Freedom SW 230V Installation Guide
Battery Information
Battery Banks
As your power requirements increase, you may need to use
more than one battery to obtain sufficient capacity. Batteries
can be connected in parallel, in series, or in series-parallel to
create higher capacity systems.
See “Battery Cabling and Hook-up Configurations” on page
62 for more information about battery inter-connection
schemes.
Mixing Batteries
Batteries connected in parallel should be
of the same type and amp-hour rating and from the same
manufacturer.
It is not recommended to connect batteries of different types,
amp-hour ratings or manufacturers. Improper charging and
decreased battery life will result.
Battery Bank Sizing Worksheet
The following worksheet is a guide to help you determine
your battery needs. Be generous in estimating the time for
which you will run each of the loads to ensure sufficient
battery capacity.
Restrictions on Motor Size
An appliance may require three to six times its normal
running current in order to start. The Freedom SW 3524-230
can handle surges to 6800 watts for five seconds, which
translates to a locked-rotor-amp rating of no more than
50 amps. The locked rotor amp may be specified on the motor
nameplate as “LRA” or “LRI”.
When considering appliances with large motors, follow these
guidelines:
•
Make sure that the motor’s LRA rating is no more than 50
amps. The Freedom SW 230V may not be able to start a
motor with a higher LRA, and the Freedom SW 230V
will shut down if the attempt is made.
•
Make sure the battery bank, DC cables and DC fuses are
capable of handling up to 600 amps DC for five seconds.
A weaker circuit may not be able to provide sufficient
power to the Freedom SW 230V to allow the Freedom
SW 230V to start up the appliance. Again, if the circuit
cannot deliver the required current, the system may shut
down or the fuse may open.
