Wiring AC Output
warning
You must install a separate single-phase circuit-breaker or other load
disconnection unit for each inverter in order to ensure that the inverter can
be safely disconnected under load.
NOTE:
The inveter have the residual current detect and protect function, if you
have device the AC breaker have the residual current detect function,you must
choice breaker the rating residual current more than 300mA.
notice
When using inverter with VDE-AR-N 4105, because the inverter's displacement
factor adjust function had to accorded to VDE-AR-N 4105,the PV-inverter
system total capacity cannot be over 13.8KVA. When using inverter with CEI 0-
21: if the inverter system total capacity more than 3KW and up to 11.08KW,the
displacement factor is adjustable between 0.95 leading to 0.95 lagging ,and
not need the external SPI.if the inverter system total capacity more than
11.08KW,,the displacement factor is adjustable between 0.9leading to 0.9
lagging ,and need the external SPI
.
You must install a separate single-phase circuit-breaker or other load disconnection unit for each
inverter in order to ensure that the inverter can be safely disconnected under load.
We suggest you choice the AC breaker rating current in this table:
SP6000
42A/230V
We recommend electrical connection as below
The AC wiring step
1.
The grid connection is contains using 3 conductors (L, N, and PE).
