Product Overview

Arcturus® is Firefly’s new range of secure integrated hybrid power generators (i-HPG). With both a diesel generator and hybrid energy storage contained within one secure unit, Arcturus® provides a simple all in one power solution ensuring drastically reduced fuel use and CO2 emissions. Delivered in a form factor that eliminates tampering and fuel theft vulnerability, Arcturus® also delivers class leading noise attributes with 0 dBA when in hybrid mode and just 65 dBA when the internal diesel generator is running.

The first to be released in the range is Arcturus® One, available with diesel generator sets ranging in size from 45-100 kVA all provided with an internal bunded 1000 litre sub-base fuel tank. In addition, inverter options range from 12-24 kVA and usable storage from 24-48kWh. Arcturus® One offers Firefly’s unique single phase and three phase switching as standard.

With a Tier IIIA compliant engine & hybrid storage, this generator delivers the lowest emissions of any rental specification generator on the market today and complies with all European regulations. Twin silencers and innovative sound attenuation techniques ensure Arcturus® is seen but never heard. Arcturus® One also boasts the latest OPzV battery technology providing 1,500 cycles at 80% D.o.D or enough for over 6 years of typical use.

Designed and built in the UK to ISO:9001 standards, Arcturus® One is straight-forward and easy to use, rated to IP65 and offers peace of mind for those concerned about fuel security, environment and noise.
