iLumen launches battery for solar modules

PV module specialist iLumen from Tessenderlo (Belgium) has presented its self-developed battery for solar systems. The iLubat, as the battery is called, will be brought to the market this spring. According to the developers, the payback period is less than five years. Flemish Energy Minister Bart Tommelein reacts enthusiastically: “This type of innovation contributes to the stability of our future electricity grid.”

Tommelein iLubat

The company Futech was founded in 2008 by engineers Pieter Vangeel and Ismaël Ben-Al-Lal with the focus on green energy. In 2012, engineering company with own R&D-department iLumen was founded. In the meantime, they already developed a number of innovations, good for five patents. Perhaps the best known is the PIDbox, which ensures higher efficiency and longer life of the solar modules. The system has now found its way to 40 countries.


Yesterday, iLumen presented its latest innovation, the self-developed battery system iLubat. It is of course not the first battery for solar modules on the market, but it does have a number of features that provide a unique solution in the market. “The system is currently in the final test phase. We hope to be able to put it on the market this spring”, says Ismaël Ben-Al-Lal.

We save you the technical details, but it comes down to the fact that the electricity grid is much less loaded at peak times. The battery charges when there is a peak in electricity production, to discharge it in the evening for self-consumption or on the grid.

More stable grid

“The grid operators such as Infrax and Eandis are going to experience much less fluctuations in the case of beautiful weather and low consumption”, says Pieter Vangeel. “The consumer saves on the prosumers rate, the tax for the use of the electricity grid. This is because the battery requires a much lighter inverter (1.5 kW). As a result, the consumer earns the iLubat back in less than five  years”, says Vangeel.

Minister of Energy Tommelein reacts enthusiastically. “It gives consumers more freedom to manage their own electricity. It also ensures greater stability on the electricity grid of the future.”

Charging post

On the development table of iLumen, there currently is a so-called bi-directional charging post, which allows charging and discharging electric vehicles for home use. “In this way the batteries of electric vehicles can be used as a buffer. Seventy percent of residential energy consumption takes place when residents are at home. In this way, employees can recharge their vehicle at work via the overproduction of the solar modules and can discharge them at home. You can view it as an unsubsidised incentive to drive electrically”, explains Ismaël Ben-Al-Lal.
