This solar self-consumption kit with storagecombines high-performance photovoltaic panels, a reliable hybrid inverter and a high-capacity lithium battery.
It not only allows you to consume your solar production directly, but also to store the surplus for use at night or during peak consumption periods.
As it operates without feeding into the grid, it does not require a Consuel certificate, which simplifies the administrative process.
Key advantages:
- Optimised solar energy production for self-consumption.
- Battery storage so you can consume your electricity at any time.
- Powerful and easy-to-install hybrid inverter.
- No electrical inspection required thanks to the absence of grid injection.
- Scalable solution that can be adapted to your specific needs.
Estimated production and savings:
Each solar panel has a power output of 450 Wp. With this kit, you can generate around4,895 kWh per year, representing a potential saving of around£1,468.50. These estimates are provided for information purposes only for central France, based on a reference price of£0.30/kWh.
Why choose this kit?
- Complete solution including panels, inverter and 15 kWh lithium battery.
- Reliable components selected from the best brands.
- Significant reduction in your energy bill.
- Simplified installation without heavy administrative constraints.
- Option to customise the kit (add panels or batteries).
This kit includes
The basic kit includes 10 solar panels, a WKS EVO Circle PRO 6.5 kVA single-phase inverter, solar cables to connect the panels to the inverter, and an optional panel mounting system. (The mounting system, cabling and protective devices 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.

Energy independence / reduced dependence on the grid
The kit allows you to generate your own electricity and store any surplus, making you less vulnerable to fluctuations or outages in the public grid.
Long-term savings
Although the initial investment is high, over several years, with the estimated savings, the return on investment can be attractive.
Combined production and storage
Having a battery allows you to use electricity even when there is no sun (at night or on very cloudy days). This improves self-consumption.
Sustainability and environmental friendliness
Reduced carbon footprint, fewer emissions linked to electricity production via conventional sources.
Battery with good lifespan, certified components.

| The WKS Evo Circle PRO 6.5 kVA 48 V 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. |
The WKS Evo MAX II 10 kVA 48 V is a high-performance, modular hybrid solar inverter designed for high-demand residential or semi-collective installations. It stands out for its high power, operational flexibility and intelligent interfaces. |

This LiFePO₄ battery offers a nominal capacity of 15kWh (with an actual usable capacity of ~16kWh) for a voltage of 51.2V and 314Ah, presented in a modular, stackable and mobile format.
Technology and sustainability
• Uses prismatic CALB (or BYD, depending on version) cells, renowned for their reliability, safety and long service life (up to 6,500 cycles, or approximately 12 years).
• Features an integrated smart BMS (battery management system), ensuring increased protection and
Design and compatibility
• Designed to be stackable, it allows the total capacity to be increased up to 61.44 kWh by combining several units.
• Compatible with major inverters via RS485, CAN, or RS232 for easy integration into various systems (residential, commercial, or off-grid).
• CE-certified product, suitable for long-lasting installations with a 10-year warranty.
• Sold without mounting bracket — to be purchased separately.
Use
This battery is ideal for storing solar (or other) energy, providing reliable energy autonomy. It can power a home for self-consumption, be deployed in off-grid systems, or serve as a backup power supply. Its modular design allows the capacity to be adjusted as needed. Integration is via standard interfaces, facilitating monitoring and management via the BMS.


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 Delong Top 15 kWh battery is subject to a mandatory environmental levy.
An amount of€342.47 excluding VATmust 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.
Important: When purchasing a lithium battery, please add the corresponding product "Bebat Delong Energy environmental levy - 15kWh" according to the number of batteries you are ordering. Otherwise, we will recalculate and invoice the amount after purchase.
This tax only applies to Belgian customers and only concerns Pylontech batteries.
