Inverters

An inverter is an essential part of any energy solution. The device converts direct current (DC) into alternating current (AC), making stored energy usable for machines, appliances and grid connections. At Frax you will find inverters designed specifically for professional and industrial applications. They play a central role in energy storage systems and battery solutions, and are distinguished by reliability, efficiency and ease of use. With this, we supply inverters that are fully integrated into our Battery Energy Storage Systems (BESS).

What does an inverter do?

An inverter converts direct current, as it comes from batteries or solar panels, into usable alternating current. This process is crucial because virtually all electrical appliances and installations run on alternating current. In addition, inverters make it possible to feed energy back into the grid. In the context of renewable energy and battery storage, inverters are indispensable: they ensure that stored energy can be used efficiently, safely and reliably.

Inverters for battery energy storage

In large-scale energy storage, inverters play a key role. In combination with battery containers, cabinets or indoor solutions, they form the heart of a BESS installation. They take care of energy conversion and enable smart connections to energy management. With an advanced energy management system (EMS), inverter deployment is optimally matched to energy demand, effectively handling peak loads and grid congestion.

The advantages of Frax inverters

Frax inverters are designed for professional applications and are distinguished by their efficiency, reliability and ease of use. Thanks to their plug-and-play configuration, they are easy to install and scalable to use, whether for a temporary construction site or a permanent corporate project. Whereas standard inverters are often aimed at small-scale use, Frax solutions are designed to handle large capacities, thus contributing to emission-free and future-proof energy supply.

Applications of professional inverters

Professional inverters come in handy in numerous situations. Consider emission-free construction sites, where electrical machines are powered without diesel generators. They are also indispensable on industrial sites and in industrial plants, for example for smoothing out peak voltage or as an emergency supply in the event of a power failure. With inverters from Frax, you benefit from a stable power supply, even in situations where the grid is heavily loaded.

Why Frax for industrial inverters?

Frax offers a complete range of energy solutions in which inverters always play a central role. Our systems are designed to completely unburden installers and companies: from indoor to container solutions, supported by smart EMS technology and expert service. With this, you don't just choose an inverter, but a total solution ready for the future. Contact us today and find out how Frax supports your project with reliable and emission-free energy solutions.
