⑥⑦
30mA RCD (Comply with local regulation)
Note 1: * If the battery is integrated with a readily accessible internal DC breaker, no ad-
ditional DC breaker is required.
Note 2: The values in the table are recommended values and can be set to other values
according to actual conditions.
Note 3: The rated current of breaker ② is suggested to lower than that of breaker ⑤.
Note 4: If the rated current of on-site power cables are lower than those recommended
above, the breakers specification should be considered to match the power cables in
first priority.
Note 5: The AC port takes power from the grid and is set according to the grid circuit
breaker.
