Connect the Inputs:
There are a number of means available to charge the unit. Instruc ons on how to connect charging inputs (e.g. solar PV,
wind turbines, Kinectrics equipment) are available as appendices to this manual or included with those products at the
point of purchase. All user manuals can also be downloaded from the manufacturer’s website at www.fireflysolar.net
It is also possible to operate the unit only using the internal ba ery bank, without external inputs connected.
When Cygnus is connected to an external AC supply, the output voltage is transferred from its input.
In this case the unit will not modify the AC output: Consumers will be supplied with an output
iden cal to the source.
