confi gurable settings are available from each menu.
3.3.1

AC IN Menu

Use this menu as a quick means of changing your AC I N setting to coordinate
with the circuit breaker rating from the incoming AC source.
• AC IN – This selection ensures the inverter's AC loads receive the
maximum current available from the utility or your generator power.
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 I N setting, the current that was used for charging the
batteries will automatically be reduced. This ensures the AC loads have all
the available current when needed. The feature is not available on MM and
MMS Series inverter/chargers.
Default setting: AC I N = 30 Am ps
Range: 5 Am ps, 15 Am ps, 30 Am ps, 50 Am ps
Where to set: Adjust the AC I N 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. If
the breaker on the AC source is tripping (because it is a weak breaker), try
reducing this setting to the next lower level.
N ot e : I f t he ME- MR is connect ed t o a dual source invert er ( i.e.,
MSH4024RE) ,t he AC I N set t ing applies t o bot h input s ( AC1 and AC2) .
CAUTION: The AC I N setting does not limit the current to the
inverter loads. If the current to 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 of this breaker.
