Notes
All protection is automatically
recovered.
To protect the battery, if the
unit needs to be restarted after
low voltage protection, the
voltage of DC input should be
above 12V.
To extend the life of the fan it
will stop when there is no load.
The speed of the fan increases
as the load increases.
The unit is completely insulat-
ed in input and output for
added safety.
For each piece of equipment you will be operat-
ing from the inverter you must determine the
battery’s capacity (how long the battery can
deliver a specific amount of current—in automo-
tive batteries, usually 25 amperes). For example, a
battery with a reserve capacity of 180 minutes
can deliver 25 amperes for 180 minutes before it
is completely discharged.
Calculate the total watt-hours of energy con-
sumption (power x operating time). To determine
how many 12 volt ampere hours will be con-
sumed divide the watt hours by ten.
