The new-generation inverter

Benefit from continuous, reliable power, whether the grid is available or not. The energy produced by WKS inverters is directed and used intelligently for optimum performance. All priorities can be set by the user: use of batteries, solar or AC source (grid or generator). In self-consumption, the energy produced by your panels fluctuates and does not correspond to consumption. The WKS inverter stores part of the solar output in the batteries for later use during the evening or night. On isolated sites, the WKS inverter can be connected to a generator to charge the batteries if they are empty and solar production is insufficient. This inverter is capable of working with several different energy sources, such as :

• public grid
• photovoltaic panels
• thermal generator
• batteries

Microprocessor-based management directs energy according to production, consumption needs and battery state-of-charge. Real-time monitoring can be carried out locally or remotely. The WKS inverter does not feed power back into the grid.

3 operating modes

• Solar priority
• Backup
• Solar and grid

Multi-energy power supply

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

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

This multi-supply technique greatly reduces the number of batteries required, and extends their lifespan.

This inverter accepts up to 1500 W of photovoltaic panels and can be connected to the grid or to another renewable energy source if solar production is insufficient.

Applications :

• Residential, commercial and telecommunications
• Areas with unstable electricity supplies
• Areas not connected to the grid

Use in back-up mode

The inverter can be used as a back-up without photovoltaic panels. In this mode, the UPS takes on the role of UPS, protecting your appliances from grid outages.

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

You can protect one or more rooms in your home via the distribution box.

Off-grid operation

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

A generator can be added to the inverter's AC input to provide emergency power.

Hybrid operation

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

The inverter never feeds power back into the grid.

As with the "back-up" mode, you can connect only part of your domestic installation to the inverter. Consumers connected to the inverter will still be powered, even in the event of a mains power cut. What's more, they'll be supplied free of charge!

Pure Sine converter

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

Maximum load current 60A

The WKS integrates an MPPT charge controller developing a maximum charge current of 60A.

MPPT controller

The WKS also features MPPT (Maximum Power Point Tracking) technology, i.e. it constantly searches for the maximum power point, enabling the best performance from photovoltaic panels. As well as providing a boost in power to an installation, it optimizes battery charging and extends their lifespan. It scans the panel voltage to find the maximum power output point, and is able to adapt the voltage supplied by the panel to match the voltage the battery can receive.
