When we draw up a quotation, we assess the needs and capacity required for the customer's project. To do this, we request a photo file of the site to determine technical aspects such as single-phase/three-phase electrical connection, roof type, household consumption, and so on.

Once the file has been completed with the necessary information, our team examines the feasibility of the project based on the offer submitted. Once the file has been finalized and approved, we contact you to schedule the installation of the system. Wattuneed provides an equipment warranty and installation follow-up, and the installer provides a ten-year warranty. During the validation stages, adjustments may be made to the budget and equipment, depending on the criteria mentioned above.

The rates are valid for full-floor or R+1 (1st floor) installations that do not require mechanical lifting equipment.
Access to the home must be easy, without complexity, and on an unprotected site.
Travel costs are free for the first 50 km. Beyond that, each kilometer will be billed at €1 when the file is validated
For all requests, please contact us for a personalized offer.

Solar panels

Sofar Solar 8 kVA three-phase hybrid inverter - HYD-KTL-3PH

The HYD 5K...20KTL-3PH is a versatile three-phase hybrid inverter for solar and storage applications. During grid failures, it can provide up to 20 kW of unbalanced three-phase emergency power supply (EPS) in 10 ms thanks to its integrated EPS port.

Two MPPTs and two independent battery ports (on models 10K to 20KTL) enable multiple battery capacity configurations in 2.5 kWh steps.

Up to 10 inverters can be connected in parallel on the EPS and AC port, making this device ideal for microgrid installations (on or off-grid).

The integrated energy management system features several user-friendly modes, optimizing the user experience, including an automatic self-use mode. Users can also define different time and/or date ranges, or rules for the day of the week.

All modes can be easily configured on the large LCD display. In particular, this inverter is compatible with SofarSolar's AMASS Store high-voltage battery unit (GTX 3000-H). A WiFi stick is supplied with the inverter, for easy connection to the Sofar monitoring portal.

And it's user-friendly, with simplified start/stop functions.

Expansion flexibility: The system offers a modular, stackable design for easy expansion of battery capacity, adapted to the changing energy needs of residential users.

Seamless integration: Compatible with the HYD 5K-20KTL battery inverter series, the system ensures seamless integration into existing installations, simplifying the use and expansion of the energy storage system.

Efficiency and ease of use: The BDU + Base distribution unit guarantees optimum battery utilization thanks to efficient management of the battery pack balance. The modular design, combined with simplified start/stop functions, provides a user-friendly experience for residential users while ensuring low energy consumption.

Investment incentives for self-consumption

The self-consumption bonus, conditional on photovoltaic self-consumption and sale of the surplus, is compulsory for designated buyers, with tariffs revised quarterly. Opt for over-mounted solar panels on your roof, requiring the intervention of a certified professional and a power limited to 100 kWp. Ground-mounted panels are not eligible.

How much is the premium for self-consumption?

The premium for photovoltaic self-consumption depends on the size of your installation and varies every quarter. It is determined by four categories based on peak power:

When and how should surplus sales be invoiced?

The process for invoicing surplus electricity is quick and simple: once a year, on the anniversary of the contract start date, take a meter reading.
