Motor parameters self-detection

Without any limitation, the inverter can finish the motor parameter self-detection under static state, so as to achieve sound control effect.

Current / voltage limit

The current closed-loop control can completely avoid the current impact, and has the function of overvoltage limit.

Under voltage inhibition in running

It is especially suitable for the users with low network voltage and frequently fluctuated network voltage.  Even the voltage is lower than permissible voltage, and the system will maintain the longest possible running time according to the unique algorithm and residue energy allocation strategy.
