2) If using a parallel configuration, check if all battery cables have the same length. As the batteries are low
voltage compared to the mains, the current is high, so check the cable size and notice if they have the
same length.
3) Check the C rating of the battery.
4) Check the maximum current discharge setting of the inverter.
5) Check the maximum power setting (Max sell Power) of the inverter.
F63 - ARC fault
This error is caused by a faulty connection on the solar panel, which causes noise.
This problem is actually a loose connection of the solar panels, and when something is causing noise on
the solar cable. You can switch off the system, but it is better to locate the problem since there is a potential
fire hazard.
For this type of fault, you really need to go and check every single solar panel, every single connection,
since this fault can appear from nowhere. The system can normally be working, and then suddenly, in the
middle of the day, this can happen.
F64 - Heat sink high-temperature failure
This error is displayed due to an over-temperature of the IGBT, possibly caused by a blocked fan or
ventilation.
If this fault occurs and the problem is not solved rapidly, it can damage the inverter.
1) Switch off the inverter and allowed to cool down
2) Clean all ventilation
