Precise water cooling system

The Star H energy storage uses a water cooling system. It ensures optimal cell temperature and maximum operational efficiency. Let’s explore the additional benefits provided by precise water cooling:

longer battery lifespan (cooling prevents overheating),
high system efficiency (less energy is lost, system operates stably regardless of load),
reliable performance at high temperatures (ideal for industrial facilities and demanding environments),
less maintenance (liquid cooling is predictable and reliable),
temperature control for each cabinet.

Importance of IP65 protection

Even more efficient

The STAR H energy storage not only stores electricity but also ensures its optimal utilization. The PCS design allows energy from the solar system to be stored and used with minimal losses, resulting in higher self-consumption and less dependence on the electrical grid.

Storing excess generated energy and reducing the morning startup peak.
Almost lossless - the energy you store is returned to consumption to the greatest extent possible.
Unlimited expandability - supports connection of up to 10 cabinets, so it grows with your needs.
Future-ready - allows integration into microgrids and smart energy solutions.
Energy under full control - intelligent management ensures stable and efficient operation without unnecessary losses.
