What’s inside the box?
OneStep.Solar sets consist of everything you need to generate energy.
Module
400W (1722 x 1134 x 30 mm),full-black with black backsheet
Higher energy production throughout the module's lifespan - enhanced durability thanks to non-destructive cutting
technology. This innovative approach minimizes the formation of micro-cracks and significantly reduces the risk of potential-induced degradation (PID).
High-efficiency modules with modern P type PERC+ multi-busbar cells.
Long module performance warranty - 84.8% of power after 25 years.
Renowned module manufacturer.
Individual optimization, separate MPPT charge controller for each module.
Maximum microinverter efficiency up to 96.7% thanks to new topology optimization.
Better thermal dissipation and highly waterproof microinverter due to the die casting and glue filling technology.
Microinverter
400W, black
User safety assured No risk of high DC voltage - maximum voltage of 60 V. Additional protection from double-layered rapid shutdown.
Built-in WiFi (2.4 GHz) and App for Remote Monitoring.
The world's first microinverter to meet the new EMC compliance standard.
Cable set
Each cable clicks into place with a satisfying snap – completely foolproof.
AC End Cable
Length: 5m, 10m, or 15m (customer's choice)
Equipped with a Schuko plug for plug-and-play connection to the power socket.
Module and microinverter are already factory-mounted on the bracket.
Pre-Assembled - just unfold and set up.
A design that seamlessly integrates with the surroundings - perfect for gardens and terraces.
Mounting accessories
Black bracket with adjustable angle for use on flat surfaces (only requires unfolding and ballast weighting).
Installation without the need for surface alteration, only requires stabilization with weights - offers flexibility in
space arrangement.
The wind deflector at the back of the structure reduces the required ballasting, facilitating placement on flat roofs.
Tilt angle of the module designed for better utilization of solar radiation.
