Why X1-SPT series need the load EPS overload reset?

Because X1-SPT series inverter without LED control screen, when EPS overload occurs, SPT inverter will stop output. What need to do is to turn off some low level EPS loads which make the EPS loads less than the EPS rated power. At the same time please clear the EPS overload alarm and reset the system. But the local way currently need the APP in smart phone. For some end user who are not good at using the smart phone or there is no WiFi for remote reset, it’s not a friendly way, as a result, Solax developed an external local reset solution.
