PV input terminal installation
Plug in PV terminal
Notes:
- P l e a s e m a k e s u r e t h e P V i n p u t voltage/current not beyond the specification before plug in.
- When installing the PV terminal, pay attention to the distinction between the positive and negative terminals and the one-t o – o n e c o r r e s p o n d e n c e b e t w e e n t h e terminals and hybrid inverter.
- When the terminal is docked, there is a click sound. After the terminal is docked, gently pull the PV cable to observe whether the terminal is shaking or not.
Battery power line connection
