The SolaX X1‑HYBRID‑7.5‑D G4 7.5 kW Hybrid Inverter is a high-performance 7.5 kW single phase hybrid solar inverter from SolaX Power, engineered to optimise residential solar systems with battery storage support. Part of the X1-Hybrid G4 series, this inverter combines efficient PV conversion, flexible energy management features, and robust backup capabilities to help homeowners maximise solar self-consumption, reduce grid reliance, and maintain power during outages.

At its core, the X1-Hybrid G4 operates as a hybrid inverter, meaning it manages both solar PV input and battery charge/discharge within a single unit. It supports dual MPPT (Maximum Power Point Tracking) channels that allow two separate PV string inputs to track their peak power points independently — improving energy harvest even when panel orientations or shading vary. With 200 % PV oversizing and support for up to 110 % AC overload, the inverter ensures maximum utilisation of your solar array under diverse sunlight conditions.

Efficiency and power performance are among the standout strengths of this model. It typically delivers up to ~97 % charging and discharging efficiency, ensuring that most of the solar energy captured is effectively converted into usable power or stored energy. The advanced inverter also offers low startup voltage, enabling it to begin operating earlier in the morning or under lower light conditions when many other inverters would remain idle.

Safety and durability are built into the design with an IP65 weatherproof rating, making it suitable for both indoor and outdoor installations exposed to dust or moisture. Integrated Surge Protection Devices (SPD) add an extra layer of protection to both AC and DC sides, safeguarding the inverter from transient overvoltages. Fast switchover times (under ~10 ms) between grid and backup modes help maintain power continuity during outages, while the inverter’s EPS output capability can deliver significant surge output (up to ~150 % for short bursts) to help start heavier appliances.

The Solax X1-Hybrid G4 also supports multiple operating modes, enabling homeowners to tailor energy management strategies such as time-of-use optimisation, self-consumption prioritisation, or backup readiness. It is compatible with both lithium-ion and lead-acid battery types, and can even work in parallel with additional units for systems up to ~15 kW, providing scalability for growing energy needs. Smart load management and VPP-ready capabilities offer advanced features rarely found in hybrid inverters at this price point.
