Planning Preparations
This guide for use by qualified installers only.
For dual input, the wire may be red or black; consult the
documentation provided with the AC source (utility or
generator).
Size of AC Output Wiring
Wire size must be coordinated
with the current the wiring will carry. This current may be
determined by the 15-amp (Freedom SW 3524-230) and 11-
amp (Freedom SW 2524-230) maximum inverter current, or
by the bypass current, which is determined by the overcurrent
protection provided ahead of the Freedom SW 230V.
Size of Wiring Downstream of the AC Output Breaker
The wiring used between the AC output breaker and your
loads must be sized in accordance with the rating of the
output breaker.
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 57 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 62.
For detailed information about specific brands of batteries,
consult individual battery manufacturers.
