DC and AC Temperature High
I have a sunsynk 5kw inverter and i have noticed there are two temperature readings. AC Temperature and DC Temperature. I have seen that constantly the DC temperature exceeds 60 degrees Celsius even goes as high as 70 degrees though AC Temperature does the same the increases are not as high. Is this not potential problem for the inverter given the operational temperature range on the inverter data sheet is up to 60 degrees Celsius.

60C is maximum ambient temperature at which components inside will still be at acceptable temperature.
60-70C is actually quite cold for power electronics (usually rated for at least 125C)
