Inverters
The basic element of the UPS system is the inverter, the converter processing DC to single or three phase AC voltage.

Inverters perform the function of AC voltage source, and in complex power systems also have filtration and stabilization functions, ensuring high quality power through dual energy conversion. Higher power inverters are manufactured as parallel structures.

BFI Inverters
The task of the uninterruptible AC power supply is to provide uninterruptible power to critical applications, with stabilized voltage parameters. Critical receivers are devices or entire systems that require an uninterrupted power supply due to the need to maintain continuity of technological processes (e.g. industry) or business (e.g., banks, telecommunications, etc.) and / or require the ideal power source for proper and reliable operation.

Photovoltaic Inverters
The EKO inverter converts the constant voltage from the solar panel to 230/400V AC voltage. It allows the electricity generated to be sold to a low voltage network. It can also be incorporated into an internal system, significantly reducing consumption of the power plant's network. We specialize in high-power solar systems and inverters used, for example, in small home systems. Because the high efficiency of the system depends largely on the quality and durability of the inverter, we use only high-quality components. The EKO inverter is equipped with network management functions, that enables compensation of reactive power in the grid.
