The next-generation inverter

 

WKS inverter with 2 integrated MPPT controllers

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 set by the user Use of batteries, solar or AC source (network or generator) 

Self-consumption, the energy produced by your panels is fluctuating and 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 ensure the charge of the batteries if they are empty and the solar production is insufficient. 

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: Off-grid mode (off-grid)
  •  Relief: "back-up" mode
  •  Solar and network: "hybrid" mode
  •  
 - Adjusting the battery charge current
 - Possibility of limiting or prohibiting the charge via the network
 - Entry voltage from 90 to 280V (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 
 - Joint charge from the solar and the possible network
 - 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 3000 Toilets of photovoltaic panels, and can connect to the grid or other renewable energy source if solar production is insufficient.


Applications:

 

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

Use in back-up modeUse 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 does not re-inject 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!
The WKS 4.0 and 5.0 models (with a power of 4 and 5 kVA respectively) can connect in parallel to add up their power. You can connect up to 4 devices in parallel to reach a power of 20 kVA.


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 180A

Maximum charge current of 180A

 

The WKS incorporates an MPPT charge controllerdeveloping a max 120A battery charge current and a 60A network charge controller for a cumulative total of 180A.


2 MPPT Regulators

2 MPPT Regulators

 

The WKS also has THE MPPT (Maximum Power Point Tracking) technology, i.e. 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 it with the voltage the battery can receive.
