WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal and
the ring terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply antioxidant substance on the terminals before terminals
are connected tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/ dis-
connector, be sure po) must be connected to po) and negative(-)
must be connected to negative(-).
AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and
AC input power source. This will ensure inverter can be disconnected safely during maintenance and fully protected
from over current of AC input.
Suggestion AC breaker: 50A for 1KW-3KW, 80A for 4KW-6KW.
CAUTION!! Please don't connect the output wring to "Grid" terminal or connect the grid wring to the "Load" terminal.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! It's very important to use appropriate cable for Grid connection for system safety and efficient operation.
To reduce injury risk, please use the proper suggested cable size as below.
