Wattsonic AIO ESS | USER MANUAL

Danger: Do not connect the N-wire as a protective ground wire to the inverter casing. 
Otherwise, it may cause electric shock.

Attention: Good grounding is good for resisting surge voltage shock and improving 
EMI performance. Inverters must be well-grounded.
For a system with only one inverter, just ground the PE cable.
For a multi-inverter system, all inverters PE wire need to be connected to the same 
grounding copper bar to ensure equipotential bonding.

Single inverter wiring diagram

This diagram is an example without special 
requirement on electrical wiring connection. 
Neutral line of AC supply can be isolated or 
switched.

This diagram is an example for Australia and 
New Zealand. Neutral line of AC supply must 
not be isolated or switched.

Ground terminal connection steps:

1) The external grounding terminal is 
located in the lower right side of the 
inverter.
2) Fix the grounding terminal to the PE wire 
with a proper tool and lock the grounding 
terminal to the grounding hole in the lower 
right side of the inverter.

External ground connection

Connect the inverter and ground 
bar through PE wire to achieve the 
purpose of grounding protection. 
Please always remember wiring the 
PE wire before wiring other wires.
