SolaX X1 Hybrid G4 5kW Single-Phase Hybrid Inverter

The SolaX X1 Hybrid G4 5kW Single-Phase Hybrid Inverter combines intelligent energy control with dependable build quality, delivering the flexibility installers need for medium-to-large domestic solar systems in the UK. It balances conversion efficiency, quiet operation and robust protection, ensuring reliable performance for years of service.

High-Efficiency Performance for UK Solar Systems

With dual MPPT inputs operating across a 70–550V range, the X1 Hybrid G4 5kW extracts maximum yield from every string. Its 97.6% peak efficiency and 99% MPPT response accuracy help maintain stable output even on shaded or multi-orientation roofs. The advanced DSP control platform continuously adapts to real-time irradiance, ensuring optimal energy harvest in Britain’s variable weather.

Built for Reliability & Protection

The rugged IP65 aluminium enclosure guards against rain and dust, while natural convection cooling keeps the unit below 30dB for near-silent operation. Integrated surge protection, insulation monitoring and residual-current detection protect both the inverter and connected circuits. Certified to EN 62109 and G99 standards, it’s fully approved for UK grid-connected systems and hybrid energy setups.

Key Features

• Dual MPPT tracking with 99% accuracy for multi-aspect arrays
• Peak efficiency 97.6% / Euro efficiency 97%
• IP65 fan-free design for quiet indoor or outdoor installation
• High-voltage LFP battery support with 30A charge/discharge
• Built-in communications (Wi-Fi, LAN, RS485, CAN, USB, optional 4G)
• Full G99 and EN 62109 compliance for UK use

If you’re wondering how efficient the X1 Hybrid G4 5kW remains during overcast days, its wide MPPT voltage window and rapid tracking algorithm allow the system to capture energy from low irradiance conditions typical across the UK.

Seamless Integration with Solar Panels & Battery Storage

The SolaX X1 Hybrid G4 5kW is purpose-built for integration with solar panels and battery storage systems. Supporting high-voltage LFP batteries with up to 30A charge/discharge, it provides rapid, efficient energy storage and retrieval. DC coupling minimises conversion losses, helping maximise return on investment for both new installations and retrofit hybrid upgrades. For installers, simple connection points and flexible communication options make commissioning fast and straightforward.

Smart Monitoring & Connectivity

The inverter connects seamlessly with SolaX Cloud for remote management and performance tracking. Homeowners and professionals can access live generation data, energy flow visualisation, and historical reports from any device. The X1 Hybrid G4 5kW includes built-in Wi-Fi and LAN connectivity, plus RS485, CAN, and USB interfaces as standard. Optional 4G communication modules are available for sites where wired connections are impractical.

Compact Design & Robust Construction

Despite its higher capacity, the inverter maintains a compact footprint, measuring roughly 460×510×185mm and weighing around 20kg. The IP65 housing provides reliable weatherproofing for outdoor installation, while passive cooling ensures quiet operation below 30dB. The durable aluminium body resists corrosion and maintains thermal stability for long-term reliability in British conditions.
