suppression
The whole process of current closed-loop control and
complete avoidance of current impact has a perfect
over-current over-voltage suppression function.
Under voltage
suppression in
operation
Especially for users with low grid voltage and frequent grid voltage
fluctuations, even if it is below the allowed voltage range, the system
can maintain the maximum possible running time based on unique
algorithms and residual energy allocation strategies.
