Back-up output
The hybrid ET series inverter can handle backup output congestion for a certain amount of time. For more
details, see the technical parameters of the inverter (Chapter 4.3) The inverter also has protection against
exceeding its maximum temperature
Allowed appliances connected to the Back-Up output:
• Inductive appliances: 1.5P climate control without frequency changer. Connecting two or more of these
air-conditioning units can cause back-up output instability.
• Capacitive appliances: Total power <= 0.6 x rated power of the model.
• Note: Do not connect a 3-phase inductive load (engine) without zero conductor (no appliances allowed
that have a high shock current at startup)
• To plug in complex devices, consult GoodWe technical support.
Note:
For convenient maintenance, install a 3-phase switch on the Backup outlet and mains. By switching, you can
conveniently power the BackUp output during inverter maintenance (see the picture below)
Back-Up output overload protection:
The inverter restarts during overload and during repeated overloads the restart time after restart is extended
and during repeated overloads, the inverter restart time can be extended up to one hour. To reset the overload
follow these steps:
•
Reduce the connected power that is on the Back-Up output
•
In the PV Master app, in "Advanced Setting" click on "Reset Back-Up Overload History"
