Input Support
A system display is required to control this function. When this function is enabled, the inverter limits
the current draw from an AC source, augmenting it with additional current from the batteries when
necessary. This helps prevent overloading a small AC circuit or generator during short-term use.
the current draw from an AC source, augmenting it with additional current from the batteries when
necessary. This helps prevent overloading a small AC circuit or generator during short-term use.
Initially the AC source current is used for both loads and battery charging. In the MATE system display,
the ac1/grid limit or ac2/gen limit settings control the maximum AC draw. In the MATE3 system
display, these settings are made by the Grid Input AC Limit and Gen Input AC Limit menu items. If the
AC draw exceeds the setting, the inverter reduces its charge rate to give priority to the loads.
the ac1/grid limit or ac2/gen limit settings control the maximum AC draw. In the MATE3 system
display, these settings are made by the Grid Input AC Limit and Gen Input AC Limit menu items. If the
AC draw exceeds the setting, the inverter reduces its charge rate to give priority to the loads.
¾ The charge rate will be reduced as much as necessary to support the loads. If the loads equal the amperage
setting, the charge rate will be zero.
¾ If the AC loads exceed the amperage setting, the charger will begin operating in reverse. It will take power
from the batteries and use it to support the incoming AC current.
IMPORTANT:
If the AC loads exceed the amperage limit setting, the inverter will drain the batteries. If
the loads are sustained, the batteries may discharge to the point of Low Battery Cut-Out
and the inverter may shut down with a Low Battery error. (See pages 13 and 37.) To
prevent the loss of backup power, load use should be planned accordingly.

In the MATE system display, this feature is activated by the ac2/gen support menu item, located in the
ADVANCED menus. In the MATE3 system display, it is activated by the Input Support menu item,

¾ Although the menu is titled “ac2/gen support” in the MATE, it functions equally well whether the AC source
is a generator or the utility grid.
¾ Choose between generator or grid criteria using the MATE’s ac transfer control menu. The default is grid.
The <GRID> and <GEN> soft keys will toggle between these respective options.
¾ The default selection is on. It can be switched off using the <OFF> soft key. The MATE’s ac transfer control
menu must be selected to gen in order to do this. In current models, if ac transfer control is set to grid, the
support feature cannot be disabled.
