Photovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. The photovoltaic effect refers to photons of light exciting electrons into a higher state of energy, allowing them to act as charge carriers for an electric current. The photovoltaic effect was first observed by Alexandre-Edmond Becquerel in 1839. The term photovoltaic denotes the unbiased operating mode of a photodiode in which current through the device is entirely due to the transduced light energy. Virtually all photovoltaic devices are some type of photodiode.

Solar cells produce direct current electricity from sun light which can be used to power equipment or to recharge a battery. The first practical application of photovoltaics was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. In this case an inverter is required to convert the DC to AC. There is a smaller market for off-grid power for remote dwellings, boatsrecreational vehicles, electric cars, roadside emergency telephones, remote sensing, and cathodic protection of pipelines

Who are Energija?

Energy Storage Life Cycle Based on depth of Discharge


After 15 years of research and development, redT has developed a new and proprietary energy storage technology which enables the efficient and sustainable storage of electrical energy in liquid form.  The multi-valent properties of the Vanadium Redox electrolyte are used to provide a storage medium of virtually unlimited life with a redT machine able to last 25+ years.

Combine this with very low maintenance requirements, and redT energy storage machines are able to deliver some of the lowest levelised cost of storage (LCOS) results in the industry.

Since signing a manufacturing contract with Jabil, a world leading manufacturer, redT has developed containerised, modular energy storage machines. The standardised modular design has allowed the size and cost of the energy storage machines to be significantly reduced whilst increasing their functionality and usability. The use of a modular system allows for easier installation, transportation, maintenance and decommissioning.

Why use Energija energy storage?

Use redT energy storage in a range of grid-connected or off-grid/weak grid scenarios. Our machines can be coupled alongside renewables such as solar and wind, allowing you to maximise your energy increase utilisation or alongside diesel generators (or a combination of the two), increasing genset efficiency or functioning within a mini-grid set-up.
