DC Components
Batteries
The RS2000 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.
For general information about batteries, see “Battery Information” on page 39.
For detailed information about specific brands of batteries, you’ll need to consult
individual battery manufacturers for this information.
DC Disconnects and Over-Current Device
The DC circuit from the battery to the inverter/charger must be equipped with a
disconnect and over-current device. (Refer to your applicable installation code.)
This 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. The rating of the fuse or breaker must be matched
to the size of cables used in accordance with the applicable installation codes. 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.
DC Cabling
DC cabling includes all of the cables and connectors between the batteries, the DC
disconnect and over-current protection device, and the inverter/charger. All
installations require multi-strand insulated cables as well as disconnect and over-
current devices. DC cable sizes are indicated by AWG notation. Under the AWG
standard, a larger gauge number indicates a smaller size diameter. Wire size is
usually marked on the cables for sizes this large.
See Table 2 for required DC cable size and required fuse size for the RS2000. The
DC cables must be copper and must be rated 90 °C minimum.
Important:
Avoid excessive cable lengths to ensure optimum system
performance.
