DC Components

Batteries

The Freedom SW 3000 system requires a 12 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 41 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 “Cabling and Hook-up Configurations” on page 45.

For detailed information about specific brands of batteries, you’ll need to consult individual battery manufacturers for this information.

DC Disconnects and Over-Current Devices

The DC circuit from the battery to the inverter/charger must be equipped with a disconnect and over-current protection device. (Refer to your applicable installation code.)

Type This device usually consists of a circuit breaker, a “fused- disconnect,” or a separate fuse and DC disconnect. Do not confuse AC circuit breakers with DC circuit breakers. They are not interchangeable.

Rating The rating of the fuse or breaker must be matched to the size of cables used in accordance with the applicable installation codes.

Planning

Location The breaker or fuse and disconnect should be located as close as possible to the battery in the positive cable. Applicable codes may limit how far the protection can be from the battery.
