NOTE: DEFAULT FREQ parameter is xed al 60Hz for EVO-1212F / 1212F-HW and EVO-1224F / 1224F-HW (Option
0=60Hz). If option 1 is entered for these models, the screen line will show "! 1=xxHz" meaning that Option 1
is invalid.
4.5.2.2 GRID MAX CURRENT (Table 4.6, Parameter Setup Screen No. 2)
In Charging Mode, the net AC input current from the Grid is the sum of the AC side charging current and the pass
through load current. Based on the rated capacity of the Grid Branch Circuit, the net AC input current will be required
to be limited to prevent overloading of the Grid Branch Circuit.
EVO™ Series has a very powerful battery charger that will require a proportionate higher AC input current from the
Grid. The Grid Branch Circuit will also be required to provide current to the AC loads. The desired maximum value
of input current from Grid can be programmed (Default setting is 20A for Models EVO-1212F / 1212F-HW / 1224F /
1224F-HW and 30A for Models EVO-2212 / 3012 / 2224 / 4024). The EVO™ will automatically reduce charging current
to support the AC loads on priority and use whatever is extra for charging. This will prevent overloading of the Grid
Branch Circuit.
If the net AC input current is 1A more than the value of parameter GRID MAX CURRENT for 1 sec, the AC side charging
current is clawed back to ensure that GRID MAX CURRENT value is not exceeded. If the value of pass through load
current increases to a value of 1A more than the programmed value of GRID MAX CURRENT for 5 sec, input over
current protection will be activated based on option to either transfer to Inverting Mode or to shut down the EVO (Refer
to details of these 2 options under parameter INPUT OC PROTECT at Section 4.5.2.11):
