage

The 20kW rated power is the defining characteristic of this Felicity inverter.

At this capacity, the system moves well beyond basic backup for lights and electronics. It is intended for properties where considerably larger groups of compatible loads need to be supplied.

Depending on professional load calculations, potential applications can include:

🏢 Multiple Commercial Circuits

💡 Extensive Lighting

💻 Computers & Office Equipment

📡 Networking & Communication Systems

🧊 Compatible Refrigeration

⚙️ Selected Three-Phase Equipment

🔌 Higher-Demand Electrical Loads

🏡 Multiple Residential Circuits

Actual equipment compatibility must be established from operating power, starting demand and phase requirements.

22kVA / 20kW Rating Advantage

This Felicity inverter carries both a 22kVA apparent-power rating and a 20kW active-power rating.

These values describe different electrical quantities:

22kVA → Apparent Power

20kW → Active Power

Keeping both specifications in the product description gives customers and installers a clearer representation of the inverter’s stated capacity.

Three-Phase Power Advantage

The IVGM20KLP3G1 is specifically a three-phase inverter, making it particularly suitable for properties with three-phase electrical distribution.

Rather than treating a 20kW system simply as a larger residential inverter, the three-phase architecture positions this model for applications such as:

🏢 Commercial Buildings

🏭 Workshops

🏪 Retail Premises

🏡 Large Three-Phase Homes

☀️ Commercial Solar Systems

⚙️ Compatible Three-Phase Loads

Correct phase balancing and site electrical design become particularly important in installations of this size.

20kW vs 16kW Felicity Three-Phase

The IVGM20KLP3G1 provides a clear capacity step above the 16kW IVGM16KLP3G.

This makes the 20kW version especially relevant where a load assessment shows that 16kW would provide insufficient simultaneous power capacity.

48V High-Power Battery Advantage

The inverter operates on a 48V battery platform, but a 20kW inverter requires careful battery engineering.

At high output, the battery system must be capable of supplying substantial DC power. Therefore, simply selecting a battery because it is described as 48V is not sufficient.

The battery system must be evaluated for:

• Compatible operating-voltage range
• Continuous discharge capability
• Required kWh capacity
• Maximum permitted charging current
• Backup-duration target
• Battery communication requirements
• DC cable-current capacity
• Required DC protection

This is particularly important when selecting between 5.12kWh, 10.24kWh, 15.36kWh or larger battery-storage configurations.

On/Off-Grid Advantage

The on/off-grid capability gives the IVGM20KLP3G1 flexibility for advanced solar installations.

☀️ On-Grid
Allows the inverter to operate within an appropriately designed grid-connected solar installation.

🔋 Off-Grid / Battery-Supported
Allows compatible battery storage and solar generation to support loads according to the inverter’s available operating modes.

This allows a properly designed installation to integrate:

☀️ Solar + 🔋 Battery + ⚡ Grid + 🏢 Three-Phase Loads

Grid-connected installation must comply with applicable utility and electrical requirements.

IP65 Protection Advantage

The inverter’s IP65 rating provides defined environmental protection:

6 – Dust-tight under the relevant IP test conditions.

5 – Protected against water jets under the relevant IP test conditions.

This is particularly useful for commercial and solar installations where dust and environmental exposure need to be considered.

IP65 does not mean the inverter can be submerged or installed without observing Felicity’s requirements for ventilation, mounting, temperature and environmental exposure.

Commercial Solar Advantage

The 20kW three-phase architecture gives the IVGM20KLP3G1 a particularly strong commercial position.

Potential installations include appropriately sized:

🏢 Office Buildings

🏪 Retail Premises

🏭 Workshops

💻 IT & Computer Systems

📡 Communication Equipment

💡 Commercial Lighting

🧊 Compatible Refrigeration

⚙️ Selected Three-Phase Equipment

For commercial installations, an actual site load survey is essential because total kW alone does not show how loads are distributed across the phases.

Large Three-Phase Home Advantage

For large homes operating on a three-phase electrical supply, the 20kW capacity provides greater flexibility for integrating solar and battery storage across a substantial electrical installation.

Rather than designing the system only around emergency circuits, the higher inverter capacity can accommodate a broader group of appropriately selected loads.

However, high-consumption appliances should still be individually assessed rather than assuming every appliance can operate simultaneously.

Solar + Battery + Grid Integration

A typical system architecture can broadly be represented as:

☀️ Solar PV → ⚡ Felicity IVGM20KLP3G1 ↔ 🔋 48V Battery Storage

⚡ Utility Grid ↔ Hybrid Inverter → 🏢 Three-Phase Distribution

This allows the inverter to act as the central power-conversion component between compatible PV generation, battery storage, grid supply and three-phase loads.

The supplied information does not specify maximum PV input, PV voltage range, MPPT configuration or charging current, so these specifications should be confirmed before solar-array design.

Battery Storage for a 20kW Inverter

The inverter’s 20kW rating describes power, not backup duration.

Battery kWh describes stored energy.

For example:

⚡ 20kW Inverter → determines available power capability

🔋 15.36kWh Battery → determines nominal stored energy

A larger battery capacity can increase available stored energy, but it does not increase the inverter above 20kW.

Likewise, a 20kW inverter paired with insufficient battery capacity or discharge capability will not create a properly balanced high-power system.

Applications / Use Cases

🏢 Commercial Buildings – high-capacity three-phase solar and battery installations.

🏭 Workshops – suitable for appropriately calculated workshop and compatible three-phase loads.

🏡 Large Three-Phase Homes – substantial solar and backup platform for larger residential properties.

🏪 Retail & Business Premises – supports appropriately sized commercial electrical systems.

☀️ On/Off-Grid Solar Systems – combines solar, battery storage and utility power.

🔋 High-Capacity Battery Backup – suitable where significant inverter output and stored energy are required.

System Sizing Considerations

A 20kW three-phase installation should be designed around:

• Total simultaneous load
• Three-phase load distribution
• Motor and equipment starting requirements
• Required backup duration
