What the product is and who it suits

SolaX X3 Hybrid G4 5kW is a three-phase residential hybrid inverter designed for properties with a genuine three-phase electrical supply that want solar, battery storage and backup functionality in one platform. It is the smallest model in this X3 Hybrid G4 batch, which makes it the natural choice where the site needs three-phase hybrid logic more than it needs very high inverter output.

This is important because not every three-phase property is a high-demand commercial-style site. Some homes have three-phase service but still want a carefully sized hybrid system with storage, smart load support and backup-ready operation. The X3-HYBRID-5.0-D is built for that position in the market.

The wider X3 Hybrid G4 platform is also clearly designed as more than a basic PV inverter. SolaX highlights lithium-ion and lead-acid battery compatibility, on-grid and off-grid parallel operation, VPP readiness, smart loads management and intelligent time-of-use driven energy management. That places the product firmly in the hybrid storage category rather than in simple solar conversion only.

Key features and practical benefits

SolaX lists the X3-HYBRID-5.0-D with 5kW rated output power, up to 10kWp recommended PV array power, 2 MPPTs in a 1/1 string-per-tracker layout, a 180 to 950V MPPT voltage range and 16A maximum input current per MPPT. Those model-specific figures make it a good fit for smaller and medium three-phase residential arrays where two strings are enough and the system design does not require the higher PV allowance of the larger models.

The wider X3 Hybrid G4 platform also supports up to 200% PV oversizing, up to 110% AC output and up to 97.5% efficiency in charging and discharging. For hybrid systems, those are useful practical features because they improve how much value the installation can extract from both solar generation and stored energy across day-to-day operation.

• 5kW rated output power
• Up to 10kWp recommended PV array power
• 2 MPPTs with 1/1 string layout
• 180 to 950V MPPT range
• 16A maximum input current per MPPT
• Peak EPS output 12.0kVA for 10 seconds with less than 10ms switchover

Installation, protection and system flexibility

SolaX lists IP65 protection for the X3 Hybrid G4 family, along with dimensions of 503 x 503 x 199mm and net weight of 30 ±1kg for the 5kW model. That places the product in a robust wall-mounted three-phase class that still remains manageable for residential and light commercial installation.

The product page also highlights quick configuration via U-disk, smart load management for items such as heat pumps and smart EV chargers, global MPP scan and intelligent time-of-use energy management. On the platform level, SolaX also states on-grid and off-grid parallel function up to 150kW, which gives the family a clear scalability advantage over many smaller fixed-capacity hybrid products.

For standards and warranty, official SolaX documentation for X1/X3-Hybrid-G4 lists 5 years standard warranty from the earlier of installation or 9 months after production, with a free upgrade to 10 years standard warranty when the inverter is connected to SolaX Cloud and generation data is successfully uploaded. Official documentation also includes EN/IEC 62109 and G99 coverage for the family.

Why this variant may be the better fit

The 5kW model is the right fit where a site has a three-phase supply and wants hybrid storage functionality, but the actual inverter power requirement remains relatively modest. That can be the case on well-insulated homes, lower-demand properties or projects that value three-phase compatibility more than headline output.

It is also a sensible option where the buyer wants an accessible entry point into the X3 Hybrid G4 platform. Customers who later need more capacity can move up to the 8kW, 10kW or 15kW versions, while the 5kW model remains a clean and appropriately sized choice for more moderate three-phase systems.
