SolaX X3-HYBRID G4 – Three-Phase Solar Inverters for Energy Storage

The SolaX X3-HYBRID G4 is one of the manufacturer’s established three-phase hybrid inverter platforms.

Available power classes include:

5kW, 6kW, 8kW, 10kW, 12kW and 15kW.

The X3-HYBRID G4 combines solar PV conversion, high-voltage battery integration and intelligent power management for three-phase electrical installations.

SolaX X3-HYBRID G4 Technical Features

The manufacturer’s specification includes:

• Two independent MPPT trackers
• Support for up to 200% PV array oversizing
• Unbalanced three-phase output capability within model-specific limits
• High-voltage solar battery integration
• EPS backup power functionality
• On-grid and off-grid operating modes
• Supported parallel inverter arrangements
• Smart load control for compatible heat pumps and EV chargers
• Time-of-use energy management
• Integration with SolaXCloud monitoring

The X3-HYBRID G4 is relevant to buildings with three-phase electricity supplies, larger rooftop PV arrays and requirements for battery storage.

Three-Phase Unbalanced Output

One important feature is the ability to support unequal loads across the three AC phases within the inverter’s specified operating limits.

In real residential installations, household consumption is rarely distributed equally across all three phases.

Cooking equipment, heat pumps, air conditioning, EV chargers and other loads can create substantial phase differences.

An inverter with supported asymmetric output can improve flexibility in such installations, provided the electrical design, backup arrangement and local grid regulations permit the intended operating configuration.

SolaX X3-HYBRID G4 and Triple Power Battery Integration

The inverter supports selected SolaX Triple Power high-voltage battery systems.

Compatible battery families, module quantities and expansion arrangements depend on the inverter generation and the selected BMS.

For detailed technical information, read our SolaX Hybrid Inverter and Battery Compatibility Guide.

This guide explains the differences between X1-HYBRID G4, X3-HYBRID G4, X3-HYB-G4 PRO, X3-ULTRA and other SolaX platforms, including the correct battery configuration and expansion hardware.

SolaX X3-HYB-G4 PRO – Advanced 4–15kW Three-Phase Hybrid Inverters

The SolaX X3-HYB-G4 PRO introduces additional flexibility for professional installers designing residential and light-commercial energy storage systems.

The manufacturer’s range covers:

4kW, 5kW, 6kW, 8kW, 10kW, 12kW and 15kW.

Key Features of the SolaX X3-HYB-G4 PRO

• Up to three MPPT trackers, depending on model
• Up to 20A DC input current per MPPT
• Wide MPPT operating range of 110–950V

Why Dual Battery Ports Matter

The dual battery input architecture offers more flexibility than a conventional single-port hybrid inverter.

Instead of relying exclusively on one battery tower, supported configurations can use two independent battery connections.

This can be particularly useful when specifying larger high-voltage battery storage systems or planning future expansion.

However, the number of connected batteries, module voltage, allowable current and supported BMS configuration must all remain within the manufacturer’s compatibility requirements.

Features advertised as V2X-ready or subject to a future upgrade should not be treated as active functionality until the manufacturer confirms software, hardware and market availability.

Potential advantages include:

• Coordinated inverter and battery architecture
• Modular battery expansion
• Integrated communication between system components
• Reduced complexity in compatible system configurations
• Unified monitoring and energy management
• Residential backup functionality
• Smart load and time-of-use management

The correct configuration must still be selected according to household consumption, available photovoltaic generation, battery capacity and electrical connection requirements.

SolaX for Residential, Retrofit & Commercial Solar PV Projects

Residential Solar Energy Storage

SolaX hybrid inverters and compatible solar batteries can help homeowners increase photovoltaic self-consumption by storing surplus electricity for use outside solar generation hours.

For residential installations, equipment selection should reflect electricity consumption, solar array size, battery capacity and required backup functionality.

Solar Battery Retrofits

Existing photovoltaic installations can sometimes be upgraded with battery energy storage through a compatible AC-coupled or hybrid inverter architecture.

SolaX offers battery inverter and retrofit-oriented platforms, including selected FIT series products.

Before specifying a retrofit, installers should assess the existing inverter, metering system, grid connection approval and intended battery integration.

Backup Power & Off-Grid Applications

Selected SolaX hybrid inverters provide backup and off-grid operating modes.

However, an EPS-capable inverter is not automatically equivalent to a whole-building uninterruptible power supply.

Backup system design must address the required switching equipment, supported loads, starting currents, earthing arrangement, battery discharge capability and applicable electrical requirements.

Commercial Solar PV & Energy Storage

For commercial buildings, SolaX X3-ULTRA, X3-AELIO, AELIO ESS and TRENE provide different architectures for integrating solar PV generation with battery storage.

Commercial system design must consider both storage capacity in kWh and power conversion capacity in kW.

A large battery does not automatically provide sufficient discharge power for every commercial load.
