The offer applies to the 5.0 kW, 6.0 kW and 12.0 kW models, making these already versatile hybrid inverters even more attractive for installers, EPC companies and professional buyers planning solar PV and energy storage projects.
The SolaX X3-Hybrid G4 is designed for much more than standard grid-connected solar generation. It supports battery integration, EPS backup operation, intelligent load management and flexible system expansion, making it suitable for modern residential and small commercial energy systems.
Three Popular Power Classes, One Strong Promotion
The promotion includes three of the most popular X3-Hybrid G4 sizes:
SolaX X3-Hybrid G4 5.0 kW + FREE MATEBOX Basic
SolaX X3-Hybrid G4 6.0 kW + FREE MATEBOX Basic
SolaX X3-Hybrid G4 12.0 kW + FREE MATEBOX Basic
The 5.0 and 6.0 kW versions are well suited to typical three-phase residential installations, while the 12.0 kW model provides significantly more capacity for larger homes, higher electricity consumption and selected light-commercial applications.
According to the SolaX datasheet, the X3-Hybrid G4 battery input operates across a 180–800 V battery voltage range and supports lithium-ion as well as lead-acid batteries, with up to 30 A continuous charge and discharge current.
Up to 200% PV Oversizing
One of the strongest features of the X3-Hybrid G4 platform is its ability to work with a significantly oversized PV array.
SolaX specifies up to 200% PV array oversizing and up to 110% AC overload output for the series.
This gives installers more flexibility when designing systems for morning and afternoon production, lower irradiation periods or projects where the solar panels are distributed across multiple roof orientations.
The maximum PV array power differs by model. The 5.0 kW version supports up to 10,000 Wp, the 6.0 kW version up to 12,000 Wp, while the 12.0 kW model supports up to 24,000 Wp of PV array capacity.
That makes the 12 kW version particularly interesting for larger solar PV systems where the customer wants to combine strong daytime production with battery storage and future electrification.
Fast EPS Backup with Less Than 10 ms Switchover
The X3-Hybrid G4 is not simply a solar inverter. With a compatible battery system, it also supports EPS backup operation.
SolaX specifies a switchover time of less than 10 ms, allowing selected loads to continue operating during a grid outage when the system is configured correctly.
The inverter also supports short-duration peak EPS power. For example, the 12.0 kW model can deliver up to 22.5 kVA for 10 seconds in backup operation.
This is particularly useful for loads with higher starting currents, such as pumps, motors and other equipment that may briefly require more power than their normal running consumption.
Three-Phase Unbalanced Output
Real homes and commercial buildings rarely load all three phases equally.
The X3-Hybrid G4 supports three-phase unbalanced output, with SolaX specifying up to 5 kW output on a single phase.
For installers, this can make the system much more practical in real-world applications where kitchen appliances, heat pumps, office equipment or other loads are unevenly distributed across the electrical system.
Parallel Operation up to 150 kW
The X3-Hybrid G4 platform also supports on-grid and off-grid parallel operation.
According to the manufacturer, systems can be expanded in parallel up to 150 kW total power.
That significantly broadens the use case beyond a standard residential solar installation and allows the platform to be considered for larger properties and more demanding projects where multiple inverters are required.
Intelligent Energy Management and VPP-Ready Architecture
The inverter provides five operating modes and two configurable charging periods. SolaX also highlights intelligent load management, including applications such as heat pumps, as well as CT and meter compatibility.
The X3-Hybrid G4 is also described as VPP-ready, supporting future applications where battery storage, flexible consumption and external energy management become increasingly important.
This matters as European electricity markets move towards dynamic tariffs, smarter grids and greater use of distributed energy storage.
For the installer, that means the inverter can form the core of a system that does more than simply convert DC solar power into AC electricity.
High Efficiency and Modern PV Compatibility
The series reaches a maximum efficiency of 98.0% and a European efficiency of 97.7%. SolaX also specifies up to 98.5% PV-to-battery efficiency and up to 97.5% battery-to-AC efficiency.
The DC inputs support modern higher-current solar panels. The datasheet lists up to 16 A per single string input, while larger models use higher-current MPPT configurations where applicable.
For procurement and system design, the exact solar panel model should still be checked against inverter voltage, current and short-circuit current limits before installation.
IP65 Protection and Integrated SPD
The SolaX X3-Hybrid G4 carries an IP65 protection rating and includes integrated surge protection.
The operating temperature range is specified from -35°C to +60°C, with derating above +45°C.
This gives installers flexibility across a wide range of residential and commercial environments, although installation conditions, ventilation and local electrical requirements must always be taken into account.
Why the FREE MATEBOX Basic Promotion Matters
The current offer is more than a simple inverter discount.
By including a MATEBOX Basic at no additional cost with the selected 5.0, 6.0 and 12.0 kW X3-Hybrid G4 models, the promotion improves the overall value of a complete SolaX hybrid system and makes procurement easier for installers who already work with SolaX energy storage solutions.
For professional buyers, this can help simplify project costing and make complete system proposals more competitive.
The promotion is especially relevant for installers looking to build systems that combine solar panels, a hybrid solar inverter, solar battery storage and backup capability in one coordinated platform.
A Strong Opportunity for Installers and Resellers
The SolaX X3-Hybrid G4 already provides a strong technical platform: high PV oversizing, fast backup switching, battery integration, intelligent load management, three-phase unbalanced output and scalable parallel operation.
Adding a free MATEBOX Basic makes the 5.0, 6.0 and 12.0 kW versions particularly attractive for new projects.
For B2B buyers, the key is to select the correct inverter size, confirm the compatible solar battery configuration and verify the exact accessories required for the final system.
