Description
xVoltacon VMI600 600W Solar Microinverter with Wi-Fi – G98 Compliant
The Voltacon VMI600 is a 600W grid-tied solar microinverter with integrated Wi-Fi monitoring. Designed for single panel installations, it delivers individual maximum power point tracking at module level, improving energy yield in systems affected by partial shading or mixed orientations. G98 compliant and ENA registered (ZHEJI/15702/V1/A1), it is suitable for UK residential and commercial grid-connected solar installations.

- G98 compliant for UK grid connection
- ENA registered: ZHEJI/15702/V1/A1
- 10-year standard warranty; 25-year optional extended warranty available
Product Overview
Unlike string inverters, which track the power output of an entire array collectively, the VMI600 tracks each panel individually. This means that shading, soiling, or degradation on one panel does not reduce the output of the entire string, improving overall system yield in real-world conditions.
The integrated Wi-Fi allows each inverter to be monitored independently without a separate data gateway or communications hub. Each unit reports generation data and status information directly, enabling module-level fault detection and performance analysis.
The VMI600 uses GaN MOSFET technology and has no electrolytic capacitors or cooling fans, reducing the number of wear components and supporting a long service life. The high-frequency transformer design provides electrical isolation between the PV input and the AC output.
Applications
- Residential rooftop solar installations with partial shading
- Rooftops with multiple orientations or complex layouts
- Building-integrated PV on walls or irregular surfaces
- Commercial installations requiring module-level monitoring
Installation and Safety Notes
This inverter must be installed by a qualified electrician or MCS-accredited solar installer. G98 notification to the DNO is required before connection. AC wiring, circuit protection, and earthing must comply with IET Wiring Regulations. This inverter requires a live grid connection to operate and will not function off-grid or in parallel with off-grid inverters.
