The powerful WKS Evo MAX II is equipped with a 150A MPPT solar charger, a newly upgraded 5-inch color LCD display and a touch button. It can also access the data and save it in the inverter to make it easier to track the operating status of the inverters.

Three RGB light effects

• Circular scrolling: Fast scrolling of the color of your choice in a continuous circular motion.

• Wheel: Illuminates with twinkling lights in the color of your choice.

• Chasing: Illuminate the color of your choice from top to bottom in the circle.

Wifi Communication (WatchPower)

Set up your inverter and installation, check your production and save your data from your smartphone!
The WKS Evo's WiFi app gives you easy access to all the information about your installation.
An example of the available pages of the application is given in the product images.

The new generation inverter

Enjoy continuous and reliable power supply regardless of whether the network is available or not. The energy produced by WKS inverters is intelligently oriented and used 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 in the evening or at night. In an isolated site, the WKS inverter can be plugged into a generator set to charge the batteries if they are empty and 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 needs and the state of charge of the batteries. It is possible to carry out real-time monitoring locally or remotely. The WKS inverter does not re-inject current into the power grid.

3 operating modes

 1) Solar priority 

 2) Relief

 3) Solar and grid

Use in back-up mode

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

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

Possibility to protect only one or more rooms of your house through the distribution box.

Off-grid use

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

Use in hybrid mode

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

The inverter never re-injects current into the power 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 in the event of a power outage. In addition, these consumers will be fed for free!

Pure Sinus Converter

The WKS Evo MAX II is a pure sinusoidal voltage (pure sine) inverter that reproduces a current of similar quality to that of the public grid. It can be used to power all types of device.

Maximum charging current of 150A

The WKS Evo MAX II incorporates two MPPT charge controllers each developing a maximum charging current of 150A.

MPPT Regulator

The WKS Evo MAX II also has MPPT (Maximum Power Point Tracking) technology, that is, it constantly searches for the maximum power point, which makes it possible to get the best performance from photovoltaic panels. In addition to providing an increase in energy to an installation, it optimizes battery charge and extends their lifespan. It scans the voltage of the panel to find the maximum power output point and is able to adapt the voltage provided by the panel to align with the voltage that the battery can receive.
