Limiting Charge Current (Multiple Inverters)
It is not advisable to set
Charger AC Limit
less than 12 Aac in a stacked system. The Power Save
function requires the master to activates the slave chargers in sequence only when the charge current
exceeds 11 Aac. If the setting is less than 12, Power Save will not activate any other chargers.
For more information on this function, see the Power Save section beginning on page 47.
In some systems, lower currents may be required due to battery bank size or other reasons. To achieve
lower currents, chargers can be individually set to
Off
so that the master inverter does not activate them.
For the location of the Charger Control command, see the menu tables beginning on page 76.
For more information on controlling the charger limits in a stacked system, see page 73.
Charge Cycle
The FXR inverter uses a “three-stage” battery charging process with Bulk, Absorption, and Float stages.
These stages follow a series of steps, which are shown on graphs and described beginning below. The
inverter’s factory default settings are intended for three-stage charging of lead-acid batteries.
Charging Graphs
Figure 6 shows the progression of steps of the three-stage charging cycle.
Figure 6 Charging Stages Over Time
Figure 7 shows the charge cycle used by the inverter when the
Float Time
menu item is set to
24/7
.
This setting eliminates the Silent and Refloat steps. The charger remains in Float continuously.
The Float stage lasts until the AC source is removed.
