EH Atlas · How PV works

PV system – from sunlight to energy use.

The entire technology is visible at once. Hover over a selected part and click to open a concise explanation in the separate right-hand panel.

Interactive: the green numbers 01–08 are part of the technical diagram. Click zones are transparent and only the relevant part is highlighted on hover.
PV system – panels, DC and AC technology, transformer, consumption, BESS and grid
Tip: simply hover over the technology. The panel opens only after a click and never covers the main diagram.
EH Atlas · How BESS works

BESS system – what is inside and how the components work together.

Click directly on the part of the technology you want to explore. As with PV, the main technical view remains clean and the detail opens in a separate right-hand panel.

Controls: click zones are invisible. On hover, the relevant part is gently highlighted; the detail opens only after a click.
BESS container – technical component overview
Hover over the container and click the component you are interested in.

The key insight

Energy has the greatest value at the right moment.

BESS stores energy when it is available and supplies it when the company needs it most.

How BESS shaves a demand peak.

When production demand exceeds the selected limit, BESS temporarily supplies the missing power. Production continues while grid demand remains more stable.

What happens when the grid fails.

Comparison of a standard outage with a system designed for backup operation. With the right technical solution, BESS isolates the selected part of the site from the grid and supplies critical loads.

Buy cheaper. Use at the right time.

BESS can store energy during lower-price hours and use it during higher-price hours. The economic result, however, depends on the price spread, efficiency, degradation and control strategy.

Excess PV generation does not have to go to waste.

When PV generates more than the business is consuming, BESS can store the surplus and use it later. The result is higher self-consumption and lower dependence on the grid.

How to charge a fleet without exceeding the grid connection limit.

When multiple vehicles connect at the same time in the evening, charging can create a sharp increase in demand. BESS can temporarily provide additional power and keep grid demand below the selected limit.

How BESS relieves the transformer during a peak.

If short-term site demand exceeds a safely selected transformer loading level, BESS can supply part of the power locally and reduce transformer loading.

How BESS helps maintain grid frequency.

When consumption temporarily exceeds generation in the system, frequency falls. When generation exceeds consumption, frequency rises. BESS can change its power very quickly and help reduce the deviation.
