PATENTED Cooling system

Star Q energy storage has no fans, but features a patented cooling system that brings a range of benefits:

longer battery lifespan (cells maintain optimal temperature at all times),
quieter operation (fans are noisy),
less maintenance (no moving parts, reducing the chance of failure),
lower energy consumption for cooling,
heat is dissipated naturally (through special materials and enclosure design).

Importance of IP67 protection

Even more efficient

The STAR Q energy storage not only stores electricity but also ensures its optimal utilization. The PCS + DCDC 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.

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.
