4.3.8.3 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 certain time(T recovery).
