What kind of application is it?

We use an EFOY Pro 800 Duo fuel cell for the electrical supply of a water meter at a drinking water source. The fuel cell is integrated as a complete solution in an EFOY ProCabinet 2060A. The customisable EFOY ProCabinet also offers enough space to accommodate our own measurement equipment.

Which energy problems or which challenges had to be solved?

Solar cells are often used to power our meters. Due to the location of the drinking water source in the forest, solar cells were not an option in this case. We were faced with the challenge of finding a power supply solution that could be used in water conservation areas and provide us with self-sufficient, off-grid power. In addition, our measuring instruments needed to be protected against vandalism.

Why did you choose the EFOY Pro?

We were looking for an off-grid energy solution with a long self-sufficiency period and as little maintenance as possible. Due to its size, the ProCabinet offers the possibility of accommodating all components required on site in a single control cabinet. In addition, the EFOY fuel cell does not require any maintenance.

The solution:
EFOY Pro 800 Duo

The ideal energy solution for off-grid applications: The EFOY Pro 800 Duo in combination with the customizable EFOY ProCabinet 2060A offers months of autonomy and enough space to accommodate your own measurement technology.

Power requirement: 20 W
Nominal voltage: 12 V
Energy capacity: 60 kWh

How did you integrate EFOY Pro into your installation and how many EFOYs do you use?

The EFOY Pro 800 Duo is integrated into a cabinet with two lead batteries and two M28 fuel cartridges. This constellation is sufficient for several months of autonomous operation.

How many EFOYs do you use, or do you combine other energy sources too?

At this location, an EFOY Pro serves as an energy source. Solar modules cannot be used here.

What benefits does the EFOY Pro bring you in your application?

Due to the long self-sufficiency times we save ourselves service times. Failures due to bad weather can be avoided. The EFOY ProCabinet offers us the ability to provide a reliable self-sufficient power supply for our measurement technology in a water protection area.
