The next-generation inverter


Enjoy continuous and reliable power whether the network is available or not. The energy produced by WKS inverters is oriented and used intelligently for optimal performance. All priorities can be defined by the user: use of batteries, solar or AC source (network or generator) In self-consumption, the energy produced by your panels is fluctuating and it does not correspond to consumption. The WKS inverter stores some of the solar production in the batteries for later use during the evening or night. In isolated sites, the WKS inverter can be plugged into a generator to charge the batteries if they are empty and there is insufficient solar production. This inverter is able to work with several different energy sources such as:

  • public network
  • photovoltaic panels
  • thermal generator
  • Batteries 


Microprocessor management directs energy according to production, consumption requirements and battery charging. It is possible to follow up in real time locally or remotely. The WKS inverter does not re-inject power onto the electrical grid.

3 modes of operation


  •  Solar priority 
  •  aid
  •  Solar and grid
 - Adjusting the battery charge current
 - Possibility of limiting or prohibiting the charge via the network
 - 90-450V input voltage (useful for fluctuating networks)
 - Economic mode (limitation of self-consumption)
 - Fine setting of battery charge characteristics
 - Automatic restart in case of overload and over-temperature
 - Possibility of limiting battery discharge in order to preserve their lifespan
 - Tension back in set-up battery mode 
 - Overload bypass (allows to pass on the network in case of peak consumption)
 - Low battery safety

Multi-energy power


Example: For a 3kW consumption need, you can have a setup: 

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


This multi-power technique greatly reduces the battery stock and extends its lifespan.

This inverter accepts up to 8000 Toilets of photovoltaic panels, and can connect to the grid or other 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


Use in back-up mode

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

The inverter protects computers and audio-visual equipment, or any other sensitive load by providing a stable current. It guarantees uninterrupted consumer power.
The electricity generated from these pure sinus inverters is stable. 

It is possible to protect only one or more rooms of your home through the distribution box.

Use in Off-grid mode (off-grid)

Use in Off-grid mode (off-grid)


In this configuration, the inverter uses the panels to power consumers and to charge the batteries when the sun is present. The inverter draws power from the batteries to ensure the distribution of energy at night. 
There is the possibility of adding a generator to the AC input of the inverter to provide backup power.

Use in hybrid mode


Use in hybrid mode

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

The inverter never re-injects power onto 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 if the electricity grid is cut off. In addition, these consumers will be fed for free!

Pure Sinus Converter

Pure Sinus Converter


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

Maximum charge current of 80A


The WKS incorporates two MPPT charging controllers each developing a maximum charge current of 80A

MPPT Regulator

MPPT Regulator

The WKS also has the MPPT (Maximum Power Point Tracking) technology, which means that it is constantly looking for the maximum power point, which allows to draw the best performance of photovoltaic panels. In addition to providing an increased energy to an installation, it optimizes the battery charge and extends their lifespan. It scans the panel voltage to find the maximum power output point and is able to adjust the voltage provided by the panel to align with the voltage the battery can receive.
