Complete energy autonomy, even off-grid This kit is designed to operate in completely autonomous mode. It generates electricity (via the panels) and stores it in OPzV batteries to power your installation, even without the grid. |
Flexibility and scalability
If your energy requirements increase over time (extension, new equipment), this type of kit is often modular (addition of modules, storage expansion) depending on the design of the system. |
|||
|
Reliable, long-lasting storage capacity OPzV batteries (gel electrolyte / tubular) are renowned for their longevity and tolerance of frequent cycling. They are well suited to demanding installations (Class 4) where energy demand is high. |
Resilience to outages & isolation In the event of a power failure or absence from the grid, this system continues to supply electricity to critical equipment (lighting, refrigerator, pump, etc.). |
|||
|
Class 4" solution for intensive use The term "class 4" indicates that this kit is designed for significant loads: complete domestic use, small workshops, pumps, major electrical equipment. This is not a minimalist solution. |
Long-term profitability and protection against price rises Even if the initial investment is substantial, you'll reduce your electricity costs over the long term. Every kilowatt produced "at home" protects you against price increases. |

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.

| The WKS Evo Circle 5.6 kVA 48 V for "compact format + 6.5 kW + MPPT 120 A" The Circle PRO aims for more compact/lightweight integration (12 kg), with 6.5 kW power, 1 MPPT, an equally wide PV input (90–450 V, Voc 500 V) and an MPPT 120 A. It highlights the "dual output" (critical/secondary loads) and parallelisation of up to 6 units (39 kW announced). |
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. |

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 Pylontech US5000 battery is subject to a mandatory environmental levy.
An amount of €114.73 excluding VAT must be added for each battery purchased, as a direct contribution to Bebat, the organisation in charge of managing batteries and accumulators in Belgium. This measure complies with current Belgian environmental legislation.
Please note When purchasing lithium batteries, please add the corresponding product "Environmental contribution Bebat Pylontech US5000" according to the number of batteries you order. Otherwise, we will recalculate and invoice the amount after the purchase.
This tax only applies to Belgian customers.

To help your customers visualise what this kit can actually power, here are some scenarios:
| Use / context | Typical need covered | Remarks & limits to be specified | |||
| Isolated house or chalet in an unconnected area | Complete power supply for a dwelling: lighting, household appliances, small appliances, pump, light heating (low-power electric), etc. | Need to be sized according to peaks (heating, oven) - often certain heavy loads need to be planned or as back-up. | |||
| Farm or agricultural operation | Irrigation pumps, ventilation, small workshops, greenhouse lighting, water pumps, etc. | This kit can ensure the operation of critical systems, even if the mains supply is absent. | |||
| Isolated technical site / service room |
Technical substations, monitoring rooms, relay stations, stand-alone equipment |
Ideal for installations where reliability is paramount and access to the network is costly or impossible | |||
|
Mixed use: connected to the grid + stand-alone backup |
The kit operates in hybrid mode: when there's sunshine, the energy is used or stored; in the event of a grid failure, the system switches to the OPzV batteries |
Ideal for areas with frequent power cuts or for securing critical circuits |
|||
|
Light industrial use / workshop |
Light machinery, power tools, lighting, computers, controls |
Bearing in mind peaks and surges in consumption, careful sizing is required |
|||
|
Future expansion / gradual ramp-up |
Initially cover a moderate need, then add other modules or batteries as needs grow |
This "class 4" kit is often sized for margin and growth, so it's a good starting point. |
