Ems Status Leds - Redback SH5000 Owner's Manual

EMS Status LEDs

The EMS controls the inverter functionality, and all internal and external
communications. The EMS a.k.a. Control Board is located inside the Balance of
System (BoS). The EMS Status LEDs are visible in the BoS Switchgear Hatch.
The table below lists EMS LED indications, probable causes, and rectification
steps you can try yourself. Refer to page 9 to identify controls.
If the problem is not solved contact your installer for assistance.
A note about EMS Labels
In 2018, the EMS LED labels were updated: the unused 4G LED was repurposed for Bluetooth notification, and the Wi-Fi LED
was renamed to Network. There were no other changes to the EMS.
In this document "Network LED" means the Network LED or the Wi-Fi LED, and "Bluetooth LED" means the Bluetooth LED or
the 4G LED. Your inverter and software work the same regardless of the labels.
