5.2.8.3. P(V)
When grid voltage rises up to a lock-in voltage(V lock-in) and inverter’s
present output power is greater than lock-in power(P lock-in), inverter
will reduce the output power and keep it at a certain value(P lock-out)
until grid voltage drop back to lock-out voltage(V lock-out) and passing
a certen time(T revcovery).
