DC Components

Batteries

The Freedom SW 230V system requires a 24-volt, lead-acid deep- cycle battery or group of batteries to provide the DC current that the inverter/charger converts to AC power. The battery may be a flooded, gel, or AGM type.

See “Battery Information” on page 52 for information on:

•Estimating the battery size that will meet your requirements.

•Designing battery banks.

•Restrictions on the size of appliances.

For information on cabling and hooking up batteries, see “Battery Cabling and Hook-up Configurations” on page 57.

For detailed information about specific brands of batteries, consult individual battery manufacturers.

DC Cabling

Definition DC cabling includes all of the cables and connectors between the batteries, the DC disconnect and overcurrent protection device, and the inverter/charger.

Type All installations require multi-strand insulated cables. The DC cables must be copper and must be rated 75°C minimum. In Australia, they must be rated 90°C minimum.
