Voltacon Microinverter VMI 550W Grid Tied 230VAC Single MPPT - G98

0% of 100

With the maximum output power of 550W, VOLTACON VMI500 microinverter connects to 1 panel and enables module-level maintenance and management of the PV station by monitoring the power generation of each module. The micro-inverters provide 10-20% yield improvement in net harvested power (kWh/kW) compared to conventional string inverter-based solar systems. G98 Grid Standard Compliance. 10-Year Standard Warranty

Notice: This inverter requires a grid connection, it does not work off-grid or in parallel with off-grid inverters

The product is certified for the European and UK market, the list of certificates is available in the download tab. The inverter is also G98/G99 Compliant.

We offer an extended warranty 25 years, contact us for more details. The manufacturer's limited warranty is 10 years

Advanced Monitoring Down to Panel Level

This inverter requires the PLCC monitoring controller, it is installed outdoors, close to the micro inverters. An ethernet-based solution that creates a reliable connection between the microinverters and the online world. The software platform is available from your phone or the online browser and it does not require an annual subscription 

Maximum output power up to 550W/channel, adapted to 60,66,72,75 cell or 120,132,144,150sub cell PV panels
Static MPPT efficiency 99.80%
High reliability, IP67 (NEMA 6) enclosure, 6000 V surge protection

Voltacon modular micro-inverter-based solar systems have significant advantages vs. conventional DC string systems:

  • Maximised harvested energy: shading & defect immunity, reduced cabling losses, and power optimization (MPPT) for each module individually.
  • No single point of failure. Safer system as high voltage DC is eliminated: simple, standardized, cost-effective installation with no specialist DC installers. System management and performance are enhanced through communication down to the individual module level.
  • Voltacon inverters uniquely deliver high performance at low cost and high reliability, yielding ~20% cost of ownership advantage.

Advantage of de-centralized solar grid inverters

  • Enables True AC-Module.
  • 'Plug & Play' - lower installed cost.
  • Lifetime equivalent to solar panels – 25 years.
  • Higher harvested energy in ‘real world’.
  • High-performance system monitoring.
  • Rooftops compromised by shade.
  • Building Integrated PV (building walls and irregular surfaces).
  • PV on grid-connected power poles or streetlights poles.
Low DC voltage, and invisible.
