10 Freedom SW 2000 Installation Guide
Planning the Installation
DC Components
Batteries
The Freedom SW 2000 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 37 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 41.
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.
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.
