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 “Cabling and Hook-up Configurations” on page 45 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.

Restrictions on Motor Size

An appliance may require three to six times its normal running current in

 

order to start. The Freedom SW 3000 can handle surges to 6000 watts for

 

ten seconds, which translates to a locked-rotor-amp rating of no more than

 

50 A. The locked rotor amp may be specified on the motor nameplate as

only.

“LRA” or “LRI”.

 

When considering appliances with large motors, follow these guidelines:

installers

•

Make sure that the motor’s LRA rating is no more than 50 A. The

 

 

Freedom SW 3000 may not be able to start a motor with a higher LRA,

 

 

and the Freedom SW 3000 will shut down if the attempt is made.

 

•

Make sure the battery bank, DC cables and DC fuses are capable of

qualified

 

handling up to 600 A DC for ten seconds. A weaker circuit may not be

 

 

 

able to provide sufficient power to the Freedom SW 3000 to allow the

 

 

Freedom SW 3000 to start up the appliance. Again if the circuit cannot

 

 

deliver the required current, the system may shut down or the fuse mayby

 

open.
