2.7 kWp solar kit for self-consumption with storage: generate and consume your electricity on site. With the WKS EVO Circle Pro hybrid inverter, the installation operates in self-consumption mode without feeding into the grid: a real advantage in terms of simplifying procedures (no resale of surplus energy, therefore no Consuel certification required for feeding into the grid).
Key advantages: N-Type bifacial panels for excellent efficiency, including via reflected light. The 5.12 kWh LiFePO4 battery stores the energy produced during the day for use when production drops in the evening and at night, increasing your self-consumption rate.
Production & savings (central France): 450 Wp panel. Maximum expected annual production: 2,970 kWh/year (indicative). Potential savings: £891/year, estimate based on £0.30/kWh. Our advisers carry out a personalised study based on your site and your usage.
Why choose this kit? High efficiency, robust storage (IP65 + heating), protections included, scalable solution.
Customisation: addition of panels, adaptation of cable lengths, choice of other batteries/capacities according to your needs.

Transform solar energy into electrical autonomy with this solar kit, perfectly designed for individual self-consumption.
This solar kit offers tailor-made options to perfectly meet your energy needs.
Whether you are looking to power an independent site or gradually reduce your dependence on the grid, this hybrid kit with lithium battery will help you achieve greater autonomy and savings.
The basic kit includes 6 solar panels, a WKS Evo Circle Pro 6.5 kVA 48V hybrid inverter, a Leapton EL-A05 5.12kWh 100Ah LiFePO4 lithium battery, solar cables to connect the panels to the inverter, and an optional panel mounting system. (The mounting system, cabling and protection can be modified to suit your needs).
All our kits are configurable. In the options, you can click on the product to choose another model or change the quantities to adapt the kit to your needs.You can also see the details of the selected products directly below the price.
Important notice for our customers in Belgium:An environmental contribution of €124.27 excluding VAT will be applied to the purchase of each Leapton EL-A05 lithium battery.
More information at the bottom of the page.
Optimised solar production and autonomy
The kit is designed with 6 panels and a power output of 6.5 kVA, offering solar production suitable for an average household, enhanced autonomy thanks to the lithium battery, durable installation on an aluminium ground structure, and effectively reducing your electricity bill while gaining energy independence.
Production + storage for continuous use
The panels produce energy when the sun is shining, and the battery (or batteries) provides energy at night or during periods without sunshine.
Flexibility and scalability
If your needs change (increased consumption), it is possible to increase the capacity of the system (more panels or batteries), as long as the size allows it.
Safety & reliability
Surge protection, circuit breakers, disconnectors, warranties — to ensure that the installation operates continuously without any problems.
Profitability & peace of mind
You invest in sustainable energy independence, reduce or even eliminate your electricity bill (or your dependence on it), and add value to your "off-grid" home.
Chosen from among the latest technologies, this panel offers unrivalled efficiency.
See the product sheet in our panels section for more information.
And don't forget, we offer you the flexibility to choose the panel model according to your preference.
We invite you to consult our solar production simulator to determine precisely what your solar production will be.

Durability
The WKS Evo Circle PRO 6.5 kVA / 48 V inverter is the ideal technical solution for an autonomous or hybrid solar system.
It combines power and intelligent energy management. It ensures a stable power supply thanks to its fast-switching UPS (backup) function (10 to 20 ms, depending on the mode).
A key technical feature is its programmable dual AC output.
Equipped with a 120 A MPPT regulator, it optimises massive photovoltaic production (up to 9,000 Wp). It is designed for 48V batteries, with validated compatibility for lithium batteries (LiFePO₄).
Its all-in-one design (inverter + charger + regulator) simplifies installation. Wi-Fi connectivity and a dedicated mobile app (iSolar / WatchPower) enable remote control.
For larger projects, it is scalable up to 6 units in parallel (single-phase or three-phase) for a total power of 39 kW.
Key technical specifications:
Choose the battery that suits your needs:
• Pylontech US5000: the "market standard/ESS ecosystem" choice
The US5000 is a widely used model in residential applications (rack/ESS format), with modularity of up to 16 units and CAN/RS485 communications for UPS integration. The page highlights its reliability, modularity and service life of up to 6,000 cycles at 80% DOD.
• Leapton EL-A05: the choice for "harsh conditions/outdoor use"
Its key differentiators are its IP65 rating and heating function, which allows it to remain operational (discharge) down to -20°C, which is very useful if the battery is installed in an unheated room, garage, technical shelter or outdoors. It also boasts a power rating of 1C (100 A) ≈ 5.12 kW, which is useful for power demands.
Permanent or secondary residence
This kit provides enough energy to power lighting, sockets, small appliances, a water pump and light heating, while storing electricity in the lithium battery for use even at night or on cloudy days.
Leisure/holiday accommodation
Ideal for a tiny house, cottage or isolated dwelling, allowing you to enjoy electrical comforts without depending on the grid.
Self-contained extension/garden shed
Perfect for a workshop, studio or independent office, the kit powers essential needs without running cables from the house.
Hybrid/backup use
If the accommodation is connected to the grid, the battery maximises self-consumption and provides backup power during outages or consumption peaks.
Optimisation of autonomy and comfort
With its six 450 Wp panels and lithium battery, this kit maximises self-consumption, allows flexible use of electricity throughout the day and guarantees sustainable energy comfort, even during consumption peaks or periods without sunshine.
As part of our commitment to regulatory compliance and environmental responsibility in Belgium, we would like to inform our customers that the purchase of a Leapton EL-A05 5.12kWh 100Ah LiFePO4 lithium battery is subject to a mandatory environmental levy.
An amount of €124.27excluding VAT must be added to each battery purchased as a direct contribution to Bebat, the organisation responsible for managing batteries and accumulators in Belgium. This measure complies with current Belgian environmental legislation.
When purchasing a lithium battery, please add the corresponding product "Bebat Leapton EL-A05 5.12 kWh environmental levy" according to the number of batteries you are ordering. Otherwise, we will recalculate and invoice the amount after purchase.
