Load Management
Incoming AC power is shared between the AC loads and the charger. The AC loads are given priority; this means
that the charger will reduce its output when AC loads are applied. This feature also controls the total amperage draw
of the system so that the utility service circuit breaker is not tripped. The load management feature will return the
charger to full output when the AC loads are removed or reduced.
The total amperage draw of the system is controlled by the AC limit setting also known as the BCR. These terms
may be used interchangeably. The default AC limit is set by the factory to 15 A. The BCR may be changed at the
factory or through the NVM Setup Utility, 7 Seg Display, or the optional LCD remote.
NOTE: Dynamic external loads (such as motors or pumps that continuously vary the power required) may cause
variations in the charge rate. The charger may reset if the dynamic load causes the input AC waveform to become
temporarily disqualified.
