- Solar and Fuel Cell Power supply for Lidar installed in a trailer
- Hybrid solution combining 125 W fuel cell and 1050 W solar modules with 440 Ah 24 V strong batteries
- Space for LiDAR device inside the trailer
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 Netbiter 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.
The trailer is designed to host a LiDAR device. It works with most LiDAR on the market like MeteoLaser, ZX and Windcube. 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).
