An A-level, DC battery

get thunderstruck.

Typical battery systems convert DC energy produced by solar panels into AC current and then use it to convert it back to DC current. This causes a lot of energy loss.

The iLubat is a full DC solution that stores energy in a more efficient way, without wasting  your valuable solar energy. For households without solar panel systems, we provide improved AC solutions to cope with dynamic energy tariffs.

Grid operator Fluvius wants to invest an additional 4 billion in electricity grids

Grid company Fluvius wants to invest an additional 4 billion in the Flemish distribution networks for electricity between next year and 2032. To ensure that by 2030 we can continue to smoothly accommodate up to 1.5 million electric cars, massive numbers of heat pumps and solar panels, and rising consumption in industry, Fluvius is proposing to reinforce 40 percent of the low-voltage grid, 13 percent of the medium-voltage grid, and one-third of the distribution cabins that distribute power in the streets over the next ten years. Investments in the gas grid will then be phased out over the next decade.
