Firmware version 1.33 for SmartSolar MPPT RS controllers introduces direct error reporting for PV isolation failures to GX devices and the VRM portal. When system isolation resistance drops below the specified threshold, the platform generates automated alarms to alert operators of electrical faults.
This enhancement expands remote diagnostic capabilities beyond local app connections, facilitating faster responses to temporary moisture issues or structural cable damage. The update serves strictly as a monitoring tool and does not substitute for regular physical inspections by qualified technicians.
