Presentation onduleur WKS CIRCLE

Discover the WKS EVO Circle, the new generation solar inverter that will transform your energy experience!
Thanks to its advanced MPPT solar charge controller, this inverter optimizes and regulates the DC power of your solar panels to efficiently charge your battery bank. You can say goodbye to low battery worries. Its transformer-free design ensures reliable power conversion, all in a compact form factor that fits any space.
With its built-in Wi-Fi feature, you can monitor your UPS from your mobile app, viewing and recording data to track its operating status. And for even more convenience, the UPS supports USB On-The-Go functionality, simplifying parameter rewrites, data downloads, and software updates.

Choose the WKS EVO Circle and enjoy smart, efficient and connected solar energy to simplify your daily life!

3 modes of operation

• Solar priority
• Solar and grid

- Battery charging current adjustment
- Ability to limit or prohibit charging via the network
- Input voltage from 110 to 280V (useful for fluctuating networks)
- Economic mode (limitation of self-consumption)
- Fine-tuning of battery charging characteristics
- Automatic restart in case of overload and over-temperature
- Possibility to limit battery discharge in order to preserve their lifespan
- Return voltage in configurable battery mode
- Low battery safety

zoom écranMulti-energy power supply


Example: for a consumption requirement of 3kW, you can have a configuration: 

  • 1 kW provided by solar energy
  • 2 kW supplied by batteries


This multi-power technique greatly reduces the battery fleet and extends its life.

This inverter accepts up to 6000 Wp of photovoltaic panels, and can connect to the grid or another renewable energy source if solar production is insufficient.


  • Residential, commercial and telecommunications 
  • Areas where electricity supply is unstable 
  • Areas that are not connected to the grid

Use in back-up mode


Utilisation en mode back-up

It is possible to use the inverter as a "back-up", without photovoltaic panels. In this mode, the UPS will act as UPS, protecting your devices from network outages.

The UPS thus protects computers and audio-visual equipment, or any other sensitive load by providing a stable current. It guarantees uninterrupted power supply to consumers.
The electricity produced from these pure sine inverters is stable. 

Possibility to protect only one or more rooms of your house through the distribution box.

Use in Off-grid mode

 Utilisation en mode Off-grid (hors réseau)

In this configuration, the inverter uses the panels to power consumers and to charge the batteries when the sun is present. The inverter draws current from the batteries to ensure the distribution of energy at night. 

There is the possibility of adding a generator set on the AC input of the inverter to ensure backup power.

Utilisation en mode hybride

Use in hybrid mode

The inverter takes power from the grid only if the batteries are empty and the solar production was not sufficient to cover the consumption.

The inverter never reinjects current into the electrical grid.

As with the "back-up" mode, it is possible to connect only part of your home installation to the inverter. Consumers connected to the inverter will always be powered, even in the event of a power outage. In addition, these consumers will be powered for free!

Convertisseur Pure SinusPure sine converter


The WKS is a pure sinusoidal voltage inverter (pure sine) that reproduces a current of quality similar to that of the public grid. It can be used to power all types of device.

Maximum charging current of 120A


The WKS incorporates an MPPT load controller developing a maximum load current of 120A

MPPT Controller

Régulateur MPPTThe WKS also has MPPT (Maximum Power Point Tracking) technology, that is, it is constantly looking for the maximum power point, which makes it possible to get the best performance from photovoltaic panels. In addition to providing an increase in energy to an installation, it optimizes battery charging and extends battery life. It scans the panel voltage to find the maximum power output point and is able to adapt the voltage provided by the panel to align with the voltage the battery can receive.

icone horlogePossibility to choose the operating mode via timer

You can determine how your device works with a timer. Set a time slot yourself in the settings.
Thanks to this setting, you set the priority of the output source of your inverter to, for example, choose to recharge your batteries during off-peak periods.
