Description
xWith a maximum output power of 550W, VOLTACON VMI550 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 up to 20% yield improvement in net harvested power (kWh/kW) compared to conventional string inverter-based solar systems.
Module-level data can be uploaded to the monitoring platform via VOLTACON data transfer units through PLCC/Zigbee. G98 Grid Standard Compliance. 10-Year Standard Warranty
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 of 25 years, contact us for more details. The manufacturer's limited warranty is 10 years.
Notice: This inverter requires a grid connection, it does not work off-grid or in parallel with off-grid inverters
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
Features
- 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. A 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 the ‘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 streetlight poles.
SAFETY
- Low DC voltage, and invisible.
QUALITY
- Components selected from world-class brands.
OPTIMIZATION
- Individual MPPT for each module.
PARALLEL INPUT
- 18A continuous input.
FLEXIBILITY
- Adapts to any system size and optimizes space.
PLUG & PLAY
- Hand-in-hand design. Fewer add-ons.
25 YEARS
- Long 25 years lifetime. Up to 15 years warranty.
SMART
- Module-level online smart monitoring.
