Error Code Description Solutions
F24
DC insulation im-
pedance failure
PV isolation resistance is too low
1.Check if the connection of PV panels and inverter are firmly con -
nected.
2.Check if the earth bond cable on inverters is connected to the
ground.
F26
The bus bar is un-
balanced
1.Please wait 5 minutes to see if it returns to normal.
2. Fully reset the inverter.
F35 No at: grid
Grid voltage fault
1.Check if the voltage is in the range of standard voltage in specifica
-
tion this can be adjusted via the grid set up page.
2.Check if grid cables are correctly connected.
F42 AC line low voltage
Grid voltage fault
1.Check if the voltage is in the range of standard voltage in specifica
-
tion this can be adjusted via the grid set up page.
2.Check if grid cables are correctly connected.
F47 AC over frequency
Grid frequency out of range
1.Check if the frequency is in the range of specification
2.You may need to adjust the frequency on the grid set up page.
F48
DC bus bar voltage
is too low
Battery low voltage
1. Check if the battery voltage is too low.
2. If the battery voltage is too low use the PV or grid to charge the
battery.
3. Check the battery BMS
Important: Especially with Lithium batteries, ensure that the bat-
teries Max. discharge current or power specification is the same or
higher than the inverter specification.
F64
Heat sink high-tem-
perature failure
Heat Sink temp is too high
1.Check if the working environment temperature is too high.
2.Turn off the inverter for 30 minutes and restart.
