SolaX X1-Hybrid-7.5-D 7.5kW Single Phase Hybrid Inverter for Residential PV and Battery Storage
The SolaX G4 X1-Hybrid-7.5-D Single Phase 7.5kW Hybrid Inverter is designed for modern residential solar PV systems where homeowners want more than simple solar generation. It combines PV inverter operation, battery charging, energy management and backup functionality in one professional hybrid inverter platform.
For solar installers, electricians, EPCs, solar wholesalers and solar distributors in Europe, the X1-Hybrid-7.5-D offers a strong technical match for high-performance residential energy storage projects. It is suitable for self-consumption systems, backup power applications, smart home energy management and complete solar battery kits.
According to the SolaX datasheet, the X1-Hybrid G4 range includes 3.0kW, 3.7kW, 5.0kW, 6.0kW and 7.5kW models, with the X1-HYBRID-7.5-D positioned as the highest output single phase model in this range.
7.5kW Output with Up to 15kWp Recommended PV Array Power
The SolaX X1-Hybrid-7.5-D is specified with 7,500W rated AC output power and 15.0kWp maximum recommended PV array power. This gives installers room to design residential PV systems with strong solar input capacity while using one compact single phase hybrid inverter.
The inverter supports 200% PV oversizing and up to 110% AC output, making it suitable for installations where the PV array is designed to improve generation across different seasons, roof orientations and daily production windows.
Dual MPPT Design for Flexible Solar PV Layouts
The X1-Hybrid-7.5-D includes 2 MPPT trackers with 1 string per MPPT, helping installers design more flexible solar PV systems. This is useful for residential roofs with different orientations, partial shading conditions or split array layouts.
The datasheet lists a maximum PV input voltage of 600V, rated PV input voltage of 360V, 70–550V operating voltage range, 70–550V MPPT voltage range, and 90V start-up voltage. Each MPPT supports 16A maximum input current and 20A maximum short-circuit current, making the inverter suitable for modern high-current solar panels.
Battery-Ready Hybrid Inverter for Energy Storage Systems
The SolaX X1-Hybrid-7.5-D is designed for solar battery integration, with a battery voltage range of 80–480V and 30A maximum charge/discharge current. The datasheet states compatibility with lithium and lead-acid batteries, giving installers flexibility when designing residential energy storage systems.
For professional PV installers and electricians, this makes the inverter a strong option for solar battery projects where the customer wants to increase self-consumption, store surplus solar energy and improve energy independence.
EPS Backup Output with Fast Switchover
The X1-Hybrid-7.5-D includes EPS off-grid output with battery, designed to support backup operation during grid interruptions when configured correctly. The datasheet lists 7,500VA rated EPS output power, 11,250VA peak EPS output power for 10 seconds, and <10ms switchover time.
This is important for installers designing backup-ready solar battery systems for homeowners who want essential load support, improved energy security and a more resilient residential PV system.
Smart Energy Management for Modern Solar Homes
The SolaX X1-Hybrid G4 platform includes smart management features such as smart load management, time-of-use energy management, CT compatibility with fast load response, global MPP scan for improved energy harvest and VPP-ready operation. These features help support residential solar projects where dynamic electricity tariffs, smart home loads, heat pumps, EV chargers and battery storage are part of the system design.
For installers, this allows the inverter to be positioned as part of a more complete energy storage solution rather than only a standard solar inverter.
IP65 Protection for Indoor and Outdoor Installation Flexibility
The SolaX X1-Hybrid-7.5-D has IP65 ingress protection, supporting installation flexibility for residential and light commercial environments. The datasheet also lists an operating temperature range from -35°C to +60°C, with derating above 45°C, and a maximum operating altitude of 3000m.
This makes it suitable for a wide range of European installation conditions, provided the inverter is installed according to SolaX requirements, local electrical regulations and project-specific environmental conditions.
