Error Code Description Solutions
F13 Working Mode Change
Inverter work mode changed
1. Reset the inverter.
2. Seek help from Sunsynk.
F18
AC over current fault or
hardware
AC Slide over current fault.
1. Check if the backup load power is within the
range of the inverter.
2. Restart, and check if it is normal.
F20
DC over current fault of
the hardware
DC Over current fault
1. Check if PV module and battery connections.
2. Reset the system.
F23
AC leakage current is
trans over current
Leakage current fault
1. Check the PV module and inverter cables.
2. You may have a faulty PV panel (earth short)
3. Restart inverter
F24
DC insulation imped-
ance failure
PV isolation resistance is too low
1. Check if the connection of PV panels and inverter
are firmly connected.
2. Check if the earth bond cable on inverters is con-
nected to the ground.
F26
The bus bar is unbal-
anced
1. Please wait 5 minutes to see if it returns to nor-
mal.
2. Fully reset the inverter.
F35 No at: grid
1. Check if the inverter’s connected to the AC grid.
2. Check if the RSCD had not tripped.
3. Check if the switch and fuses between the inverter
and grid are all switched on.
F42 AC line low voltage
Grid voltage fault
1. Check if the voltage is in the range of standard
voltage in specification this can be adjusted via
the grid set up page.
2. Check if grid cables are correctly connected.
F47 AC over frequency
Grid voltage fault
1. Check if the voltage is in the range of standard
voltage in specification this can be adjusted via
the grid set up page.
2. Check if grid cables are correctly connected.
F48 AC lower frequency
Grid frequency out of range
1. Check if the frequency is in the range of specifica-
tion
2. You may need to adjust the frequency on the grid
set up page.
