It is a radio-relay communication application which is located in the forest. Two EFOY Pro 2400 Duo (corresponds to latest fuel cell generation EFOY Pro 2800) supply two Cambium TP600s, a Cisco catalyst switch and several monitoring devices.
The main problem was to solve the back-up energy source. The power supply from the grid was not guaranteed and switched off from time to time. In the past we used diesel generators as a back-up power source. They could provide about 1-2 weeks of standalone operations. With EFOY Pro the autonomy can be expanded at least to one year.
“50 times longer period of autonomous power”
The EFOY Pro fuel cells provide a 50 times longer period of autonomous power supply without service. Moreover it is also very easy to maintain.
Mr Kirill Ettenko, ISP ARBUZ Co. Ltd.
Both EFOY Pro fuel cells are connected in parallel with an inverter, charging one battery. Additionally we have installed a Cluster Controller CC1. The battery works as a back-up power.
We use two EFOY Pro fuel cells on a distant object. We do not use any other alternative power sources.
If the main power goes down, we are sure that there will be no idle in our communication services. Even a single hour of idle is very expensive in communications.
