Transformers and isolators are essential components for operating your photovoltaic system safely, efficiently, and in compliance with standards. They play a key role in voltage adjustment, galvanic isolation, and electrical separation of system parts. This way, your system is protected from damage, operational safety is increased, and stable yields are ensured. At Green-Future.at you will find a carefully selected range of transformers and isolators that are optimally matched to your inverters, solar panels, and storage solutions.

How transformers work

In photovoltaic systems, transformers are responsible for increasing or decreasing voltages to adapt the generated solar power to the requirements of your home grid or grid feed-in. For example, in stand-alone systems with off-grid inverters, the voltage is provided for specific consumers or galvanically isolated to meet safety requirements. High-quality transformers help minimize losses and increase the efficiency of your PV system.

Isolators for maximum safety

Isolators ensure the electrical separation of system parts and prevent dangerous short circuits or electric shocks. They protect cables and wiring from mechanical stress and environmental influences. Especially in complex PV systems with multiple circuits, storage solutions, and backup systems, reliable isolators are indispensable for safely connecting all components. Together with suitable fuses and switchgear, they form the foundation of safe system operation.

Diverse applications

Transformers and isolators are used in various system types: from grid-connected systems to independent off-grid setups. Particularly in commercial projects, large rooftops, or ground-mounted systems, they play an important role in safe voltage adjustment and isolation. Combined with hybrid inverters and battery storage, they ensure your self-generated solar power is always optimally utilized.
