California-based power solutions firm Polar Power has received an order from a major US wireless carrier for 57 of its 15 kW backup DC gensets.

The units will be shipped over the next two weeks to provide emergency power for hurricane-hit telecom sites in Puerto Rico.

According to the US Federal Communications Commission, 90 per cent of Puerto Rico’s cellular towers are out of service after Hurricane Maria devastated the island, as is around 75 per cent of fibre-optic coverage and 40 per cent of the wired network.

Polar Power CEO Arthur Sams said the order “comes at a time when over 3.5 million US citizens are without some form of access to cellular phone or data to communicate with family and friends”.

Polar Power says its DC gensets (pictured) are well-suited for telecom site backup power due to their small footprint, lighter weight than AC generators, ability to operate with low natural gas pressure, multiple fuel capacity, low noise and low cost.

“We look forward to continuing our collaboration with all of our Tier-1 wireless carrier customers as we work together to provide solutions to aid in the redevelopment of Puerto Rico’s wireless networks,” Sams said.
