SolaX X1-VAST Single-Phase Hybrid Inverter (AU/NZ) – 5kW / 6kW / 8kW / 10kW

The SolaX X1-VAST is a high-performance single-phase residential hybrid inverter designed for modern solar + battery systems. With high PV capacity, fast backup switchover, and flexible battery expansion, it’s a strong option for homes wanting greater energy independence and resilience.

Highlights

• Hybrid-ready: Supports high-voltage lithium batteries with dual battery ports and flexible expansion options.
• High PV capability: Supports up to 200% PV oversizing and up to 20A DC input per MPPT (model dependent).
• Fast backup (EPS): UPS-level switchover < 10 ms, with up to 200% EPS output for 10 seconds (with battery connected).
• Safety built-in: Type II SPD on both DC and AC sides; optional AFCI (where supported).
• Outdoor-ready: IP66 enclosure and wide operating temperature range.

Available Models

Note: PV sizing and MPPT configuration vary by model. Always confirm final design with your installer and local grid requirements.

Key Electrical Specifications (AU/NZ Datasheet)
