Specifications
Product Description
The Solax X1-Micro 1800W Single-Phase Solar Microinverter 4 MPPT IP67 is a high-power distributed AC solution for four photovoltaic modules. Each panel operates with its own MPPT, maximizing energy yield on roofs with shading or different orientations. The IP67 design, safety relay, and rapid shutdown ensure safe and reliable operation, while integrated Wi-Fi and SolaX Cloud simplify commissioning and maintenance with per-input telemetry.
Main Features
- Nominal AC power: 1800 VA; grid 1/N/PE 220/230/240 V (50/60 Hz).
- 4 independent MPPT (1 input per MPPT) to optimize each module.
- PV window: MPPT 22–60 V; Voc 60 V; start-up voltage 20 V.
- High current input: 4×16 A (max Isc 4×25 A).
- Max efficiency 96.5%; MPPT efficiency 99.5%; THDi <3%.
- Reactive power control: PF ~1 (0.8 lagging to 0.8 leading).
Advantages or Benefits
- Higher actual production: independent tracking minimizes losses due to shading and mismatch.
- Modular and scalable: add more microinverters per string as the system grows.
- Priority safety: low DC voltage on the roof, safety relay, and rapid shutdown.
- Outdoor reliability: IP67 and natural convection cooling without fans.
- Advanced management: SolaX Cloud with alarms, reports, and remote diagnostics.
Purpose or Applications
Perfect for homes and businesses with high-power panels (400–600 W), roofs with multiple orientations or fragmented spaces, repowering, and phased expansions where fine control per panel and maximum safety are required.
