SolaX X1-IES 6.0kW Single Phase Hybrid Inverter

SolaX X1-IES 6.0kW: The Intelligent Hybrid Inverter for Energy-Smart Homes

The SolaX X1-IES 6.0kW inverter is built for modern British households seeking solar independence, battery backup, and full control over energy use. With three MPPT trackers, high-voltage battery compatibility, and seamless emergency power switching, it’s one of the most advanced single-phase hybrids available. Whether you’re installing for self-consumption, backup resilience or future grid integration, this unit delivers flexibility and efficiency in a compact format.

Unmatched Solar Flexibility with 200% Oversizing

Designed to extract the maximum from your solar array, the X1-IES 6.0kW supports PV inputs up to 12kW , double its rated output. This means you can generate more during low-light days and still export or store efficiently. Its 3 MPPTs allow you to split your array orientation and shading to maximise performance across roof spaces.

• 200% PV oversizing (up to 12,000W DC)
• 3 MPPTs for complex roof configurations
• Smart export control and remote adjustment

Hybrid Inverter with High Voltage Battery Integration

The X1-IES series is fully compatible with SolaX’s Triple Power high-voltage batteries, allowing scalable storage up to 20.4kWh. It also supports third-party battery options with CAN or RS485 protocols, making it a versatile hub for any residential solar-plus-storage setup.

• Compatible with SolaX HV batteries (5.8kWh–20.4kWh)
• Supports CAN/RS485 for wider battery options
• Max 30A charge/discharge current

EPS Backup Power with UPS-Class Switching

During grid failures, the X1-IES switches to EPS (emergency power supply) mode in under 10 milliseconds, fast enough to keep sensitive electronics running. It even allows up to 200% EPS output for 10 seconds, supporting power-hungry devices during switchover events.

• <10ms switchover time
• 200% EPS output for 10s peak loads
• Supports off-grid and micro-grid operation

Engineered for Long-Term Reliability and Safety

With an IP66-rated enclosure, the X1-IES can be installed outdoors or indoors with complete confidence. It meets all required UK grid compliance certifications, supports 24/7 remote monitoring through SolaX Cloud, and comes with a 10-year manufacturer warranty as standard.

• IP66 waterproof and dustproof design
• G99 certified and EN 50549-1 compliant
• 10-year standard warranty
