For safety reasons an uninterrupted power supply is needed during construction phase and longer maintenance periods for obstacle lights and pumps. Power demand obstacle lights: Between 50 and 100 W Power demand pumps: Approx. 25 W
During construction and maintenance work, no grid access is available but operation safety for obstacle lights and pumps still has to be guaranteed. Autonomy of up to three months is required, resulting in high service and operating cost for batteries and generators and high maintenance effort.
Provide reliable off-grid power with a maintenance free and environmentally friendly EFOY Pro fuel cell, which will power your application for several weeks or even months without ever requiring user intervention.
