100A MPPT solar charge controller with terminal block and copper tracks INSUFFICIENT for 40 Amper...
This time I have to criticize a product, advising against using it for currents above 40 A, even though it's advertised as having a maximum current of 100 A. The same product is also sold for nominal currents below 100 A, such as 40/50/60 A, but the terminals are still inadequate and the cooling is very poor.
