Energy storage system
in a residential building?
YES, it pays off!
An energy storage system in a residential building is:
greater energy
self-sufficiency
lower
bills
protection against rising energy prices
power supply guarantee during outages
Benefits of installing an energy storage system
An energy storage system is a device that collects, accumulates, and stores electrical energy for later use. It works like a battery, operating independently of a photovoltaic installation. It charges from the grid during the lowest daily tariff period and releases energy during peak hours or power outages.

How does an energy storage system work?
The Marstek energy storage system is an intelligent and easy-to-use device that automatically charges during hours when electricity is cheaper.
At times of increased demand — for example, in the evening, when using household appliances, a TV, or a computer — the device releases the stored energy, reducing the amount drawn from the grid.
The system operates fully automatically and requires no maintenance — you just need to plug it in. It allows you to save energy even while living in an apartment building.

Wybrałem magazyn energii. Wszystko zostało mi szczegółowo objaśnione, sposób działania, skala oszczędności. Instalację dostarczono i zamontowano w uzgodnionym terminie. Wszystko przebiegło gładko i stosunkowo szybko.

Zainstalowanie magazynu energii w naszym mieszkaniu okazało się strzałem w 10. System działa bezobsługowo, jest zgrany z siecią. Nasze rachunki stały się niższe. Nie przejmujemy się zagrożeniami, czy awariami, czujemy się niezależni. Polecamy gorąco firmę OZEA, panowie sprawnie zamontowali nam system, wszystko wytłumaczyli. Formalności mogły początkowo przytłaczać, ale od razu poczuliśmy się zaopiekowani i udzielono nam odpowiedzi na wszystkie pytania.

FAQ
An energy storage system draws electricity from the grid and stores it in batteries. When there is a demand for power at night, during an outage, or when electricity prices are high, it releases the stored energy. The SMART system manages this energy efficiently.
The price depends on its capacity and technology. For apartments, the cost of purchase and installation is around 15,000 PLN.
Yes. The Marstek device was designed specifically for residents of multi-family buildings. It’s very easy to use — simply plug it into a socket. It doesn’t require photovoltaic panels or any electrical network modifications.
Modern energy storage systems last about 10 years, and some batteries, such as lithium-ion ones, even longer, with minimal capacity loss. They are maintenance-free and only require periodic technical inspections.
Yes. The Marstek system can reduce your electricity bills by up to 65% — it charges when power is cheaper and releases energy during peak hours. It doesn’t require solar panels, operates automatically, and provides backup power during outages.
No. The device charges directly from the power grid.
