2. You may have a faulty PV panel
(earth short)
3. Restart inverter
F24
DC insulation impedance 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 connected to the ground.
F26
The bus bar is unbalanced
1. Please wait 5 minutes to see if it
returns to normal.
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 specification
2. You may need to adjust the
frequency on the grid set up page.
F56
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 batteries
