5.3. GFDI Fault
Before the inverter starts to connect to the grid, the inverter will first detect the impedance of PV + to
ground, and the impedance of PV – to ground. If any of these impedance values is less than 33 k, the
inverter will not connect to the grid and will report an error F24 on its LCD.
6. Maintenance of the System
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.
