The WKS EVO Circle is equipped with an MPPT solar charge controller that maximizes and regulates the DC power of the solar panel to charge your battery bank.
The transformerless design allows for reliable power conversion in a compact size. The new generation of WKS has built-in Wi-Fi function, mobile monitoring can be done through mobile apps. The data can be viewed and stored in the inverter, which is convenient for tracking the operating status of the inverter. It also supports USB On-The-Go for easy rewriting of internal settings, data downloads and software updates.

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:Shine the color of your choice up and down in the circle.

Bluetooth communication (WatchPower)

Set up your inverter and your installation, check your production and record your data from your smartphone !

The WKS Evo's Bluetooth application gives you easy access to all the information of your installation.

An example of the available pages of the application is given in the product images.

3 operating modes

- Rescue
- Solar and grid


- Adjustment of the battery charging current
- Possibility to limit or prohibit the load via the network
- Input voltage from 110 to 280V (useful for fluctuating networks)
- Economy mode (self-consumption limitation)
- Fine tuning of battery charging characteristics
- Automatic restart in case of overload and overtemperature
- Possibility to limit the battery discharge to preserve their life
- Return voltage in battery mode can be set
- Low battery security

Multi-energy supply

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

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

This multi-powered technique greatly reduces the number of batteries and prolongs their life span.

This inverter accepts up to 6000 Wp of photovoltaic panels, and can be connected to the grid or to another renewable energy source if the solar production is insufficient.

Applications:

• Residential, commercial and telecommunications
• Areas with unstable electricity supplies
• Areas that are not connected to the network

Use in back-up mode

It is possible to use the UPS as a "back-up", without photovoltaic panels. In this mode, the UPS will act as a UPS, to protect your appliances from grid outages.

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

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

Use in off-grid mode

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

A generator can be added to the AC input of the inverter to provide backup power.

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 feeds power back into the grid.

As with the "back-up" mode, it is possible to connect only a part of your home installation to the UPS. The consumers connected to the inverter will always be supplied, even in case of a power failure of the distribution network. Moreover, these consumers will be supplied free of charge!

Pure Sinus converter

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

Maximum load current of 120A

The WKS integrates a MPPT charge controller developing a maximum charge current of 120A

MPPT controller

The WKS also features MPPT (Maximum Power Point Tracking) technology, which means that it constantly searches for the maximum power point, thus enabling the best performance from the photovoltaic panels. In addition to providing an increase in energy to an installation, it optimizes the charge of the battery and extends their life. It scans the panel voltage to find the maximum power output point and is able to adapt the voltage supplied by the panel to align with the voltage the battery can receive.

Possibility to select the operating mode via timer

You can determine the operating mode of your device with a timer. You can set a time slot in the settings.
Thanks to this setting, you can define the priority of the output source of your UPS to, for example, choose to recharge your batteries during off-peak periods.
