6.3. GDFI Fault
Before the inverter connects to the Grid, it will detect the impedance (effective resistance) of the
solar PV + to Ground, and the impedance of the solar PV - to ground. If any of the impedance
values are less than 33kΩ, the inverter will not connect to the Grid and will report an error F24
on its LCD.
7. MAINTENANCE
The inverter is low maintenance. However, it is important that at least twice a year (for dusty
environments this may need to be carried out weekly) all the cooling fans, air ducts are cleaned
and dust free.
Check if there are no fault codes and Lithium battery communication is correct.
Weekly cleaning statement: Suggest micromesh filters as an available option, micro ants here
are a real problem.
