Fuses
Fuses are an indispensable part of any electrical installation. They provide vital protection against the risk of fire and other disasters caused by electrical overloads. At Offgridtec, you have a wide choice of PV fuses so that you can also find the perfect solution for your application. Discover the functionality and special features of our fuses and benefit from the safety and reliability of Offgridtec products today!
What are fuses for?
Fuses are an essential part of any electrical installation to protect cables, wires and appliances from short circuits. They interrupt the circuit when a certain current is exceeded, thereby reducing the risk of injury to people and damage to equipment.
Fuses are found in almost all switching networks, including photovoltaic systems, e.g. between the solar module and the controller or between the charge controller and the battery. Investing in the right fuses can save you time, money and trouble in the long run.
Distinctions between fuses
Fuses are distinguished by three features in particular:
- Type
- Rated current and
- Tripping characteristics
There are two common designs for fuses:
- With a fuse, the overvoltage causes the conductive element of the fuse to melt. This interrupts the current flow. The fuse is therefore destroyed by a single blow and must then be replaced.
- Fuses with a switch function automatically switch off the current flow in the event of overloads and short circuits and can then be switched on again manually.
The rated current indicates the maximum amperage (A) that should be safely drawn from the energy source. It is important that the energy source can deliver at least the required amperage. Otherwise, there is a risk that the line will be damaged.
The tripping characteristic is usually noted directly on the component by a letter. Each characteristic type provides concrete information about the overload and

FAQ
- What are the advantages of fuses? Fuses protect equipment from overheating and short-circuits by interrupting the flow of current for a certain time when a specified current is exceeded.
- How do fuses work? There are different types of fuses and therefore different ways they work. For example, the conductor may melt if it overheats, in which case the fuse must be replaced. However, there are also fuses with automatic disconnection that can be reused afterwards.
- Is surge protection mandatory for PV systems? Since 14.12.2018, the installation of surge protection in photovoltaic systems has been mandatory. This applies both to new buildings and to extensions or renovations of solar systems.
- What is a flat fuse? Flat fuses are designed for particularly low voltages, which are normally used in motor vehicles. The current rating of flat fuses is indicated by the colour of the housing. These fuses are ideal for controlling and protecting circuits from overcurrent and short circuits.
