This parameter defines the frequency converter action type under the condition of low
frequency protection, dry pumping protection, overcurrent protection and minimum power
protection.
0: Warning, automatic recovery.

Overcurrent protection function:
Under the photovoltaic mode, when the output current of
the inverter is less than F12.25 and remains for F12.26 times, the inverter will enter into the state
of draining protection, the operating frequency will be reduced to 0.00Hz, and A-43 warning will
be displayed. After the system is in the protection state of pumping out and maintained for F12.27
times, it exits the overcurrent protection state and starts running again.
F12.25=0 or F12.26=0, this function is invalid.

When the photovoltaic inverter is in operation, function terminal No. 70 is effective, and after
maintaining F12.28 times, it enters the full-water standby state, and the keyboard display warns
"A-46";
under the full-water standby state,when the function terminal No. 70 is invalid, and the
function terminal No. 71 is valid and remains longer than F12.29 times, the inverter will resume
operation automatically
When F12.28=0, this function is invalid.
