13A Grid (AC1) Amps AC
This is the maximum amount of current that can be drawn from the grid
(AC1 input) by the loads and battery charger combined. This settings
determines the amperage level at which point the inverter starts drawing
power from the batteries to add to the utility power to meet the demand of
the loads. This is the AC load support feature.
If the loads exceed this setting, the inverter will draw from the batteries
and add it to the utility power to meet the demand of the loads.
Typically, this value is set to the size of the AC circuit breakers feeding
the inverter's AC input.
13B Gen (AC2) Amps AC
This is the maximum amount of current that can be drawn from the
generator (AC2 input) by the loads. This settings determines the
amperage level at which point the inverter starts drawing power from the
batteries to add to the generator power to meet the demand of the loads.
This is the AC load support feature.
If the loads exceed this setting, the inverter will draw from the batteries
and add it to the generator power to meet the demand of the loads.
Typically, this value is set to the size of the generator's AC circuit breaker
feeding the inverter's input or the maximum output amperage capacity of
the generator.
This setting is very dependent on the performance of the generator. Other
factors such as altitude, line losses between the generator and the inverter
will require lowering this setting to below what the generator is rated for.
For best results, begin with a setting half your expected generator current
capacity and gradually increase this setting while verifying the AC
voltage on the AC2 inverter terminals stays at lease several volts above
the 13D Input Lower Limit VAC setting.
