3.0 Setup
03 Charger Setup
03A AC Input Amps:
This selection ensures that the combined current
draw from the charger and the AC loads does not exceed the maximum
input current that is available. Whenever the utility or generator is
connected to the inverter, the current used to power the AC loads and
to charge the batteries is monitored. When the total current used to
power the AC loads and charge the batteries begins to approach the
AC Input Amps
setting, the current used for charging the batteries is
automatically reduced. This ensures the AC loads have all the available
current when needed.
Default setting
-
Amps = 30 Amps
Where should I set AC Input Amps?
Set the
AC Input Amps
setting
to match the current rating of the utility power or the generator’s circuit
breaker. If using multiple AC sources (utility and generator) through an
AC transfer switch, adjust this setting to the smaller AC breaker size. This
setting is dependent on the stability of the AC source. If using a generator,
factors such as altitude and output voltage regulation may require a lower
setting than the generator’s breaker size. For best performance, lower this
setting to 1/3 its rated capacity and gradually increase it while ensuring the
voltage level stays above the
03D VAC Dropout
setting.
CAUTION:
The
AC Input Amps
setting does not limit the current
to the inverter loads. If the current from the loads on the output
of the inverter are greater than the circuit breaker rating on the
incoming AC source, you may experience nuisance tripping on
this breaker.
Info:
This setting controls the input current differently
depending on the inverter/charger model and the AC input wiring
con
fi
guration selected for your particular model. ME, MS and
RD Series models have 2 AC inputs (HOT IN 1 and HOT IN 2).
AC Input Amps
is only monitored on HOT IN 1 on these models
when wired as a dual-in/dual-out con
fi
guration. On these models,
if a single-in/single-out con
fi
guration is selected and HOT IN 1
and HOT IN 2 are jumped together, then set the
AC Input Amps
setting to 1/2 the input breaker size as 1/2 the current will pass
through HOT IN 1 and HOT IN 2 simultaneously.
If MS-AE or MS-PAE models are used, these models have HOT IN
1 and HOT IN 2 and the current on
both
inputs are monitored.
Set
AC Input Amps
to match the input breaker size on these
models.
03B Battery Type:
Used to select the battery type, which determines
the battery charge pro
fi
le and ensures the batteries are receiving the
proper charge voltage. The
fi
xed voltage selections are
GEL
(for Gel
batteries),
Flooded
(for liquid lead acid batteries),
AGM 1
(for Lifeline
AGM batteries), and
AGM 2
(for East Penn/Deka/Discover/Trojan
AGM batteries).
The
Custom
selection allows the Float, Absorb and
Equalization charge voltage settings to be individually adjusted. S
ee
Table 3-1 to determine the speci
fi
c charge voltage based on the battery
type selected.
Default setting
-
Battery Type = Flooded
