The inverter generation

Enjoy a continuous supply and reliable q EU network is available or not. The energy produced by the inverters WKS is oriented and used intelligently for optimal performance. All priorities can be defined by the user: use of batteries, solar or the AC source (generator or network) Consumption, energy produced by your panels is in flux and is not for consumption. The WKS UPS stores part of the solar production in batteries for later use during the evening or night. In remote areas, the WKS inverter can be connected to 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 


Management by microprocessor directs energy based on production, consumption needs and the State of charge of the batteries. It is possible to carry out a follow-up in real-time locally or remotely. Inverter WKS feeding power into the grid.

3 operating modes

  •  Solar priority 
  •  Relief
  •  Solar and network
 -The battery charge current setting
 -Possibility to limit or ban the load via the network
 -Input voltage of 110-280V (useful for fluctuating networks)
 -Economic mode (limitation of the auto consumption)
 -Fine tuning of the characteristics of the batteries
 -Automatic restart in case of overload and overtemperature
 -Possibility to limit the battery discharge in order to preserve their life expectancy
 -Return mode adjustable battery voltage 
 -Overload Bypass (allow to pass over the network in case of peak consumption)
 -Low battery safety

Power multi-energie


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

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


This technique of multi power allows to strongly decrease the Battery Park and extend its life.

This inverter accepts up to 4000 Wc of photovoltaic panels, and can connect to the network or another source of renewable energy if the solar production is insufficient.



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

Use back-up modeUse back-up mode

It is possible to use the ups as a "back-up", without solar panels. In this mode, the UPS will ensure the role of UPS to protect your devices from the network cuts.

The UPS protects computers and equipment audio-visual or any other sensitive charge by providing a stable current. It guarantees a power supply of consumers.
The electricity produced from these inverter pure sine is stable. 

Possibility to protect one or more rooms in 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 panels to supply consumers and to charge the batteries when the Sun is present. The inverter draws aware of batteries to ensure the distribution of energy at night. 

There is possibility to add a generator on the inverter AC input to ensure a backup power supply.

Use in mode hybridUse in mode hybrid

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

The inverter back never power on the grid.

As for the "back-up" mode, it is possible to connect as a part of your installation domestic on the inverter. Consumers connected to the inverter will be always powered even if the grid power d e distribution. In addition, these consumers will be powered for free!

The models WKS 4.0 and 5.0 (with a respective capacity of 4 and 5 kVA) can connect in parallel so as to add their power. You can connect up to 4 devices in parallel to achieve a power of 20 kVA.

Converter Pure sine

Converter Pure sine

The WKS is an inverter pure sine voltage (pure sine wave) that reproduces a stream of similar quality to that of the public network. It can be used to power any device.

80A maximum load current

The integrated WKS a controller of load MPPT developing a maximum load of 80 current has

MPPT regulatorMPPT regulator

The WKS has also the MPPT (Maximum Power Point Tracking) technology is to say he's looking at all times the maximum power point, which allows to get the best performance of the photovoltaic panels. In addition to providing increased energy to a facility, it optimizes the battery and prolongs their life. He scans the on-board tension to find the point of maximum power output and is capable of adapting the power provided by the Panel to align the voltage that the battery can receive.

Pas encore reçu, Mise en œuvre a priori simple La notice demande à être plus précise, exemple sur les différents fonctionnements possible; en autonome sans réseau EDF, comment interdire la recharge batterie sur réseau, comment interdire le réseau d’alimenter la charge, etc… Le produit n’aura pas forcément le dernier firmware J’ai hâte de voir son comportement. Etc…

A very complete design of a battery charger (AC net and sun panels) with versatile preset parameter for different battery types and brands. It's also a versatile inverter setup UPS modes and priorities. The cable connections are easy accessible. Weaker points are the cable access holes. A cable gland instead of the star openings would be a more appropriate assembly solution. The work setup via communication via the integrated (but removable) panel needs a lot patience, onthe other hand is the blue tooth link very comfortable in use. A lot of value for the price.
