5. Error Code and Service
Recovery method explanation:
I. Recovery method A: Auto-restart after default reconnecting time.
II. Recovery method B: Auto-restart after waiting 10 sec.
III. Recovery method C: Auto-restart after waiting 10 sec. But enter recovery method D when
error four times (show d-XX error code.)
IV. Recovery method D: Turn on solar power conditioner by hand after repaired.
Error code
F-00
Recovery method : A
Description Utility voltage over setting parameter
Protection level Over 255V(default value) [Parametr:250V / 255V / 260V]
Activation time 1 sec(default value) [Parametr:1S / 1.4S / 1.8S]
Cause Voltage of the utility grid rises due to the electric supply status of the power
company.
Check
Measure the receiving voltage at the output terminal of the solar power
conditioner. If L-N is 255V (in case of preset value) or more, it is in abnormal
condition.
Case.1
Action Change the parameter setting to a higher level, and make sure the utility
voltage is low enough than setting value.
Cause Output impedance is too large to make the output terminal voltage is over
setting value.
Check Check the impedance between inverter and the grid, and the cable loss can
not be over 1% of full power.
Case.2
Action Make the impedance as short as you can.
Cause Grid voltage detector circuit is failed.
Check Check the voltage of receiving utility voltage, if its voltage is large than 210
and fuse is fine, some problem is inside the solar conditioner.
Case.3
Action Replace a new solar power conditioner.
Error code
F-01
Recovery method : A
Contents Utility voltage under setting parameter
Protection level
Less 210V(default value) [Parametr:205V / 210V / 215V]
Activation time
1 sec(default value) [Parametr:1S / 1.4S / 1.8S]
Case.1 Cause Power failure of the utility grid.
