Inverter WKS feeding power into the grid

3 operating modes

  1. Solar priority
  2. Relief
  3. Solar and network
Power multi-energy

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

  1. 1 kW provided by solar energy
  2. 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 3000 Wc of photovoltaic panels, and can connect to the network or another source of renewable energy if the solar production is insufficient.

  1. Residential, commercial and telecommunications
  2. Areas where electricity supply is unstable
  3. Areas that are not connected to the network
Use 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)

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 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 feeding power into 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

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 WKS integrates a charge of MPPT controllerdeveloping a load battery max 60 current has as well as a charge controller network for a cumulative total of 140A 80A.

MPPT 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.
