Hybrid inverter doesn't display charging of battery

Hi everyone,
I wanna test my hybrid inverter ( MUST 5000W) i connect my batteris then my pannels ,but in the display screen doesn’t display the charging of batteries from solar,any connection between them.
thank you

Have you programmed the inverter correctly? Did you read through the manual and setup the configuration as required?

thank you for your reply
Normaly, to display that panels are charging batteries doesn’t need any programming?
it is not the same thing with MUST inverter?
befor,when i connect my Pannels with hybrid inverter display that the batteries are charging without any programm.
