17.6kVA / 16kW Felicity IVGM16KLP3G 48V Three-Phase On/Off-Grid IP65 Hybrid Inverter

The 17.6kVA / 16kW Felicity IVGM16KLP3G Hybrid Inverter is specifically designed for high-capacity three-phase solar installations, combining 16kW rated power, a 48V battery architecture, on/off-grid capability and an IP65-rated enclosure.

Its most important differentiator is the three-phase configuration. Unlike the single-phase IVGM16KLP1G1, the IVGM16KLP3G is intended for properties and electrical systems where three-phase power distribution is required. This makes it particularly relevant to commercial premises, larger properties, workshops and other appropriately designed three-phase installations.

The 16kW output capacity provides substantial power for systems with multiple simultaneous loads, while the 48V battery architecture enables integration with appropriately sized battery storage.

Its on/off-grid capability further expands its application by allowing the inverter to form part of both grid-connected and battery-supported solar installations when correctly designed and configured.

Three-Phase Power Advantage

The defining feature of the IVGM16KLP3G is its three-phase configuration.

This makes it fundamentally different from a single-phase 16kW inverter, even though both may have the same total rated power.

A three-phase inverter is particularly relevant where the electrical installation distributes loads across three phases or where compatible three-phase equipment forms part of the load profile.

Potential applications include:

🏢 Commercial Buildings

🏭 Workshops

🏪 Business Premises

🏡 Large Three-Phase Homes

⚙️ Compatible Three-Phase Equipment

☀️ Commercial Solar Installations

The site’s existing phase arrangement and load distribution should be assessed before installation.

16kW High-Capacity Advantage

At 16kW rated power, this inverter is designed for substantially larger load requirements than conventional 5kW, 6kW or 8kW hybrid inverters.

Its higher capacity provides more room for multiple loads to operate simultaneously, subject to proper system sizing.

This makes it particularly useful where the solar installation is intended to provide a meaningful contribution to the property’s overall electricity demand rather than powering only a small essential-load circuit.

17.6kVA / 16kW Power Rating

The IVGM16KLP3G is specified at:

17.6kVA apparent power

16kW rated active power

These specifications describe different electrical quantities. The 16kW rating is particularly important when assessing the real-power requirements of connected loads, while kVA represents apparent power.

Both figures should therefore be retained in the product specification rather than reducing the product description to only one rating.

On/Off-Grid Advantage

The IVGM16KLP3G supports on/off-grid operation, giving it flexibility for more advanced solar installations.

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

🔋 Off-Grid / Battery-Supported Operation
Allows compatible battery storage and solar generation to support loads according to the inverter’s supported configuration.

This makes the inverter particularly relevant where the customer wants to combine solar generation, battery storage and utility power rather than relying on only one energy source.

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

48V Battery Architecture

Despite its substantial 16kW output, the IVGM16KLP3G operates on a 48V battery architecture.

At this power level, battery selection is critical.

The battery bank must be assessed for:

• Correct 48V-class operating range
• Sufficient continuous discharge capability
• Required energy capacity in kWh
• Charging capability
• Required backup duration
• Battery-to-inverter communication where applicable
• Suitable high-current DC cabling
• Correct battery-side protection

Simply connecting a battery because it is labelled 48V is not sufficient for a 16kW system.

IP65 Protection Advantage

The IP65-rated enclosure provides a defined level of protection against environmental exposure.

The rating indicates:

6 – Dust-tight under the relevant test conditions.

5 – Protection against water jets under the relevant test conditions.

This makes the inverter better suited to appropriately selected installation environments where dust and moisture exposure are considerations.

IP65 does not mean the inverter can be submerged or installed without regard to ventilation, temperature, direct weather exposure or Felicity’s installation requirements.

Three-Phase vs Single-Phase 16kW Felicity

The IVGM16KLP3G should not be confused with the IVGM16KLP1G1.

The key reason to select the IVGM16KLP3G is therefore not simply higher power—it is specifically intended for a three-phase electrical architecture.

Commercial Solar Advantage

The combination of 16kW + three phase + hybrid operation gives this model a particularly strong commercial application.

Potential uses include appropriately sized:

🏢 Office Buildings

🏪 Retail Premises

🏭 Workshops

💻 Business IT Systems

💡 Commercial Lighting

🧊 Compatible Refrigeration

⚙️ Selected Three-Phase Loads

🔌 Essential Commercial Circuits

The actual system should be designed from a site load assessment, including how loads are distributed across the three phases.

Large Three-Phase Home Advantage

Some larger residential properties use three-phase electrical supplies because of their total electrical demand or the types of equipment installed.

For such properties, the IVGM16KLP3G offers a high-capacity hybrid platform that can be integrated into an appropriately engineered three-phase solar and battery system.

This is particularly relevant where the objective is to support multiple household circuits across a larger electrical installation rather than providing basic emergency backup.

Solar + Battery + Grid Integration

A properly designed system can broadly operate as:

☀️ Solar PV → ⚡ Felicity IVGM16KLP3G ↔ 🔋 48V Battery Storage

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

This architecture allows solar, battery storage and grid supply to work within one integrated energy system according to the inverter’s supported operating modes.

The exact PV voltage range, maximum PV input power, MPPT configuration and charging specifications were not supplied and should be confirmed before designing the solar array.

Battery Storage for a 16kW System

A high-capacity inverter requires careful battery sizing.

For example:

Inverter kW = Power capability

Battery kWh = Stored energy

A 15kWh-class battery does not turn the inverter into a 15kW inverter, and a 16kW inverter does not automatically require exactly 16kWh of storage.

Battery capacity should instead be calculated from the required loads and desired backup duration.

The battery system must also be capable of delivering the required DC power without exceeding its permitted discharge limits.

Applications / Use Cases

🏢 Commercial Solar Systems – suitable for properties operating on compatible three-phase distribution.

🏭 Workshops – high-capacity hybrid platform for appropriately calculated workshop loads.

🏡 Large Three-Phase Homes – suitable for substantial residential solar and battery systems.

☀️ On/Off-Grid Solar – integrates solar, battery storage and utility supply in appropriately configured systems.

🔋 High-Capacity Backup – suitable where substantial battery-backed power is required.

🏪 Business Premises – useful for appropriately sized lighting, IT, refrigeration and other commercial loads.

System Sizing Considerations

For a 16kW three-phase installation, assess:
