Battery Connection

CAUTION: For safety operation and regulation compliance, it's requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be requested to have a disconnect
device in some applications. However, it's still requested to have over-current protection (typical 120A)
installed.
WARNING! All wiring connection must be performed by a qualified personnel.
Please follow below steps to implement battery connection:
1. This inverter supports 24VDC system. Connect all battery packs as below chart. It's suggested to connect
at least 100Ah capacity battery.
2. Plug battery cable into the battery connectors of the unit. Make sure polarity at both the battery and the
inverter/charge is correctly connected.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!!
positive (+) must be connected to positive (+) 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 the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 40A.
WARNING!! When using sockets as the output, please make sure that the current of each socket is less than
10A, in case of electric hazard.
WARNING! All wiring must be performed by qualified person.
Before making the final DC connection or closing DC breaker/disconnector, be sure
