SAFETY WARNING
Any installation and operation on BESS must be performed by qualified electricians, in compliance with standards,
wiring rules or requirements of local grid authorities or companies (like AS 4777 andAS/ NZS 3000 inAustralia).
Before any wiring connection or electrical operation on BESS, all battery and AC power must be disconnected from
BESS for at least 5 minutes to make sure BESS is totally isolated to avoid electric shock.
The temperature of BESS surface might exceed 60°C during working, so please make sure it is cooled down before
touching it, and make sure the BESS is untouchable for children.
Usage and operation of the BESS must follow instructions in this user manual, otherwise the protection design might
be useless and warranty for the BESS will be invalid.
Do not open BESS cover or change any component without SEMOOKii authorization, otherwise the warranty
commitment for the BESS will be invalid.
Appropriate methods must be adopted to protect BESS from static damage. Any damage caused by static is not
warranted by SEMOOKii.
The neutral continuity is NOT maintained internally, it must be achieved by external connection arrangements like in
the system connection diagram for Australia on page 31 section 2.3.3.
This BESS includes an integrated residual current device (RCD).
If an external residual current device (RCD) is used, a device of type A should be used, with a tripping current of 30
mA or higher.
This BESS uses active anti-islanding protection, the method is shifting the frequencyof the inverter away from nominal
conditions in the absence of a reference frequency (frequency shift).
This BESS is a multiple mode inverter, it is used for outdoor unconditioned without solar effects. The maximum
operating ambient temperature is 55°C.
Product should not be used in multiple phase combinations.
