How it happened

The project story

The challenge was to provide a fully autonomous power supply for the furniture workshop due to a lack of access to the power grid. All production machinery and electrical loads had to rely entirely on power from the photovoltaic system and the battery, without a backup power supply from the grid.

We installed an off-grid photovoltaic system with a Deye hybrid inverter and an energy storage battery, tailored to the needs of the furniture workshop. This solution allows the solar energy generated during the day to power the machines directly, while any excess is stored in the battery and used when there is insufficient sunlight or outside of daylight hours.

Since it was put into operation, the plant now has its own sustainable energy source, which ensures the normal operation of the equipment and allows for better production planning. The battery serves as a power reserve and ensures more stable system operation during periods of variable sunlight.
