Sunway NT 10000 - Manual (Page 63)

147
Error
Error 016
Grid under-
voltage 3-phase
Errors 017 to 019
AFI fault current
Causes
The grid voltage is too low.
The Solar Inverter monitors
the lower and upper admis-
sible grid voltage limits in
3-phases. If the voltage
drops below the lower limit
(U
min
= 184 V), the Solar
Inverter will automatically
switch off and will only
restart when the voltage
value rises above the lower
limit again. The shutdown
can already be triggered if
the voltage drops below the
lower limit for a short time.
The AFI fault is flagged if
fault current has penetrated
the PV system and the Solar
Inverter has subsequently
disconnected from the grid.
Remedies
Ask your power supply company about
the stability and design of the grid.
The entire PV system must be checked
for insulation faults.
