Testimonial

Microscopist

I can power up the facility’s microscope with the NUE power backup unit in scenarios where we are experiencing a power outage, and all works proceed smoothly.

We are really very happy with the generators. One of the greatest advantages is that they are not generating any heat - making them invisible for night vision devices and drones.

NUE installed a 12V 400Ah battery in my remote cabin in to decrease my generator run time. The installation switches between solar panels and a gas generator to keep the battery charged year round.

We leave the Ecoflow in the car. We take the NUE unit into the field.

We had our first power outage yesterday.  Only lasted 15-20 minutes but it gave us the perfect opportunity to test the battery.  Worked perfectly!

The installation switches between solar panels and a gas generator to keep the battery charged year round.  It’s decreased my gasoline usage by 80% and improved the reliability of the system.
