Product Series >Counter-current protector

Product features
There is always different voltage in series return current branch.If the bug or shadow and so on takes place in some branch to make low voltage,the current from high voltage branch will be flowed to low voltage return circuit branch.As to off gird system,when the modules of matrix do not generate power,the current of battery will be flowed to the return circuit.This is the counter current.To solve this question,it is necessary to mount counter current protector in each series return circuit branch.
