Screw the cap on and plug onto inverter side.
Note: There will be a click sound if connectors are inset correctly into BAT plugs.
Note: For the compatible lithium batteries (Pylon/BYD) connection, please refer to battery
connection.
2.4.3 On-Grid&Back-up Connection
An external AC breaker is needed for on-grid connection to isolate the inverter from the utility
grid when necessary.
The requirements for the on-grid AC breaker are shown below.
Note: The absence of AC breaker will lead to inverter damage if an electrical short circuit happens on
grid side.
1. Use separate AC breakers for individual
inverters.

2. On the AC side, an individual breaker
should be connected between the inverter
and grid but before any loads.
