Inverters and converters
The solar inverter is the central component of a photovoltaic system: it converts the direct current (DC) produced by the panels into alternating current (AC) that can be used at 230V (and, depending on the installation, fed into the grid). In this category, you will find solutions suitable forself-consumption, battery storage and off-grid projects: inverters, converters, micro-inverters and accessories.
To make the right choice, identify your needs:
Production and injection/consumption
Grid-connected inverterBattery management + self-consumption
Hybrid inverterPanel-by-panel optimisation
Micro-inverterDC/AC conversion in stand-alone mode
230V converterAlso check the power (W/kVA), single-phase or three-phase, and battery compatibility (e.g. 12V/24V/48V).
Choose in 30 seconds
- Grid: for self-consumption/feed-in with solar panels.
- Hybrid: if you plan to use a battery (storage, optimisation, possibly backup).
- Micro-inverter: ideal if there is shade, multiple orientations, optimisation per panel.
- Converter: to convert DC to AC according to your needs (mobile/remote site/specific installations).

The revolution of N-Type ABC and TOPCon cells
The photovoltaic market is undergoing a profound transformation with the progressive shift from P-Type cells to N-Type architectures. At Wattuneed, we integrate the latest innovations such as TOPCon (Tunnel Oxide Passivated Contact) and ABC (All Back Contact) to offer our customers energy productivity that exceeds conventional standards.
TOPCon N-Type: The new standard for high efficiency
TOPCon technology is establishing itself as the natural successor to PERC. By adding an ultra-thin oxide layer, it drastically reduces electron recombination losses. The result: a cell efficiency exceeding 25% and, above all, an improved temperature coefficient. This means your panels lose less power during hot days, a crucial advantage for rooftop installations where ventilation is limited.
ABC (All Back Contact): Aesthetics at the service of performance
ABC technology represents the pinnacle of current solar engineering. Unlike classic panels, all electrical contacts are placed at the rear of the cell.
- Zero shading: The front side is 100% dedicated to photon capture, increasing the active surface area.
- Premium Full Black Design: Without visible metal grids (busbars), the panel offers a deep and uniform black, ideal for demanding architectural projects.
- Increased durability: The ABC structure is inherently more resistant to micro-cracks caused by temperature variations.
Bifaciality and yield in low light conditions
The use of N-Type substrates allows for a much better spectral response. Our panels capture light more effectively at dawn, dusk, or in overcast weather. Coupled with a bifacial structure, this technology allows for the recovery of albedo (ground reflection), increasing energy gain by up to 20% depending on the type of surface (white gravel, light membranes, or ground mounting).
By choosing these technologies at Wattuneed, you are investing in equipment with low degradation (less than 0.4% per year), ensuring maximum profitability for over 30 years.
