Jak to začalo | Resacs

How it started

At the beginning of 2022, the idea of founding a company was born, so Resacs, s.r.o. was established. We started together with two friends in a family house in Otrokovice by manufacturing batteries for scooters, caravans and boats. Eventually, an e-shop was created and the sale of batteries started online. Later we also started to deal with PV installations.

První stěhování | Resacs

The first moving

As the number of orders increased, the production facilities had to be addressed. We found a refuge in the industrial area TOMA in Otrokovice. We were approached by several customers and the demand grew so much that it was necessary to increase the number of employees. At that time, there were 12 of us working in the company. This is also where our first designs and implementation of battery storage for PV plants originated.

Expandujeme dál | Resacs

Expanding further

With the arrival of the first major partner, production took off and after eight months it was necessary to increase production capacity again. This time we found a refuge in the TOS premises in Hulín. Staff had to be doubled, production processes had to be improved and new operating systems had to be introduced. We innovated concepts in battery storage design and control. During this time, we also succeeded in designing our first large battery storage facility.
