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 device. 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 disconnect and fuse 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.
Batteries
Every PROsine 2.0 system requires a deep-cycle battery or group
of batteries that provide the DC current that the inverter•charger converts to
AC. Different battery types and sizes are available; many of these are
discussed in Appendix C: “Batteries”. Automotive-type starting or “cranking”
batteries are not recommended, except for temporary emergency use. The
PROsine 2.0 Inverter•Charger uses 12-volt battery banks.
Ground Fault Circuit Interrupters (GFCIs)
A GFCI is a device that de-
energizes a circuit when a current to ground exceeds a specified value that is
less than that required to blow the circuit breaker. GFCIs are intended to
protect people from electric shocks and are usually required in wet or damp
locations.
Installations in marine and recreational vehicles may require GFCI protection
of branch circuits connected to the AC output of the inverter•charger. In
addition, electrical codes require GFCI protection of certain receptacles in
residential installations.
While the true sine wave output of the PROsine Inverter•Charger is equivalent
to the waveform provided by utilities, compliance with UL standards requires
that Xantrex test and recommend specific GFCIs. Xantrex has tested the
GFCI-protected 15A receptacles listed in Table 3 and found that they function
properly when connected to the AC output of the PROsine 2.0.
