What the SolaX X3 Hybrid G4 6.0kW is

SolaX X3 Hybrid G4 6.0kW Three Phase Hybrid Inverter is a three-phase residential hybrid inverter in the X3 Hybrid G4 family. The exact model in this row is X3-HYBRID-6.0-D, and that matters because the source material supplied for the batch mixed this SKU with the wrong power level in places. The SKU itself identifies the exact variant correctly as the 6.0kW model, and the current official SolaX product page and datasheet both confirm that X3-HYBRID-6.0-D sits within the 5.0kW to 15.0kW X3 Hybrid G4 range.

This is therefore a hybrid inverter for buyers who want PV, battery and backup capability in one three-phase unit. It is not merely a battery-ready string inverter. The battery range, EPS rating, switchover performance and hybrid control features are all central to how the product is intended to be used.

Who it suits

The 6.0kW X3 Hybrid G4 suits three-phase homes, larger domestic properties, outbuildings and smaller mixed-use projects where solar generation, battery storage and backup support are all part of the brief. It is especially useful for households that want to increase self-consumption, improve resilience during outages and prepare for a more integrated home energy setup including batteries and EV charging.

Because the model supports up to 12kWp maximum recommended PV array power, it can also suit homes where the DC side is relatively ambitious compared with the nominal inverter output. That matters on roofs where the buyer wants to extract more generation over the course of the day rather than sizing the DC field conservatively.

Key features and practical benefits

• 6kW rated three-phase hybrid output.
• Up to 12kWp maximum recommended PV array power.
• 200% PV oversizing and up to 110% AC output at family level.
• Two MPPT trackers in a 1 / 1 arrangement for the 6.0kW model.
• 120V to 800V battery range.
• 30A maximum charge and discharge current.
• 6kVA rated EPS output and 12.0kVA peak EPS output for 10 seconds.
• Switchover time under 10ms.
• Lithium and lead-acid battery compatibility.
• On-grid and off-grid parallel function up to 150kW at family level.
• Type II SPD on AC and DC sides and optional AFCI.
• IP65 enclosure.

The main benefit is hybrid functionality at a realistic residential scale. Many homes do not need a 10kW or 15kW hybrid inverter, but they still want storage integration, backup support and smarter energy control. The 6.0kW model gives those features in a more proportionate format.

The second benefit is system resilience. A switchover time under 10ms and peak EPS output of 12.0kVA for 10 seconds make the inverter far more useful during outages than a simple grid-tied product that shuts down when the grid goes away. That can be valuable for homes with essential circuits or more energy-aware occupants.

Technical details that matter in practice

The official X3 Hybrid G4 datasheet lists X3-HYBRID-6.0-D at 12kWp maximum recommended PV array power, 1000V maximum PV input voltage, 640V rated PV input voltage, 180V to 950V MPPT voltage range and 200V start-up voltage. For the 6.0kW model, the datasheet confirms two MPPT trackers in a 1 / 1 string arrangement, 16A / 16A maximum input current per MPPT and 20A / 20A maximum short-circuit current per MPPT.

On the AC side, the model is listed at 6kW rated output power, 8.7A rated output current, 6.6kVA maximum output apparent power and 9.7A maximum output continuous current. Maximum AC input apparent power is 12kVA and maximum AC input current is 19.3A. Rated AC voltage is shown as 3 / N / PE, 220 / 380V or 230 / 400V and rated frequency is 50Hz / 60Hz.

The battery and backup specification is especially important. Battery type is listed as lithium / lead-acid, battery voltage range is 120V to 800V, maximum charge / discharge current is 30A, rated EPS output power is 6kVA, peak EPS output power is 12.0kVA for 10 seconds and switchover time is listed at less than 10ms. Maximum efficiency is 98.0% and European efficiency is 97.7%.

The enclosure is IP65 rated, dimensions are 503 x 503 x 199mm and net weight is 30 ± 1kg. Cooling for the 6.0kW model is listed as natural cooling, which is useful in domestic environments where lower noise and reduced maintenance are valued.

Installation and fitment considerations

The X3 Hybrid G4 6.0kW should be chosen where the site genuinely wants hybrid operation, battery compatibility and EPS support rather than only grid-tied PV generation. The model is especially useful where the project is three-phase and the household wants a more integrated energy system that can support storage and controlled backup.

The two-MPPT layout is helpful on homes with split roof faces or more varied PV placement. Natural cooling makes the inverter easier to place near domestic spaces than a louder fan-cooled unit, while the compact 503 x 503 x 199mm housing helps it fit into utility areas, garages and similar wall-mounted locations.

Because the model supports both lithium and lead-acid batteries, the battery side should still be designed carefully around the exact storage product being used. The inverter’s hybrid value comes from the whole system design, not just the inverter body on its own.

Why this exact variant may be the right choice

The X3 Hybrid G4 6.0kW is the right choice when a three-phase project wants a moderate-output hybrid inverter with verified battery and EPS capability. Compared with larger X3 Hybrid G4 models, it gives a more proportionate answer for homes and smaller sites that still want storage integration. Compared with a simple string inverter, it adds battery charging, backup support and deeper energy-management potential.

It is also the correct answer for this exact SKU. Where source copy has confused the power level, the verified X3-HYBRID-6.0-D model remains clearly defined as the 6.0kW variant and should be treated as such for specification and customer-facing content.
