What should I do, if my EVC comes up with the fault "emstop_fault"?

Under Eco mode it is charging and discharging now and then, it may cause this issue, but this issue will not happen under fast mode， Generally speaking, this issue will auto recover.
If can not recover automatically, please follow the steps below to troubleshoot:
1. Switch on the red button on EVC side
2. Reboot the EVC
3. Contact solax support to update the firmware of the EVC
