UP400
UP400
A 400 W portable hydrogen fuel cell generator weighing 21 kg, designed for field personnel needing to power laptops, radios, GPS units and other personal equipment. With a noise level of 45 dB and zero emissions, it suits both off-grid civilian use and military forward positions. It can be combined with batteries, solar panels or wind turbines to form a micro-grid.
UP1K
UP1K
A 1 kW portable generator delivering 1000 W at 24 V, weighing 27 kg. Designed for disaster relief operations, 5G telecoms tower backup and defence field use, it shares the same near-silent and zero-emission profile as the UP400 while providing enough power for larger communication and sensing equipment.
UP3K
UP3K
A 3 kW generator, scalable to 6 kW with two cells, built for defence and security field operations. It supports remote monitoring and control via IoT, multiple battery options and grid-drop detection for automatic alarm starts. A 19-inch rack integration kit is available for indoor and outdoor installations, and the UP3K is rated for 10,000 operating hours.
UPMobile
