ii. Then, the phase of the Inverter voltage relative to the phase of the Grid / Inverter Generator
voltage is tracked by 1º per cycle. When the phase of the Inverter voltage is within ± 3.5º of
the input voltage waveform, the Transfer Relay is activated to transfer the AC load from the
Grid / Inverter Generator to the Inverter Section at zero crossing of the voltage waveform.

4.5.2.11 INPUT OC PROTECT
(Table 4.6: (i) Parameter Setup Screen No.8 under Column 1 for EVO-1212F/1212F-HW/1224F/1224F-HW

If the net AC input current is 1A more than the value of GRID MAX CURRENT (See Section 4.5.2.2) or GEN MAX
CURRENT (See Section 4.5.2.3) for 1 sec, the AC side charging current is clawed back to ensure that GRID MAX
CURRENT / GEN 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 / GEN MAX CURRENT for 5 sec, input over current
protection will be activated based on the following 2 options provided through parameter INPUT OC PROTECT:
a) Option "0=INV mode" (Default Option). Set up screen is shown below:

o If the AC input current is 1A more than the programmed value of GRID MAX CURRENT / GEN MAX
CURRENT for more than 5 sec, the unit will switch over to Inverter Mode to ensure that AC power to
the load is maintained.
o If the load reduces to 1A less than the programmed value of GRID MAX CURRENT / GEN MAX
CURRENT for 5 sec, switch back to Charging Mode
b) Option "1=Shutdown" (Default Option). Set up screen is shown below:

o If the AC input current is 1A more than the programmed value of GRID MAX CURRENT / GEN MAX
CURRENT for more than 5 sec, Fault Mode will be activated:
• There will be no AC output because the Transfer Relay will be de-energized, charging will be stopped
and PWM drive to the Inverter Section will be switched off
