The stand-alone power supply system is especially made to supply and host a LiDAR device. The power supply system is recommended for all climates, except artic conditions with only little hours of sunshine.
The system combines a powerful Methanol-based EFOY Pro fuel cell and three solar modules. The system is equipped with two 28 liters fuel cell cartridges.
In order to monitor and control the EFOY Pro fuel cell, a GSM-2-GPIO modem is installed. Hence, the modem sends current system data to the web viewer. The frequency can be configured via the web viewer. Alarms, such as low fuel or low battery voltage, can be configured. Thus the system automatically informs via email or SMS, in case of triggering alarms. At default settings, the typical monthly data traffic (GPRS) is approx. 2 MB.
The trailer is designed to host a LiDAR device. It has a removable hatch on its top for the laser beam.
In very remote sites the trailer can be moved by a helicopter using straps or lifting brackets (optional).
