The new-generation inverter

Enjoy 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 defined 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

1) Solar priority

2) Emergency

3) Solar and grid

  • Adjustment of battery charging current
  • Possibility of limiting or prohibiting charging via the grid
  • Input voltage from 90-450V (useful for fluctuating grids)
  • Economy mode (limits self-consumption)
  • Fine-tuning of battery charging characteristics
  • Automatic restart in the event of overload and overtemperature
  • Possibility of limiting battery discharge to preserve battery life
  • Return voltage in battery mode configurable
  • Overload bypass (allows switchover to grid in the event of peak consumption)
  • Low battery safety device

Use in back-up mode

Utilisation en mode back-up

The UPS 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.

Utilisation en mode Off-grid (hors réseau)

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

Utilisation en mode hybride

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!

Convertisseur Pure Sinus

Pure Sine converter

The WKS Evo MAX II 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 150A

The WKS Evo MAX II integrates two MPPT charge controllers, each delivering a maximum charge current of 150A.

MPPT controller

Régulateur MPPT

The WKS Evo MAX II also features MPPT (Maximum Power Point Tracking) technology, i.e. it constantly searches for the maximum power point, enabling maximum 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.
